Fuel from sunflower husks - new economical technologies for heating homes

Register Login

Publication date: January 16, 2019

A new product that came to us from Europe is fuel briquettes produced by hot pressing from biowaste - the husks of agricultural crops. This solution was created specifically for heating private households. Such briquettes arrived on the Russian market quite recently.

Fuel made from sunflower husks is always popular in Europe, as it produces the greatest amount of heat. It will also be useful in Russian conditions, especially since it is also produced on domestic lines - for example, in Altai. Those who want to try alternative eco-friendly fuels should start with this.

Main advantages

Fuel briquettes are a modern type of alternative fuel.
They can be used in any stoves, fireplaces, boilers, grills, barbecues. Eurobriquettes are cylindrical billets resembling firewood, or rectangular bricks. Small dimensions allow them to be placed in fireboxes of any size. What are briquettes made from? Most often, wood is used (sawdust, shavings, dust), but straw, paper, peat, coal, seed or nut husks, and even manure are also used. The composition of eurobriquettes can vary significantly, depending on what technology is used in production.

At the same time, all types of raw materials from which firewood can be produced are natural, absolutely natural. Making fuel briquettes at home will allow you to create an environmentally friendly product that will burn almost completely in the furnace firebox and at the same time emit a minimum of smoke.

A home-made eurobriquette can be used to light a sauna stove or heat a home. Since the raw material is compressed quite strongly and the amount of moisture is minimal, the fuel briquette burns for a long time, constantly releasing a large amount of heat. An interesting point was noticed by people who are already actively using such fuel: if you heat your barbecue with eco-wood and fry food on it, if fat gets on the briquettes, it will not ignite.

For stoves, boilers and fireplaces that burn solid fuel, sawdust briquettes are an excellent option. They flare up slowly, but then burn for a long time and emit a large amount of heat. This is explained by the high density of the pressed wood product. The heat transfer from briquettes significantly exceeds the level of heat obtained from the combustion of even the driest firewood, the storage and drying of which took at least a year.

The humidity of fuel briquettes is 8-9%, dry firewood, in turn, has an indicator of 20%. It turns out that a briquette made from the same wood burns better than the wood itself. This effect is formed due to the fact that when burning, fuel briquettes do not need to evaporate a large amount of moisture.

The briquette burns with a stable fire, without splashes, sparks, or crackles, and the amount of smoke released during combustion can be described as small. It is extremely convenient to put such fuel into the stove, since all products have the same correct shape.

A little trick: if you want to create an intense fire with high heat transfer, you should place fuel briquettes in the firebox at some distance from each other and, conversely, to maintain smoldering, you need to tightly connect all the eco-wood in the firebox.

Like any product, fuel briquettes are not without their disadvantages:

• First of all, it is worth noting that they are very vulnerable to moisture, so they are sold in cellophane packaging.
• Briquettes are not able to withstand mechanical stress, especially products made using RUF technology that are not fired on the outside.
• If you want to start making such things at home, it will cost you a pretty penny, although there will certainly be benefits in the long run. The fact is that you will have to purchase a grinding installation, a dryer and a pressing machine in order to carry out the entire cycle of work with raw materials. With suitable equipment, it will be possible to set up artisanal production of fuel briquettes even in your own garage.

Fuel briquettes - what are they?

Having a source of firewood at a bargain price is great. It's even better when you get them for free. In this case, you don’t even want to think about an alternative, since there is no practicality in it. It’s another matter when the choice is between traditional firewood and new types of solid fuel, which are approximately equal in price. In this case, you need to think about what is more profitable - to burn with briquetted fuel or with regular logs.

Fuel briquettes are a product of processing combustible waste, for example, ordinary wood chips. We cannot use wood chips to burn directly in a wood stove or boiler. There it will turn into a solid lump, which will give a minimum of heat. The resulting lump will have to be constantly stirred. Therefore, you can forget about such kindling.

How to get biogas at home

What raw materials are biogas made from?

