Woody fuel briquettes(eurowood) have a wide range of applications and can be used for all types of solid fuel stoves and central heating boilers, etc. They burn well in sauna stoves, fireplaces, grills, barbecues, etc. Also used in industrial heating, on railway transport etc.

CHARACTERISTICS OF BRIQUETTES, PELLETS AND COAL*

Pini&Kay/Pini Kay

(octagonal bars with a longitudinal hole)

9800 rub/ton (mix)

10500 rub/ton (birch)

Length - 250 mm
Section - 65x65 mm (from edge to edge)

Diameter of circumscribed circle - 70 mm
Hole diameter - 20 mm
Humidity - 7-9%

Ash content - 0.5-1.0%

1 packaging (250x360x130 mm) = 10 kg (+/- 5%) = 12 briquettes tied with plastic strap tape in transparent shrink film.

Pini&Kay, compared to other wood briquettes, has the highest heat transfer, mechanical strength and the lowest hygroscopicity (due to heat treatment surface). The hole allows you to create draft inside the briquette, promoting combustion without forced ventilation, which makes it possible to use Pini&Kay in fireboxes with low draft. Due to the hole, which increases the combustion area, Pini&Kay flares up faster and heats the room faster than other briquettes. Pini&Kay briquette is number 1 among wood briquettes.

Nielsen/Nielsen

(cylinders)

9800 rub/ton

Length - 270 mm
Diameter - 90 mm
Humidity - 7-9%
Heat of combustion - 4850-4950 kcal/kg
Ash content - 0.5-1.0%
1 packaging (270x360x90 mm) = 10 kg (+/- 5%) = 6 briquettes in transparent shrink film.

Nielsen briquettes, due to their high density, are not inferior in heat transfer to Pini&Kay briquettes, and even slightly exceed them in burning time. Just like Pini&Kay, Nielsen briquettes belong to the class of premium briquettes.

RUF/RUF

(bricks)

from sawdust (mix) - 6800 rub/ton,

from sawdust (birch) - 7500 rubles/ton,

from wood dust (birch)- 7800 rub/ton

Length - 155 mm
Width - 95 mm
Height - 65 mm
Humidity 8-10%
Heat of combustion - 4400-4500 kcal/kg
Ash content - 0.9-1.0%

1 packaging (380x195x155 mm) = 10 kg (+/- 5%) = 12 briquettes in a transparent bag polyethylene film or in shrink film.

RUF briquettes are the golden mean, the most widespread and popular briquettes on the market. They have an optimal combination of price/quality balance. RUF from wood dust a little (~ on 5% ) is superior to its sawdust counterpart in terms of heat transfer and combustion time, but these advantages are felt only in long-burning boilers with automatic control. In simple boilers and furnaces, the difference between them is not so obvious.

Peat briquettes "Standard"

n not in stock

Characteristics:

Dimensions 170x70x30-100 mm
Humidity<16%
Ash content<14-16%
Heat transfer - 3600-3800 kcal/kg
Sulfur content<0,35%

25 kg (+/- 5%).

Peat briquettes boast the longest burning time compared to wood briquettes. But peat briquettes also have a number of disadvantages: heat transfer is less, they take longer to ignite (wood briquettes or firewood are needed for ignition), and they leave an order of magnitude more ash after burning. Many consumers use the main advantage of peat briquettes - a long burning time, to maintain a comfortable temperature in the room at night, so as not to wake up to refill the stove or boiler, and in the daytime they switch to wood briquettes.

Peat briquettes "EURO"

9500 rub/ton

Characteristics:

Dimensions 180x80x30-50 mm
Humidity<10%
Ash content<13%
Heat transfer - 4500-4600 kcal/kg
Sulfur content<0,2%

1 packaging (400x200x160 mm) = 10 kg (+/- 5%) = 16-20 briquettes in transparent shrink film.

