What are fuel briquettes. Comparison of firewood and wood briquettes - which is better and more profitable. Prices for Eurowood Briquettes

The main prerogative of the owner of a country house is to provide his household with maximum comfort.

And, as you know, warm comfort is achieved through the use of a heating system with an efficient heating boiler. Therefore, a good owner, first of all, thinks about what type of fuel to use in the boiler in order to achieve maximum heat transfer.

The modern fuel materials market is very widely saturated with offers to purchase various kinds fuel, the energy efficiency of some could be argued. We propose to consider such a type of raw material for the furnace in the boiler as fuel briquettes Ruf, which today are the leader among other types of fuel.

What are

The fuel material of the German brand Ruf is briquettes, which consist of sawdust and waste of high-quality wood, both hard and soft, while the bark and other illiquid assets of the forest industry are not included in the composition.

It is also important that Ruf fuel briquettes contain absolutely no chemical substances on an adhesive basis. First of all, this is due to the technology of making briquettes on a special set of technical devices.

What equipment are they made on?

The technological line for the production of Eurobriquettes Ruf consists of two important structural elements:

• dryer, which is designed to reduce the moisture content of wood chips and sawdust;
• a hydraulic press that directly briquettes the wood material.

result technological process will be briquettes, shaped like a standard brick.

What are the characteristics of

The technical properties of Ruf fuel briquettes are as follows:

• calorific value ranges from 4200 to 4500 kcal/kg;
• the maximum ash content is 1%;
• humidity is in the range of 7–13%;
• the average density of briquettes is 750–800 kg/m3.

The numerical expression of the above characteristics of Ruf fuel briquettes will probably not tell anything to an ordinary person.

To understand the effectiveness of using briquettes of this trademark, let's compare some properties of other types of fuel according to the same indicators:

1. Calorific value:

• brown coal - 3910 kcal / kg;
• wood - from 1500 to 3000 kcal / kg, depending on humidity;
• coal - 4800 kcal / kg;
• briquettes Ruf - an average of 4350 kcal / kg.

• brown coal - 40%;
• peat briquettes - 16%;
• hard coal - 20%;
• briquettes Ruf - 1%.

It is enough to compare two indicators to understand one simple truth: Ruf briquettes are very efficient view fuel for a heating boiler of a country household!

Benefits of using

Analyzing the above worthy characteristics of Ruf fuel briquettes, it is logical to assume that their use has a number of the following advantages:

• in the process of burning, the briquettes do not have a characteristic crackle, and also do not sparkle;
• have a high degree of heat transfer during prolonged combustion;
• excellent resistance to moisture;
• practicality in use;
• with a uniform investment in the furnace of briquettes and firewood, the heat transfer of the boiler is significantly increased, and the consumption of fuel materials is reduced by 2-4 times;
• briquettes, which contain birch wood, do not leave carbon deposits and tar scale on the walls of the fuel chamber of the boiler, which greatly facilitates the maintenance of this boiler unit;
• occupy a small amount of space during storage, while the cleanliness in the warehouse will be guaranteed.

The above advantages of Ruf fuel briquettes can only say that this is the best type of fuel for a heating boiler in a country house. And in conclusion of the article I would like to dwell on one more aspect.

As you know, transportation costs for the delivery of fuel are logically included in its cost. And now let's give an example: a truck with a body volume of 80 m3 at a time can transport 7-8 tons of firewood with dense packing, at the same time, it can deliver 20-24 tons of Ruf fuel briquettes! Draw your own conclusions!

Thus, in this article we have indicated all the important aspects of using fuel briquettes of the Ruf brand. We hope that our strong arguments will cause you to use only Ruf fuel briquettes to heat your home.

How to choose a quality RUF briquette, see the following video:

Fuel briquette is an alternative material that allows you to quickly and efficiently kindle a stove or fireplace and warm up the room. However, 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. In addition, you can even organize your own business.

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

3. The minimum amount of smoke, sparks.

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

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

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

7. Easy storage. The presented material does not take up much space, it can be 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. Unpretentiousness in storage.

Applications 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, catering establishments.

In addition, fuel briquettes can be used in warehouses where wood materials are dried and stored. Industrial enterprises the presented type of fuel is also often used in combination with other materials. In any case, the presented material is the most efficient and economical, 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 source material and equipment. First, let's figure out what the product can be made of. So, wood and plant waste is most often used in production.

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

Naturally, for the production you will also need water, clay and other substances that can glue the raw materials together. In some cases starch may be added. In general, you can use for the manufacture of briquettes any combustible garbage that lies uselessly on your territory.