• Shredded weeds (grass and leaves).
• Fruit and vegetable pulp.
• Grape pomace.
• Seaweed.
• Waste from fish and meat processing.
• Potato peelings and rotten potatoes.
• Brewery waste.

But most often, manure is used for these purposes as a raw material that is quickly decomposed by bacteria and is cheap.

To obtain fuel from manure or other raw materials, a biogas plant is built. It works on the same principle as septic tanks for autonomous sewerage. Organic matter is processed by anaerobic bacteria, and the biogas released is discharged through pipes and collected for subsequent use.

Making a biogas plant with your own hands helps save about 50% of the cost of a factory device. This speeds up the system's payback. In addition, the construction of the simplest type of installation to begin with allows you to assess how necessary such a device is in the household and invest gradually. This is much easier for the family budget than paying the entire amount at once.

Fuel briquettes from sunflower husks for heating. Advantages and disadvantages

You can heat stoves and solid fuel boilers not only with coal or wood. Fuel briquettes made from agricultural waste are becoming increasingly popular.

For their production, husks (husks) of sunflower, buckwheat, rice are used, straw, nut shells, etc. are processed.

The features of modern technology are such that most often the formation of a fuel briquette occurs only due to pressure without additional connecting elements.

When pressing, one of the components is released from the raw material - lignin, which provides the strength of the briquette.

Fuel briquettes made from husks. Burns for a long time and produces a lot of heat

With all the variety of raw materials, briquettes made from sunflower husks are more popular. This is due to the large amount of heat that such fuel releases during combustion.

Advantages and disadvantages of husk briquettes

In addition to the large amount of heat, what is attractive about briquettes is their density. Why is this so good? Firstly, you save on delivery (they usually charge per volume).

Secondly, the more compact the fuel, the easier it is to store.

Thirdly, if you compare it with firewood, then when you put the same amount of firewood and briquettes (it’s unlikely that you measure firewood in kilograms, because they lay the boiler by volume, and they sell firewood by the cubic meter), you get more heat from the briquettes than from even the best firewood. According to VNII TP, the heat from burning 1 kg of sunflower husk briquettes can heat an area of ​​50 m2 within 1 hour.

In the table below you will see how much heat the fuel produces. It must be said that fuel briquettes are far from in last place, but those made from husks are practically beyond competition.

It’s convenient to place briquettes in the firebox: their surface is smooth, you won’t get splinters, unlike firewood, and you won’t get your hands dirty, like when working with coal. There is another advantage: there is no need to improve or remodel the boiler. Did you burn with wood? Just buy briquettes and use them instead of firewood.

Another advantage of briquettes made from sunflower husks is the burning time: they burn for one hundred to one hundred and thirty minutes, and smolder for six or even eight hours.

A significant plus is the low ash content: after burning a kilogram of this briquette, only a matchbox of ash or a little more remains (depending on the quality, but for normal briquettes the ash content is in the range of 4-7%), hence the large amount of heat that a unit of fuel produces: it burns out it's complete. The ash formed after combustion is an excellent fertilizer and can be taken out to the beds.

Cylindrical briquettes from sunflower husks. They endure transportation worse, but burn well

Now about the disadvantages. There is essentially only one drawback: any briquettes (including those made from husks) are afraid of moisture and can crumble when wet. Therefore, they are demanding in terms of storage space: they must be hidden under a roof, in a dry room.

The high price is often cited as a disadvantage. If you look at the cost per kilogram, the price is really considerable. But if you calculate the cost of one kilowatt of energy, the picture turns out to be different.

Want to make sure? Find out the price of a kilogram of firewood, coal, briquettes, etc. Divide this value by the number of kilowatt/hours from the table. Get the cost per kilowatt of heat for each type of fuel.

You may come across the opinion that fuel briquettes of sunflower husks clog the chimney because they contain a lot of oils.

If it is not designed correctly or is faulty, it is possible.

If there is normal draft, the boiler works no worse than with wood and the chimney does not need to be cleaned more often.