Peat briquettes "EURO" or peat briquettes of the "new generation" are made from purified (separated) peat and have a higher density, so their heat transfer is at the level of wood briquettes. Having inherited the best properties from peat briquettes of the “old generation”, EURO briquettes minimized their disadvantages. Another obvious advantage of EURO briquettes is their packaging in 10 kg plastic bags, which makes them easier to carry. The optimal solution, proven over the years by our numerous clients, is the use of peat briquettes at night (the burning time of one bookmark allows you to maintain heat in the house all night), and during the day (and for igniting peat briquettes) - the use of wood briquettes.

Peat briquettes "Cylinder"

8800 rub/ton

Characteristics:

Dimensions 78x30-90 mm
Humidity<15%
Ash content<5%
Sulfur content<0,25%

Packaged in polypropylene bags 25 kg (+/- 5%).

Peat briquettes "Cylinder" are practically not inferior in their characteristics to briquettes "EURO". Thanks to cheaper packaging - packaging in plastic bags, they are a more affordable alternative. Based on the price-quality ratio of consumer properties, they are considered the optimal choice among peat briquettes.

Sulfur content<0,2%

Packaged in paper bags (kraft bags) 15 kg (+/- 5%).

Coal briquettes is a modern type of solid fuel for stoves and boilers running on coal. They are produced by pressing coal chips. Combining the advantages of coal, such as high calorie content and burning time, coal briquettes have a number of advantages compared to conventional coal:

• They do not sinter, do not form slag deposits, only ordinary ash - it is easier to remove waste and control the combustion process.
• Coal has a lower density compared to briquettes. Conventionally: bucket of coal = 5kg, bucket of briquettes = 10kg. Accordingly, with the same volume of fuel added, the burning time of one fill increases, so less fuel is required for a full-fledged firebox.
• Briquettes are more permeable when burning than lump coal. The briquette burns completely, and you receive all the thermal energy contained in it. The result is an increase in the efficiency of heating devices up to 30% .

*Parameters may vary slightly based on the manufacturing process.

Fuel briquettes and pellets are not subject to mandatory certification in the Russian Federation, however, we have passed voluntary certification. All products are manufactured using European-made equipment and comply with German DIN standards, Russian GOST R 55115-2012, GOST 55523-2013 and TU 5322-001-00257466-2016 (confirmed by laboratory test results).

COMPARISON OF WOOD BRIQUETTES WITH OTHER TYPES OF FUELS

Calorific value:

firewood with natural humidity (50-55%) ~ 1500 kcal/kg.
Those. when buying 1 ton of wood, you actually buy 500-550 kg water, the evaporation of which will take about 25% of the remaining real fuel.

naturally dried firewood (humidity 40-45%): pine ~ 1800 kcal/kg, birch ~ 1900-2100 kcal/kg

Boiler efficiency when using eurowood increases by 30-50% compared to conventional firewood.

Sulfur release when burning Eurowood<0,2%, что позволяет Clean the chimney 3-4 times less often than when using wood or coal.

Time burning and smoldering of briquettes on average 2.5 times higher than conventional firewood, they also ensure constant combustion temperature. This means that compared to conventional firewood, firebox stash can be produced 2-3 times less often.

Fuel briquettes are becoming more and more popular today.

They replace conventional firewood and other types of solid fuel. What types of briquettes are there for heating stoves, and in what cases is it better to give them preference?

Briquettes for heating stoves are a type of solid fuel, which is characterized by an equal shape and the same size. Fuel briquettes tossed
They are used in fireplaces, solid fuel boilers and other heating devices in private homes. Numerous reviews suggest that fuel briquettes are an excellent alternative to the usual firewood or coal.

Basically, briquettes are the result of appropriate processing of products from the woodworking and food industries. They can be made from sawdust, rice or buckwheat husks, and even from seeds, as well as from straw, peat or tyrsa. Binders and sometimes glue are added to the main component. The composition of the briquettes is indicated on the packaging or in the relevant documentation. The composition affects the strength and shape of the briquettes and, of course, heat transfer, combustion rate, the amount of soot produced and other indicators that are significant to the user.