Applied equipment

In order to make a fuel briquette with your own hands, you need to choose the right press or chipper. When choosing a press, it is necessary to decide what shape and area the elements will have. Most often, round and rectangular briquettes are made.

Among the professional equipment, one can single out a screw, shock-mechanical and hydraulic press. The first apparatus is capable of producing octagonal elements with a small hole in the center. They are characterized by maximum density, therefore, they provide the highest burning time. produces rectangular elements with the smallest density, which ensures high material consumption. Making fuel briquettes at home using a shock-mechanical device gives you the opportunity to make material of any shape. At the same time, 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 to produce the elements.

2. Dry clay should be added to the same container, which will serve as a 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 be well molded. 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 gruel. After that, the resulting products must be thoroughly dried in the sun. In order for them to be durable, each element should be overlaid with paper or rags. After complete drying, all briquettes can be put together.

When you press the raw material with a press, you will have to put in a lot of effort to squeeze as much water out of the mixture as possible.

Do-it-yourself production of fuel briquettes is quite simple, although laborious. Please note that the humidity of each product should not exceed 13%. In order for the element to burn better, paper can be added during manufacture, which must be torn into small pieces. And so that all the constituent parts stick together better, a little starch can be added to the mixture.

Please note that for different types of heating appliances you will need different briquettes. For example, peat and birch elements are well suited for fireplaces. For barbecues, it is better to use eurofirewood or wood briquettes. They can both burn and 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!

Such fuels as firewood and coal are more and more confidently replacing heating briquettes, for the manufacture of which waste from the food, light and woodworking industries is used. Both from an economic and environmental point of view, pressed briquettes are much more profitable, because at a very affordable price, they have very high energy efficiency and emit a minimum of carbon dioxide. Depending on the type of waste, briquettes are wood, coal, peat and pressed from sunflower husks.

Comparative characteristics of briquettes

Each type of briquettes has its own characteristics and advantages. And although they are all great for heating in living conditions However, it is worth familiarizing yourself with their characteristics in more detail in order to choose the best option.

This type of briquettes is obtained by pressing various wood waste - deadwood, sawdust, shavings, substandard wood. Before pressing, the waste is heated to a certain temperature, as a result of which an adhesive substance, lignin, is released from the cells. Thanks to lignin, briquettes acquire high strength and retain their shape during transportation and storage.

The advantages of briquettes over solid wood are obvious:

In addition, wood briquettes have other advantages:

• pressed wood does not spark during combustion and emits very little smoke;
• the boiler is maintained at a constant temperature;
• briquette burning time 4 hours;
• the remaining coals after combustion are great for cooking on an open fire;
• the correct form of briquettes simplifies their transportation and storage.

Such fuel is sold not in cubic meters, like wood, but in kilograms, which is much more profitable.

This type of briquettes is obtained from the elimination of hard coal. The screenings are first crushed, mixed with a binder, and then pressed under high pressure.

The main properties of such fuel:

• coal briquettes do not smoke;
• do not emit carbon monoxide;
• burning time in conventional boilers from 5 to 7 hours, with adjustable air supply - 10 hours;
• suitable for domestic use;
• have a compact shape;
• during combustion, 5200k / cal is released and a constant temperature is maintained;
• maximum ash volume - 28%;
• have a long shelf life.

Coal briquettes are the most optimal fuel in severe winters, when due to low temperatures in household pressure drops. Briquettes burn at any temperature, the main thing is that there is a constant flow of air.

To make briquettes, peat is dried, heated and pressed under high pressure. The result is neat light bricks of dark color. With adjustable air supply, peat briquettes maintain the temperature for 10 hours, which is very convenient for heating the house at night.

Basic properties:

The ash that remains after the combustion of fuel can be used as an effective lime and phosphate fertilizer. For many owners of private households, this factor is decisive when choosing heating briquettes. Since peat is a flammable substance, it should be stored at a safe distance from open flames and heating appliances. Even dust spilling out of the packaging can ignite and cause a fire, so you need to handle the briquettes correctly.

Sunflower husks, buckwheat and rice husks, rye, oat waste and even straw are widely used to make fuel briquettes. The most common are briquettes from sunflower husks, since a large percentage of waste remains in the production of oil. The maximum humidity of the pressing husk is 8%, which increases the heat transfer and reduces the ignition time.

Specifications:

• the density of briquettes is 1.2 t/m³;
• heat transfer - 5200 kcal / kg;
• the volume of ash is from 2.7 to 4.5%.

Additional benefits:

• no harmful impurities;
• affordable price;
• long burning time;
• ease of storage and transportation.

