Areas of briquettes application

Today wood briquettes are universal and one of the most economical types of fuel of the XXI century. This practical, effective and environmentally clean fuel has been a successful abroad for more than 20 years, and every year the demand for it is only growing.

Wood-working waste and non-standard timber can be real money!

When we lose money, we are getting upset. Also it is hard to imagine a situation when we throw out our earnings. As a result of deforestation, a lot of non-standart timber is formed (branches, knots, stumps, roots and so on). This type of wood brings a  lot of problems to their owners, especially in gasified regions.

 

Fuel briquettes are preferable to firewood

In Europe the use of wood briquettes is becoming more popular every year. The process of pressing finely crushed dry wood waste (sawdust, chips, bark) is the basic technology of wood fuel briquettes production. The briquettes have cylindrical or rectangular shape and weight from 500 grams to 2 kg. 

Charcoal production

Charcoal production is the oldest technology of mankind. It is charcoal initiated the development of civilization. The charcoal demand has grown, so it is now produced by many manufacturers. Environmentally friendly and cost-efficient installations are designed and implemented. Any technology, if it is developed correctly, will be environmentally friendly and energy efficient.

The role of lignin in the production of briquettes

The lignin is a part of the wood, which acts as a natural binding material during the pressing process and makes the briquettes dense. Hardwood may contain from 20% to 30% of lignin, softwood - up to 50%. Under the influence of very high pressure during briquetting, the temperature of the source material (wood or agricultural waste) increases and this leads to the release of lignin.

Charcoal and its types

Charcoal is solid porous highcarbon material, which formed by wood heating with low access of air (or without air at all) in kilns or retorts. Heat of combustion of charcoal is equal to 30000-35000 kJ/kg (or 7000-8100 kcal/kg). Significant porousness of charcoal determines his high adsorption qualities. 

Wood pyrolysis (dry distillation of wood)

Wood pyrolysis (dry distillation of wood) is a decomposition of wood under the heating up to 450 oC without access for air and by the producing of gaseous and liquid (including wood resin) products and also solid residue – charcoal. Dry distillation of wood is one of the first processes of chemical technology. Since XII it was widely used in Russia to produce the pine-tree resin (that is used to tar wooden vessels and for rope saturation); this trade was called tar extraction.

Pyrolysis. Types of pyrolysis.

Pyrolysis is a process of thermal decomposition of industrial waste by its partial burning or direct contact with end product of fuel combustion. This method is used for neutralization of most wastes including “inconvenient” ones for burning or gasification: viscous and paste-like wastes, wet sediments, plastic, slime containing large quantity of ash, soil polluted with residual fuel, oils and other compounds and dust-forming waste. 

Biofuel production is a promising activity direction

Due to increase of prices for traditional energy sources, the use of biofuel for domestic and industrial purposes is becoming more and more rational. Pellets and wood briquettes are popular in Europe since the beginning of 21st century. Pellets and briquettes are popular in Europe since the beginning of 21st century. Currently, the volumes of supply and consumption of this fuel in Europe is about 400 million tons per year.

Ğœedical waste

Ğœedical waste (ĞœW) are factors of direct and indirect risk of environment pollution, emerging civil contagious and non-contagious diseases. World Health Organization (WHO) reckons MW to be hazardous and recommends special services for processing to be created. Majority (according to various authors from 60 to 85%) of medical prophylaxis institution (MPI) waste is non-hazardous and can be reckoned to be classified as solid domestic waste (SDW).