Special briquette production technologies involve ultra-strong pressing and maximum drying. Fuel briquettes are often called Euro firewood. This is deserved, since it is an excellent alternative to conventional firewood, and compliance with high quality standards allows this fuel to burn without the slightest harm to the atmosphere or human health.

1. Fuel briquettes from sunflower seeds produce the most heat (5151 kcal/kg), are characterized by the lowest ash content (2.9-3.6%), and also contain a high concentration of oils. Due to the oil, their energy value increases, but the clogging of the chimney with soot is also high.
2. Fuel briquettes made from wood are second only to seed briquettes in terms of heat transfer (5043 kcal/kg). The ash content is the same as that of conventional firewood (0.5-2.5%).
3. Straw briquettes are slightly inferior to seed and wood briquettes in terms of heat transfer, but their indicator is still decent (4740 kcal/kg), but the ash content is let down - also rather large (4.8-7.3%).
4. The fuel in tyrsa briquettes is characterized by very low ash content (0.7%) and very decent heat transfer (4400 kcal/kg).
5. Rice husk briquettes are not very profitable - as much as 20% ash content and heat transfer of only 3458 kcal/kg.
6. Peat briquettes deserve special attention. The specificity of the material determines their high ash content and the presence of harmful impurities in the composition. Therefore, they are not recommended for home use, but are more often used in industrial boilers and furnaces, where the main need is for low-quality and inexpensive fuel.

What shape of fuel briquettes is best for you? take

Fuel briquettes are given a variety of shapes, but for a reason. The shape determines the density of the briquette, and this affects the air circulation in it and determines the combustion process.

Fuel briquettes are given the following three forms:

• Pini-Kay - briquettes of the highest density (1.08-1.4 g/cm3), in the shape of a square or hexagon with a through hole in the center for the best air circulation;
• Roof – sawdust briquettes, which are pressed into bricks of small size but low density (0.75-0.8 g/cm3);
• Nestro are cylindrical briquettes with an average density compared to Pini-Kay and Ruf (1-1.15 g/cm3).

Advantages of briquettes compared to firewood

Numerous experience in using fuel briquettes shows that they have a number of advantages over conventional firewood:

• high combustion temperature - on average twice as high as that of firewood; for example, the calorific value of wood is about 2500 kcal/kg, and briquettes – more than 4500 kcal/kg;
• low humidity - drier firewood gives off more heat, but even the best, properly stored firewood has a humidity of 15-20%; The moisture content of briquettes is estimated at 4-8%;
• high density - denser firewood, oak for example, burns better, but the density of oak is 0.8 g/cm3, and poplar 0.4 g/cm3; briquette density 0.95-1 g/cm3;
• briquettes are much more compact, burn evenly and last for a long time, are made from waste, which means no harm is caused to the environment during their production;
• Even the most sooty varieties of briquettes pollute the chimney less than burning wood.

All these advantages of fuel briquettes are due to their production technology. The use of special techniques is aimed at ensuring that the product is superior to ordinary firewood in terms of heat transfer, density, humidity, size, and other characteristics.

It would not be fair to say that fuel briquettes are completely devoid of any disadvantages. Among the things that stop you from regularly using briquettes are:

• high cost compared to firewood - however, if you evaluate the performance, then in fact briquettes will be more profitable;
• strict adherence to storage conditions - in particular, briquettes need to maintain low humidity; when damp, they crumble. A closed and well-ventilated room is required;
• the likelihood of fakes and low-quality briquettes - when purchasing, it is important to pay attention to the composition of the briquettes, because wood briquettes, for example, may contain soft wood, rotten or old raw materials, or chemically treated wood. This adds volume but reduces quality.

Fuel briquettes are an alternative material that allows you to quickly and efficiently light a stove or fireplace and warm up the room. At the same time, it has many other advantages. Today this type of fuel is becoming very popular. Let's look at why.