Comparison of the characteristics of heating briquettes and fuel shows that pressed materials are still more efficient. If you choose between the briquettes themselves, you should take into account their features and properties.

To less often lay fuel, you should purchase coal or peat briquettes; if ash is required for fertilizer, the best choice there will be wood briquettes and from the husk. They are also the most affordable. And in order to better determine, it is recommended to buy a small package of each type. This will help to accurately assess the strength of the briquettes, the duration of burning, the amount of heat generated and make the best choice.

Pressing is carried out on hydraulic press at a pressure of 10-15 MPa with a diameter of elements of 10-40 mm. The briquette is dried at a temperature of about 50° C. until it reaches a constant weight. 2 s.p. f-ly. 1 tab.

The invention relates to the field of carbon-containing fuel technology, in particular to a composition for fuel briquettes (TB), which can be used as a household fuel in fireplaces, car furnaces, domestic boilers, and also as a splinter for ignition. The main requirement for fuel briquettes is a sufficiently high level of heat-technical and physical-technical characteristics. The heat-technical characteristics include the specific heat of combustion Q p n i.e. the amount of heat released during the combustion of 1 kg of fuel, however, the heat of combustion depends on the rate of combustion, i.e. with faster combustion of fuel briquettes with a certain calorific value per unit time, much more energy is released needed for heating, thus, the combustion time of fuel briquettes is of no small importance when used for various purposes. One of the important indicators of the operation of fuel tanks is their mechanical strength, with insufficient strength, destruction occurs, which leads to significant losses during loading and unloading operations, as well as pollution. environment due to dust. The composition of fuel briquettes based on milled peat is known in industry, which is an element dried and pressed in 2 stamp peat presses at a pressure of 80-120.0 MPa. There are peat briquettes from milled peat 80-70% and lump peat 20-30 % Known peat briquette, including peat and carbonaceous material, which is screenings charcoal, petroleum coke or mixtures thereof following ratio ingredients, wt. peat 50-90, screenings of charcoal, petroleum coke or their mixtures 10-50% Peat briquettes are distinguished by low mechanical strength, high crumbling, poor flammability and low calorific value (3500-3800 kcal/kg). A known method for producing fuel briquettes, including dosing, grinding, screening, drying, mixing, pressing peat, brown coal and screening hard coal, in which joint dosing, mixing, preparation and drying of peat with brown coal, and coal screenings are crushed and dried separately, after which they are dosed and mixed with lignite composition, and then the resulting mixture is pressed. This method is the closest analogue to the method for producing fuel briquettes. Fuel briquettes obtained by this method have insufficient strength. The objective of the invention is to increase the mechanical strength, flammability and calorific value of fuel briquettes, as well as the disposal of obsolete pyroxylin powders. The task is achieved by the fact that the composition for fuel briquettes, including peat and technological additives, as a technological additive contains nitrocellulose pyroxylin powder crushed to a size of not more than 3 mm and slurry waste from the production of dioctyl phthalate, in the form of a mechanical mixture of plasticizer-dioctyl phthalate, activated carbon and clay "Butron", containing dioctylphthalate 36 10% and solid components 64 10 wt. with the following content of components, wt. Powder crumbs obsolete pyroxylin powders 10 25 Peat 40 50 Sludge 30.50 amount of 10-15 wt. while pressing is carried out on a hydraulic press at a pressure of 10-15 MPa with a diameter of elements of 10-40 mm, and drying is carried out at a temperature of about 50 o C until the briquette reaches a constant weight. As a powder crumb, outdated pyroxylin, spherical powders of any grades ("VU", "VT", 5/7, 6/7, 12/7, 14/1 SF 033, etc.) can be used, which are pre-crushed on conical mills to a particle size of not more than 3 mm. Pyroxylin gunpowder has a calorific value of 900 kcal / kg and burns out in a short time with the release of a large number fuel. In this regard, the introduction of gunpowder into the composition improves the flammability and combustion of fuel briquettes (see table). Peat is a combustible mineral, sludge is a waste from the production of dioctyl phthalate, is a mechanical mixture of plasticizer-dioctyl phthalate, activated carbon and Butron clay. The introduction of sludge into TB improves their mechanical strength (see table). Technology system obtaining fuel briquettes. one). Preparation of components, grinding of gunpowder, dispersion of peat on a sieve. 2). Mixing the components in a paddle-type mixer for 30 minutes using ethyl acetate as a solvent in an amount of 10-15% (over 100%). 3). Pressing on a hydraulic press, pressure 10-15 MPa, elements with a diameter of 10-40 mm. four). Cutting to the required length (20 cm). 5). Drying at 50° C. to constant weight. Possibility of obtaining fuel briquettes this composition seen from the following examples. Example 1. Peat, previously crushed and sifted, powder crumb and sludge were loaded into a paddle mixer in the amount of: 20 kg of powder crumb, 50 kg of peat and 30 kg of sludge, mixed for 30 minutes. using a solvent of ethyl acetate in an amount of 10 kg. After mixing, pressing was carried out on a hydraulic press with a pressure of 10-11 MPa of the elements, and then drying at 50 o C to a constant weight. Examples 2-8 were performed analogously to example 1, changing the ratio of components and pressing pressure. The composition and test results of the samples are given in the table. The use of this technical solution will make it possible to obtain a composition for fuel briquettes with a high mechanical strength, lower ash content during combustion, higher calorific value, and will also allow the use of obsolete pyroxylin gunpowder.