Give GaZ

Fuel briquettes made from sunflower husks are not the best choice

Thanks to the government and everyone involved that this year many had to stop using gas for heating purposes. It has become a really expensive pleasure. If you wanted to go to Europe, get it and sign for it. Okay, I don’t like to make political fuss.

We live in a house, so we have a choice: heat with gas or-or. Now many people are thinking about how and with what to heat their home. There are various types of fuel briquettes on sale. In principle, taking into account various parameters, it’s for that price and it turns out as if you just buy firewood, but it must be dry, so now it’s not an option.

In search of the ideal fuel, we took pressed sunflower husks for testing. Why, because many people praise them and the price is one of the lowest on the market. In fact, wood burns longer and produces more heat. This is where the advantages end.

Now on to the cons. 1. Over a short period of use, these briquettes clogged the chimney due to which the draft deteriorated. 2. Due to poor draft, the smoke does not completely go into the chimney - it stinks of roasted seeds throughout the house. 3. They are afraid of moisture. The freshly opened bag is all intact and even. After a week, a third of the bag turns into dust - it cannot be stored outside or in the garage.

The man from whom they took the bag for testing says they need to be stored in a dry room. There are approximately 28 bags per ton, and why should you bring them all into the house so that they don’t get damp? To put it mildly, not seriously :) Afterwards, we took lignin briquettes, no problems have been observed so far, they are not afraid of dampness, they burn for a long time. The disadvantage is high ash content - but it is warm.

Here you will learn:

In this review, we reveal to our readers reviews of fuel briquettes. This type of solid fuel is becoming more and more popular; it has a whole army of admirers. And today it is actively used for heating houses and buildings for other purposes. Let's take a look at what fuel briquettes are and what consumers say about them.

Production

The production process, as we have already said, is quite simple, even though it takes place at home.

To make briquettes for heating stoves with your own hands you need:

• Prepare high-quality raw materials, grind them to the desired consistency, and dry them. In order to improve the quality of combustion, paper can be added to any raw material.
• If necessary, add a binding element (clay, lignin), add water, and load it into the press machine.
• Press the product into a suitable shape at high pressure and preferably high temperature.
• Dry the finished product and, if possible, package it to protect it from external factors. When drying, you can use rags and paper that can draw out any remaining moisture from the briquette.

Having carried out all this work, you will receive excellent fuel, which can be used to easily and quickly heat a bathhouse and heat a house. At the same time, over a long period of time, you will experience the benefits and cost savings from using such eco-drives.

Note that during operation you should try to achieve a briquette moisture content of no more than 10-12% so that they burn well. Industrially produced briquettes have a moisture content of less than 10%.

To make sure of the excellent characteristics of this type of fuel, you can buy yourself some Euro briquettes to try in any store. At the same time, to create a suitable atmosphere, you can sometimes light a fireplace or stove with ordinary wood, because the use of different types of fuel is not mutually exclusive.

Back in the middle of the last century, in many regions of our country, where there were problems with wood, but livestock farming was developed, dung was a popular type of fuel. Then they were supplanted by coal supplies and gasification, but the topic of producing fuel briquettes from manure is still interesting.

Nowadays, manure is most often used in organic farming, as a natural and useful fertilizer. But these are not all areas of use of this natural raw material. We talked about adobe houses, where manure can also be used as a filler for construction briquettes. In addition, organic material is used in the production of biogas, which is also an alternative fuel.

Preparation of dung. Tsimlyanskaya village, 1875–1876

But we will not talk about biogas, but specifically about fuel briquettes made from manure, dung, which were actively used by our ancestors to heat houses with stove heating.

Dung is not just manure, animal waste. This is manure mixed with straw, sawdust, hay, pressed into small briquettes, bricks or cakes, and dried. In this form, manure becomes a good fuel for heating, for example, a greenhouse, a bathhouse or a country house, completely replacing firewood and even coal.