Advantages of the presented material

So, the main advantages of these elements are the following.

1. Making a fuel briquette with your own hands is quite simple, so you can do it yourself, using simple devices - presses. Plus, you can even start your own business.

2. Long burning time. The briquette can burn from 1 to 4 hours. At the same time, it constantly generates heat.

3. Minimum amount of smoke and sparks.

4. Environmentally friendly, as they are made with their own hands from plant and other natural materials.

5. Cost-effective. The cost of one ton of such fuel is significantly less than the same amount of coal or firewood. At the same time, energy efficiency is much better.

6. Practicality. The ash that is formed after the combustion of briquettes can be used as fertilizer.

7. Easy to store. The presented material does not take up much space and can be stored in plastic bags. At the same time, it can be stored for a long time in conditions of high humidity.

8. Application in all types of fuel equipment: fireplaces, boilers, stoves.

9. Easy to store.

Areas of application of the material

Before you make a fuel briquette with your own hands, you need to figure out where it can be used. Most often, the material is used for heating residential buildings, educational institutions, and catering establishments.

In addition, fuel briquettes can be used in warehouses where wood materials are dried and stored. Industrial enterprises also often use this type of fuel in combination with other materials. In any case, the presented material is as efficient and economical as possible, especially in comparison with other types of fuel.

What raw materials are used in production?

Before you make a fuel briquette with your own hands, you need to select the necessary starting material and equipment. First, let's figure out what the product can be made from. So, most often wood and plant waste are used in production.

For example, you can make a briquette at home from vegetable husks, sawdust, and straw. In addition, it is also allowed to use materials such as fallen leaves, shavings, dry plant stems, wood chips, and seed husks for production.

Naturally, for production you will also need water, clay and other substances that can glue the raw materials together. In some cases, starch can be added. In general, you can use any flammable waste that is lying around on your property to make briquettes.

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. 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.

Material manufacturing technology

The production of fuel briquettes consists of several stages:

1. First you need to grind the waste that will be used for the production of elements.

2. Dry clay should be added to the same container, which will serve as a binding link.

3. Now you need to add water to this mixture. Moreover, the gruel should not be too liquid or thick. In any case, the mass should mold well. In addition, the density of the briquette depends on the amount of water.

4. The resulting mixture must be poured into the mold and flattened with a press. Make sure that as much water as possible comes out of the slurry. After this, the resulting products must be thoroughly dried in the sun. In order for them to be durable, each element should be covered with paper or rags. After complete drying, all briquettes can be stacked together.

When you press the raw material with a press, you will have to exert quite a lot of force to squeeze out as much water as possible from the mixture.

Making fuel briquettes with your own hands is a fairly simple matter, although labor-intensive. Please note that the humidity of each product should not exceed 13%. In order for the element to burn better, during manufacturing you can add paper, which needs to be torn into small pieces. And so that all the components stick together better, you can add a little starch to the mixture.

Please note that you will need different briquettes for different types of heating devices. For example, peat and birch elements are well suited for fireplaces. For barbecues, it is better to use European firewood or wood briquettes. They can either burn or slowly smolder. In addition, they practically do not emit any carcinogenic or other harmful substances.

Now you know how to make a fuel briquette with your own hands. Good luck!

Anti-advertising of firewood on the packaging of fuel briquettes - is it true?
We select equal weight portions of fuel briquettes and birch firewood.
We light both firewood and briquettes using newspapers and birch bark.

Wood briquettes are a modern fuel option. It is produced from wood processing waste - compressed wood shavings and sawdust. Wood briquettes are an environmentally friendly type of fuel that does not contain any “chemical” additives. Bonding of particles occurs under high pressure due to lignin, a polymer contained in the wood itself. Fuel briquettes are conveniently packaged in plastic or cardboard boxes and take up little space during transportation and storage. The humidity of fuel briquettes when properly stored is no more than 8-9%.