What are kiln briquettes?

Briquettes for the furnace or eurofirewood, as they are sometimes called, are compressed products of the processing of various materials. In the process of processing raw materials under the action of high pressure, more moisture comes out of it. Due to this, the finished product is characterized by low humidity and high calorific value.

Composition of briquettes

The materials for the manufacture of eurofirewood are usually various tree species, straw, cereal or seed husks, peat and coal. Let's consider them in more detail.

Kinds

The method of processing raw materials plays an important role. I take into account the manufacturing process, briquettes can be divided:

• Piny-kay. Fuel having the highest density of 1.40 g/cm3. Behind the form they are similar to a cube or a hexagon, which has a hole in the middle. Due to the air inside the recess, even combustion is ensured.
• Products of low density - 0.8 g/cm3. These are squares or rectangles made from the smallest particles of material. Differ in high heat conductivity and long burning. Easy to store, transport, do not take up much space.
• Products from large sawdust with an average density. Their disadvantages can be considered rapid combustion, frequent loss of shape and deformation. Due to low production costs, they have a relatively low price.

Advantages and disadvantages

Heating with an alternative type of fuel has its positive and negative sides.

Pros:

• High calorific value and heat transfer. These figures are significantly higher for alternative fuels than for conventional logs.
• Long burning time. Therefore, their consumption is much less than that of firewood or coal.
• Uniform combustion. Briquettes burn without unnecessary noise and smoke. And ashes form less than coal or firewood. This simplifies the cleaning of the furnace device after their use.
• Slight emission of resinous substances. Thanks to this, the chimney does not clog.
• Long shelf life. Briquettes can be stored from 1 to 5 years (depending on the production).
• Environmental friendliness. The product is natural, without various impurities. Safe for people and the environment.

Minuses:

• Prices for briquette fuel are higher. Firewood is much cheaper. But thanks to economical consumption, the costs pay off.
• The acquisition of such goods in some cities or towns is difficult.
• Store products in accordance with the instructions. Therefore, a clean and dry place should be prepared.
• The ash emits a pungent odor.

Briquettes or firewood?

Although eurofirewood is usually made from wood waste, they are completely different in characteristics. Eurowood is aesthetic and easy to store and use. They burn slowly and give more heat. But the amount of heat from briquettes is much less than from firewood.

Therefore, it will take a little longer to heat the house in severe frosts than with wood heating. And this brings some inconvenience. The ash content of the alternative fuel is low.

But their ashes have a pungent odor that others may not like. Briquettes do not create aesthetic pleasure, because they burn without noise and crackling. Using firewood is much more pleasant: you can make a cozy atmosphere.

What is better to heat the stove with wood or briquettes? There is no single answer to this question. The optimal home heating scheme: burning both types of fuel (classic and alternative) at the same time.

It is better to reach the optimum temperature with the help of ordinary firewood, and then only maintain it with briquettes. The use of briquettes alone should be used for long-burning furnaces. So you save yourself from the need to constantly put a new batch of firewood.

What briquettes are better to use?

Various types of briquettes have different level calorific value. This feature should be considered when choosing a product, because it is the most important. Sawdust briquettes are considered the best option.

These fuel briquettes are better for a stove in a house, bathhouse, cottage or other room. They have high heat output, burn for a long time, leave little ash, are easy to use and transport, and do not pollute the air.

Briquettes of seed and softwood husks also have good performance, but due to the presence of oils, they pollute the chimney. As a result, the heating device will require frequent cleaning.

Before buying, pay attention to the structure and moisture content of the product. If it is deformed or crumbles when pressed, it is better to refuse such a purchase. And high humidity reduces the thermal efficiency of the product. Prefer Pini-kay fuel. It has maximum density, burns more evenly and longer.