For comparison, here are the approximate energy content of various types of biological fuel:

As you can see, the specific calorific value of dry manure is even slightly higher than that of firewood that was dried outside. In addition, dung burns with a smoldering flame; users note that their combustion properties are similar to brown coal.

The main advantage of manure as an alternative fuel is its efficiency. If you have your own farm - cows, goats, sheep, rabbits, other animals - then the fuel is absolutely free. You can ask your neighbors who farm and do not actively use manure themselves. A whole truck of manure can be ordered and purchased; it will cost about 11 thousand rubles.

Another plus is that ash from dung will be an excellent fertilizer; it is an environmentally friendly and waste-free fuel.

The main disadvantage of dung is that it takes a long time to make such fuel with your own hands; you have to put in a lot of effort. In addition, the very thought of having to tinker with such organic raw materials, animal feces, scares many people away. Note that, according to numerous reviews, there are no unpleasant odors during the burning of dung. Bread was previously baked in Russian ovens using this fuel.

In the process of producing briquettes from manure, of course, there is little pleasant, we agree. But in general, everyone involved in livestock farming is faced with the disposal of organic waste, so why not do it for the benefit of the farm.

What are pellets?

These are granules obtained from crushed raw materials by pressing. They have a cylindrical shape and a hard consistency. For their production, various natural materials are used: wood, straw, peat, cereal husks, and sunflower husks. Pellets from it are a by-product of sunflower oil production. The density of the granules is slightly more than one thousand kilograms per cubic meter of volume.

Typically, granules are 50 mm long and their diameter reaches 4-10 cm. The color of a high-quality granule is gray, and the surface is glossy, which should be free of defects in the form of cracks. If they are found during inspection, it is a defective product. Consumers facing such problems believe that the technology was violated during the production process or the air in the room was too humid, above the permissible norm. The granules must be dry. This is determined by their weight.

Equipment used

In order to make a fuel briquette with your own hands, you need to choose the right press or chipper. When choosing a press, you need to decide what shape and area the elements will have. The most commonly produced are round and rectangular briquettes.

Professional equipment includes auger, mechanical impact and hydraulic presses. The first device is capable of producing octagonal elements with a small hole in the center. They are distinguished by maximum density, therefore they provide the longest burning time. The hydraulic press produces rectangular elements with the lowest density, which ensures high material consumption. Making fuel briquettes at home using a mechanical impact device gives you the opportunity to make material of any shape. In this case, the elements have an average density.

You can make a machine for making briquettes at home. To do this, you will need a simple press and a mold (a sewer pipe with drilled holes). Please note that during the manufacture of the presented product you will need to take into account the length of the firebox.

Pricing and determination of retail or wholesale prices for briquettes

Different businesses use different pricing methods. However, regardless of the method chosen, you must first have certain information that will allow you to make the right decision. The most important information for pricing is:

• acceptable price level for buyers;
• competitors' prices;
• expenses for the cost of finished products;
• other expenses: advertising, delivery, company management.

Much of this information for determining sales prices comes from market analysis. First you need to answer the question: “What price is the buyer willing to pay for the product?” Next, we determine at what prices competitors sell. And then we analyze the costs of producing and selling briquettes, which should be covered by the selling price:

1. Direct purchasing costs are those costs that can be directly associated with each batch of purchased materials and raw materials for production. They can be attributed to a person without any additional calculations for products including them: purchase of raw materials, fuel, transportation, packaging.
2. Fixed costs – carrying out operations is also a fixed cost that does not depend on the number of goods sold. This includes wages (if you hire workers), overhead, electricity, waste removal, financial and accounting services, insurance, security and controls, telephone and internet, office supplies, promotions and advertising, and office rent.

For one ton of straw briquettes, individual clients are willing to pay up to $120. Enterprises and large boiler houses count on wholesale discounts of up to $80 per 1t.