When burning briquettes, little ash is formed, they burn longer than wood, and produce more heat. That's what the advertisement says, anyway. Are there any disadvantages to fuel briquettes? Like everything good and convenient, there is only one drawback - the high price.

Let's compare prices for firewood and fuel briquettes

In retail, Ruf type fuel briquettes (in the form of bricks) cost approximately 70-75 rubles. for 10 kg, and they are sold wholesale for 6,000 rubles. per ton. Since the density of fuel briquettes is approximately 950 kg/m 3, we can assume that a cubic meter of fuel briquettes costs about 6,000 rubles. (we do not consider briquettes of other types, since their cost is significantly higher).

How to compare the cost of fuel briquettes with the cost of firewood?

As you know, firewood is most often sold in bulk or stacked. If you received stacked firewood on pallets, then a cubic meter of such firewood is equivalent to 0.7 cubic meters in terms of dense wood. If you were brought firewood in bulk in the back of a truck, then with a firewood length of 30-35 cm, the cubic meter will contain only 52% dense wood.

In other words, to compare the cost of bulk firewood for dense wood with the cost of fuel briquettes, the cost of firewood should be doubled.

So, let's compare prices. Bulk firewood in the Leningrad region costs 1,500-1,600 rubles. per cubic meter. In terms of dense wood, a cubic meter of firewood will cost 3,000-3,200 rubles. In neighboring areas, firewood can cost about one and a half times less. Thus, a cubic meter of Ruf type fuel briquettes costs the buyer, depending on the area, 2-3 times more expensive than firewood.

We decided to find out whether such a difference in price is worth the stated advertising advantages of fuel briquettes in the form of convenience, increased heat transfer and increased burning time of fuel briquettes. We conducted an amateur experiment, which, although it does not claim to be scientifically reliable, can clarify some aspects of the use of fuel briquettes instead of firewood.

How briquettes and firewood burn

We compared fuel briquettes made from hardwood sawdust with birch firewood, which was stored under a canopy in the open air for more than a year.

Equalizing the chances of firewood and fuel briquettes in our competition, we selected the amount of firewood equivalent to the mass of two fuel briquettes (approximately 2.2 g). Although this comparison is not entirely adequate: stale firewood can contain from 12% to 25% and even up to % moisture, while in fuel briquettes the moisture content rarely exceeds 8-9%.

For kindling, place fuel briquettes on paper and birch bark in the fireplace. We place firewood in exactly the same conditions: we melt it using paper and birch bark. Both firewood and fuel briquettes ignite and burn equally well.

Fuel briquettes burn slowly, the flame is small and ugly. Fuel briquettes burn much more vigorously if they are placed vertically. But if you need a beautiful flame in the fireplace, and you are not ready to burn the entire package at once, then fuel briquettes are still not for you.

With a small flame, little heat is generated - you can safely sit at a distance of 1 m from the fireplace.

But when wood burns, so much heat is released that I was forced to move away from the fireplace - it is simply impossible to sit closer than 2 m because of the heat.

The first hour has passed. The briquettes have not decreased much in volume and burn slowly. And the firewood had already been broken into coals, but small tongues of flame were still dancing on them. The time for complete (until the flames disappear) combustion of three birch logs weighing 2.2 kg is 1 hour (anti-advertising of firewood on the packaging of fuel briquettes stated that firewood burns out in 30 minutes, which is not true).

I had to break the briquettes into coals around the 90th minute of burning. The total combustion time of fuel briquettes is 2 hours exactly, which corresponds to the stated time on the packaging of the briquettes.

Both firewood and fuel briquettes ignite and burn equally well.

Birch firewood, as expected, burns with a large, beautiful flame. Fuel briquettes burn more slowly and give off heat less intensely.

The result of comparing the firebox with briquettes and firewood

Fuel briquettes actually burn longer than birch firewood, but the difference is not as great as stated in the description of the briquettes. But at the same time, the intensity of heat release when burning wood is incomparably greater. The amount of ash after briquettes actually remained less than after birch firewood, but not by several times, as stated, but by only 25-33%.

