Branches of application of charcoal
Our company specializes in the development and manufacture of equipment for the production of charcoal from wood of various types of trees, briquettes, as well as waste from the timber processing industry and agriculture.
The main areas of application of charcoal:
1. As fuel for fireplaces, barbecues and other similar devices.
Unlike conventional fuel (for example, firewood), charcoal does not form smoke and open flames if the ignition is done correctly, but gives only the required temperature – heat, so bars and restaurants use it with pleasure in their barbecues for cooking various dishes. At the same time, there is no need to wait for the wood to burn out – after all, charcoal is a ready-made fuel. It is also important that our charcoal is also excellent as a fuel for home open fireplaces. Due to the absence of impurities and high carbon content, this charcoal burns for a long time (gives heat) and does not emit odors (smoke) into the room at all.
2. In industry.
- in ferrous and non-ferrous metallurgy as a reducing agent (charcoal has a high carbon content);
- for the production of aluminum, boron, etc .;
- in the production of pure silicon, which is used to make semiconductors;
- in the production of glass, crystal, paints, electrodes, plastics;
- obtaining in the process of pyrolysis of charcoal liquid by-products in the form of wood tar (tar), from which they are subsequently produced: turpentine, food acetic acid, rosin, methyl alcohol, alcohol solvents, etc.
3. In agriculture.
- As a feed additive in animal husbandry.
- As a fertilizer in crop production.
4. In construction.
As an insulating material in construction, as charcoal is very hygroscopic and absorbs odors well.
5. As anti-corrosive powders and lubricants.
Charcoal finds some use in instrumentation and printing, where it is used to grind and polish parts and shapes. The most suitable for these purposes is coal from softwood, obtained according to a special technological regime. In mechanical engineering, in a number of cases, solid lubricants are used, mainly graphite. Charcoal, due to its low ash and pollution content, can also be used for the production of the specified lubricant. To do this, coal is mixed with sedimentary resin, calcined at a temperature of 1400-1500 °C, and then processed with manganese-sour potassium, sulfuric acid or tannin.
6. In the production of black powder.
In the production of black powder, coal is used mainly from alder or buckthorn wood with a carbon content of 72-80%. Gunpowder prepared on the basis of coal from other types of wood is more difficult to ignite, therefore the use of other types of coal is not practiced. The rate of combustion of gunpowder is affected by the amount of coal and the carbon content in the coal. With an increase in the amount of coal, the combustion rate of the powder decreases, and with an increase in the carbon content in coal, it increases. The composition of gunpowder contains charcoal in an amount of 12 to 20%. So, hunting gunpowder contains 14-16% coal, corded powder 12%, sulfurless 20%, etc.
7. In the production of electrical coal products.
Electric coal products are made from pure carbonaceous materials such as petroleum and pitch coke, graphite, soot, charcoal, etc., by mixing with coal tar or pitch. These products are used in many sectors of the national economy. They are used in electrical equipment for various motors, in electrical machines, for thermal purposes, in electric vacuum technology, etc. This includes all types of carbon resistances, various contacts, brushes, products for technology, communications and many other items.
8. As a filter for plastics.
Charcoal can be used as a filler in plastics. Plastics of this type, where the filler is a powdered carbonaceous material, include, for example, some grades of faolite, special-purpose pressing materials, etc. In these plastics, coal can replace expensive and scarce graphite. Charcoal, as already noted, is a low-ash material, very clean in terms of the presence of impurities. It is stable in chemically aggressive environments and sufficiently heat-resistant. Raw coal has a high electrical resistivity. When coal is calcined, its electrical conductivity increases rapidly, therefore, by calcining coal to different temperatures and using some additives, it is possible to obtain products with specified dielectric properties. Calcined charcoal acquires significant adsorption activity, which enhances its main service function as a filler – adsorption strengthening of the product. This function is based on changing the mechanical properties of liquids near solid surfaces. The dissolved resin molecules near the surface of a solid coal particle are oriented under the influence of adsorption forces of attraction. The liquid around the particle acquires an ordered structure, while its mechanical properties change greatly. When solidified, this structure is retained and the physical and mechanical properties of the resulting solid are improved. In the production of irresponsible products, wastes of charcoal production can be used, i.e. coal fines and dust, which have not previously found effective use. Coal fines differ from commercial coal in a slightly higher ash content, but this circumstance can only affect the acid resistance of products, without affecting other properties. Resins such as phenol-formaldehyde, furfuraldehyde, etc. can serve as a binding element for charcoal plastics. The composition of press materials can also include wood-resin pitch, the presence of which in small amounts improves the plasticity of products.
9. As a raw material for the production of activated carbons.
Active carbons are porous carbon bodies that create, upon contact with a gaseous or liquid medium, a significant surface area for the sorption process.
Applications of active carbons:
- Chemical, food, pharmaceutical, fuel and energy, metallurgical, oil and gas production and processing industries. As well as environmental protection.