Despite the relatively new type of solid fuel, there are already many competitors on the market today. Some of them produce briquettes from sawdust or willow branches

Therefore, it is important to stand out among competitors with a high-quality product with good combustion and heat transfer performance. It is equally important to regularly analyze the degree of customer satisfaction in different market segments, which are constantly changing

To solve these problems, you should know how to conduct marketing analysis for small businesses. Market analysis will not only allow you to track undervalued segments, but also create a strategy for business development in accordance with the growth rate of its potential. And also to identify the most favorable entry point into the market.

Customers' opinions

How objective can reviews of peat heating briquettes be? The catch lies in the many external factors that affect the effectiveness of their use. First of all, this concerns the boiler, since the efficiency of heating with briquettes made from sawdust or other source material depends on its parameters:

• We decided to heat the boiler with sawdust briquettes as an experiment. The heat transfer turned out to be extremely high. However, fuel consumption has also increased. Alas, our old boiler had too much draft. Now we use them if we need to quickly heat the house;
• First, we ordered the cheapest fuel briquettes in the form of tablets. They burned out quickly and produced a relatively large amount of ash. Then we decided not to save money and bought a batch of RUF Euro firewood. The differences turned out to be significant - the complete combustion time increased, heat transfer increased;
• We approached the issue of heating the house thoroughly - we purchased a long-burning boiler. They took peat fuel briquettes for testing. After much testing and experimentation, we found out that it is best to use them together with firewood in a 1/3 combination (briquettes, firewood).

DIY heating briquettes

Is it difficult to make wood heating briquettes at home without special equipment? To do this, you will need the simplest lever press and a mold for Euro firewood.

Sawdust or waste paper can be used as feedstock. Often these components are combined with each other to improve quality. To obtain a homogeneous mass in a peat heating briquette, a binder component is required. It could be water or clay. Then you will need to complete the following manufacturing steps:

1. Crushing the feedstock and adding a binder component.
2. Filling the form, pressing.
3. Drying the workpiece.

Factory heating briquettes RUF are produced using the same technology. The difference lies in pressure and production volumes. At home, to provide fuel for the entire heating period, production time can take from 7 to 20 days.

Market situation

It is for heating houses that fuel briquettes have become especially popular, since the heat from their use will be much more pleasant than the heat coming from coal or natural gas. The great demand for European firewood is growing strongly, but there are no prerequisites for the modern market to become oversaturated with such products. In the Russian Federation, the market for such material is already actively gaining momentum. Many people who buy country property are well aware that it is possible to heat their purchased homes using wood waste boilers and fireplaces. So the equipment is purchased with great joy. And in Europe, heating homes using fuel briquettes is already commonplace. Many supermarkets may sell different packages of granules of varying sizes.

Sales market for fuel briquettes

And yet, fuel briquettes are perfect for use in production facilities. Every factory that uses solid fuel for heating may well end up switching to fuel briquettes. Thus, the business plan for the production of fuel wood briquettes will be more profitable.

Market analysis

The rapid development of the biofuel market is associated, first of all, with the energy challenges that exist in European countries and the significant rise in cost of traditional fuels. In Russia, interest in the production of fuel briquettes began to appear at the turn of the 21st century, when the country's first pallet manufacturing enterprises were organized. In 2004, the biofuel industry formed into an independent business line, which in recent years has undergone a number of significant structural and qualitative changes.

If at the initial stage of the development of the industry in the country there were only about 30 active manufacturers, and of these only 3-4 trading companies were able to enter the international market, now their number has not only increased significantly. Industry magazines and reference books appeared in Russia, and conferences and seminars began to be held on topical issues in the development of the alternative fuel market.

These efforts have led to the fact that since 2002, the number of European firewood producers has doubled every year. According to experts, this trend will continue in the future. This happens even under such conditions that domestic enterprises for the production of briquettes constantly experience a shortage of raw materials. If this fact in itself is paradoxical for Russia, then other restraining barriers are quite natural: the country does not yet have an established production of special equipment, there are no qualified specialists, and the entrepreneurs themselves have a lack of experience in operating in this product market.