Thus, in my subjective opinion, a 2-3-fold increase in the price of fuel briquettes over birch firewood in the current price conditions with constant operation does not justify itself economically. Since inexpensive fuel briquettes do not produce a large flame, using them in fireplaces and fireplace stoves, which are installed, among other things, to obtain aesthetic pleasure from contemplating fire, does not make much sense.

At the same time, fuel briquettes have a number of undeniable advantages: they are compactly packaged, leave little debris and less ash. A long burning time allows you to add fuel to the stove or fireplace less often. Although regular firewood is better suited for quickly warming up a cold house, fuel briquettes can be successfully used to maintain the required temperature in the house.

Since I come to the dacha intermittently during the heating season, it’s easier for me to buy several packages of fuel briquettes at the supermarket than to buy a carload of firewood for the season. In the cold season, in my house with an area of ​​120 m2, which is well insulated, it takes two packages of fuel briquettes (20 kg) to warm up on the first day, and to maintain the temperature in the following days - 1 package per day in light frosts and 1.5 -2 packs per day in severe frosts (subject to additional heating with several electric convectors).

Thus, each type of fuel has its own advantages and disadvantages. Knowing about them, everyone can choose the optimal type of fuel depending on the mode of operation of the house and personal preferences.

A fuel briquette is one of the varieties of solid fuel, and is a modern substitute for “classic” firewood. The use of briquettes allows you to increase the efficiency of stoves and fireplaces, as well as reduce waste output.

What it is?

Today, fuel briquettes are made from a variety of materials. In general terms, they are a compacted (compressed) “brick” consisting of wood waste or analogues.

Briquettes can have different shapes, which is determined solely by the pressing technique and equipment. The briquettes do not have any serious differences due to their shape. The only exception is specialized ovens that are adapted to a specific shape of briquettes.

Briquettes are made from the following materials:

• Wood (including in the form of dust, sawdust, etc.). This option is the most common due to its ease of production, low price and good heat capacity. Typically, briquettes are made from coniferous wood, birch or oak. The specific type of wood has virtually no effect on the cost of briquettes, since it is, in any case, a production waste.
• Sunflower and cereal seed husks. Briquettes of this type are distinguished by a darker color and a specific smell. In addition, they are the leaders in the amount of heat generated. On the one hand, this increases their energy efficiency. On the other hand, husk-based fuel briquettes produce more soot, which leads to the need for more frequent and more thorough chimney maintenance.
• Straw. This type of briquettes is considered the cheapest. It is also distinguished by the lowest amount of heat produced during combustion. At the same time, straw briquettes produce a lot of ash, which makes them a “cheap and cheerful” option.
• Peat. Such fuel cells have average energy efficiency, but during combustion they emit the largest amount of soot compared to other types of briquettes. In addition, peat briquettes can only be used in special ovens, which limits their scope of application.

Thus, the best option for use in the oven is briquettes based on wood waste or husks.

The main advantages and disadvantages of briquettes

The feasibility of replacing traditional firewood with briquettes can be explained by the following factors:

• The efficiency of briquettes is approximately 2 times higher than that of firewood. Also, the burning process of briquettes lasts longer due to their high density.
• Fuel briquettes take up less space compared to a similar supply of firewood.
• The combustion of briquettes is more uniform due to the uniform structure of the material.
• Even not the best briquettes produce less soot than average firewood. At the same time, they burn almost completely, leaving a minimum of ash.
• Almost all types of fuel briquettes are made from some kind of waste, which may appeal to people who care about the environment.

It would be unfair not to note some of the disadvantages of this type of fuel:

• Higher cost compared to firewood.
• The need to comply with storage conditions. In particular, the briquette may collapse when exposed to moisture.
• The quality of a briquette is difficult to determine by appearance. It happens that non-wood waste is added to wood types, which increases the volume of the material, but reduces its energy properties.