The consequence of all these circumstances is a constant rise in price (by 5-80%, depending on the region) of purchase prices for fuel briquettes.

Abroad, Russian products from this industry cost 80-230 euros per ton. This is facilitated by the gradual accumulation of experience in the industry market by domestic entrepreneurs, the widespread popularization of this type of fuel among the population, the high profitability of the production itself (at least 15%), and the active investment of funds from foreign companies in the domestic industry.

At the moment, the colossal potential of domestic bioenergy is undeniable. But, according to experts, for continued market growth, two basic conditions must be met:

• It requires a transition from competition between domestic producers to cooperation, which will lead to the exchange of experience and knowledge.
• Government support for the industry is needed.

To date, certain steps have already been taken in this direction. Thus, the Federal Energy Strategy for the period until 2021 was adopted, which provides for the creation of a more favorable investment climate for producers of renewable energy sources, the widespread introduction of modern technologies for the production of biofuels, and the organization of production of domestic equipment for this industry.

It is expected that as a result of the implementation of this strategy, the share of renewable energy sources in the country’s fuel and energy complex will reach 0.6% in 2021 (in European countries this figure is going to be increased to 15%). There is a special commission in the State Duma of the Russian Federation that is developing draft laws in the field of alternative energy.

In a word, bioenergy in Russia has the necessary prospects to soon become a developed, environmentally friendly, competitive and profitable sector of the national economy. In the foreseeable future, the demand for fuel briquettes will only increase, which will lead to increased competition and the survival of only efficient manufacturers in the market, the number of which will also grow.

Benefits of granules

Sunflower husk pellets have a number of advantages:

• Environmentally friendly - they do not contain chemicals, plant spores, or seeds that cause allergic reactions.
• Economical - the cost of granules is low, especially in sunflower growing regions.
• Functionality - granules can be stored for a long time, since their biochemical activity is low.
• Relatively low price, without seasonal increases. According to consumer reviews, this is a valuable advantage of this type of fuel.
• The absence of special storage conditions that do not require additional space. This is due to the fact that the granules have a high bulk density.

• There are no difficulties during transportation, since the granules have standard sizes and are free-flowing. This is especially true for hard-to-reach areas of our country, where it is not possible to use traditional types of fuel. Sunflower husk pellets come to the rescue, as they can be transported over any distance.
• The possibility of using an automated combustion process without time-consuming intervention for maintenance, which is associated with low zonality.

How briquettes are made in large companies

As already mentioned, briquettes are made from waste from production processes. The first most popular use is wood (and/or sawdust); The hottest material is oily cereal crops. Large-scale production lines (conveyor lines) require several processing steps. And each stage, in turn, requires certain equipment, namely:

• Grinders – crumble raw materials to the required size. The smaller the individual piece, the denser the briquette will be made, therefore, the more heat it will produce.
• Calibrators “select” from a huge variety of crushed parts those that should go through the first stage additionally.
• Drying chambers - the raw materials obtained at this stage have high humidity, which, of course, is in no way suitable for ignition. The purpose of the chambers is to reduce the moisture level to the required level.
• Press – compresses crushed and dried raw materials.
• Packaging machine – completes production by wrapping the briquettes in cellophane, thereby providing protection from outside moisture.

How to make a press for making briquettes yourself

It is hardly possible to make equipment for the production of fuel briquettes using extrusion (pressing at high temperatures) with your own hands, but an ordinary press can be built even from improvised means.

This video demonstrates an original approach. Making such a press is not the most difficult task, and the yield of product from one press is decent. It can easily be adapted for pressing sunflower husks, only it will need to be crushed first.

In general, our people are generous with all sorts of inventions. Everyone’s culture of implementation is different, but those who can do it do what they can. Here is a selection of photos that also show homemade presses for making fuel briquettes, including those made from sunflower husks.

The simplest version of a homemade press for briquettes made from husks, straw, rice husks, buckwheat, sawdust

You can also make such a press for briquettes from husks, straw, sawdust yourself.

Preventing problems

If the briquettes were made in accordance with the technology, they only need paper and a few twigs to ignite. They burn evenly, with equal intensity, producing large volumes of thermal energy when air is supplied. For the same reason, lovers of bathing procedures, who are accustomed to heating stoves with logs, quickly render them unusable by burning briquettes.

Compared to sawdust bricks, charcoal briquettes burn even hotter. They provide a temperature of 900°C versus the 700°C produced by sawdust. This is why they are not suitable for steel ovens. The latter are intended only for wood.

Recently, briquettes have begun to be produced everywhere. There are many unscrupulous manufacturers. They use almost any material they can get their hands on to make cheap fuel. It is not surprising that already at the transportation stage these materials crumble into dust. Homeowners can only wonder why low-quality fuel produces so little heat and leaves impressive amounts of ash. It turns out that when purchasing, you should never look for the cheapest options, as there is a risk of stumbling upon low-quality raw materials.

Organization of the straw preparation process

Now we will give some considerations on organizing the straw preparation process. Unlike sawdust, at the initial stage of processing we have straw in bales or rolls. At the same time, the density of the baled material is significantly lower than the density of sawdust. This allows you to use a different method of drying raw materials in contrast to drying sawdust. The most efficient way is to dry the straw directly in the bales. In this case, you can use simple chamber dryers similar to wood dryers. Considering the possibility of using a hard drying mode, it is possible to use a dryer of the simplest design without special equipment and automation. According to our estimates, the productivity of such a dryer will be very high, and the costs of its creation are not comparable with the costs of purchasing a good drying unit for sawdust. After drying, the straw must go through the stages of cutting and crushing

There is one more circumstance that should be noted. Considering that straw is harvested mechanically, soil particles are present in the baled straw. During processing, this abrasive will have a negative impact on the working tool of the press. To eliminate this drawback, there are two solutions: - radical - using a centrifuge to separate the abrasive from the crushed raw materials; - use of a special tool. Considering the productivity of the press, you need to prepare up to 9 tons of raw materials prepared for pressing per day

Hence the required volume of the drying chamber. Of course, dryers used for sawdust can also be used to dry chopped straw. Otherwise, the process is similar to the production of briquettes from sawdust. Equipping the process with mechanization means, organizational decisions and layouts depend on the specific conditions and capabilities of the manufacturer

We declare with full responsibility the possibility and necessity of widespread implementation of the technology for the production of fuel briquettes from crop waste. This technology allows us to solve the problems of recycling unclaimed waste and produce highly efficient environmentally friendly fuel from renewable sources of raw materials.

Turnkey construction of a husk boiler house

When creating a “correct”, that is, an effective boiler house using husks, highly specialized experience is required among the employees who are involved in this. At its core, this experience is nothing more than “know-how”, without which it is impossible to achieve complete combustion of husks, high efficiency of boilers (boiler room), low emissions of air pollutants, etc. and so on.

The specialists of Sibpromenergo Holding Company have this experience. At one time, Biysk Boiler Plant OJSC spent many years to develop optimal combustion of agricultural waste. The main ways to solve this problem were chosen by the specialists of this particular enterprise. Now combustion methods continue to improve.

The vortex combustion technology has been successfully implemented by Sibpromenergo Holding Company at several facilities and is patented by our developers. The company’s specialists have been in constant, long-term contact with many owners and managers of enterprises where husk boiler houses have been built according to our designs. This allows us to receive feedback from facilities and accumulate invaluable experience in the design, construction, reconstruction and operation of such installations.

Moreover, many of our clients eventually become our partners. We see and understand their needs, they are our capabilities, and joint work is built on this basis of trust. Here is how one of our long-time partners responded to such cooperation:

You can get acquainted with the Review of Quantserver in more detail on the Reviews page.

For many enterprises located in agricultural regions, a husk boiler house is a good strategic opportunity for their development. Unfortunately, it is not often possible to see how waste is turned into income. But this approach is the future!
