Presentation: Methods of processing off-grade wood, timber and agricultural waste

We offer to Your attention a video presentation "Methods of processing off-grade wood, waste of timber and agricultural industries". You will get acquainted with different methods of charcoal production, as well as their advantages and disadvantages.

Charcoal production in today's conditions

Unique characteristics of charcoal allow using it in various fields. Just recently it hasn’t been used commonly, but today it draws more and more attention. It suits perfectly for domestic use – chargrills, fireplaces, barbeques – as it is smokeless and environmentally friendly. 

Cyclones and multicyclones

Cyclones represent filtering units, which are used for cleaning gas and air from liquid and solid particles and from dust. The basis of this design is the principle of use of centrifugal force.

The recycling of wood waste

Wood waste recycling is a significant problem of the enterprises of logging and woodworking industries. About 25% of the biomass remains in the forest during the process of timber harvesting. The emergence of waste in form of sawdust and shavings are also unavoidable in the processing of timber. This implies that a large amount of raw materials are used unprofitable.

The stages of the activation process of coal

The production of activated carbon is quite a long process that consists of several consecutive stages. The first stage is carbonization. The process of carbonization involves heat treatment of raw materials in the vacuum inert atmosphere along with using high temperature. 

The principle of the pyrolysis technology

Accumulated industrial experience and held in the laboratory studies gave the possibility to identify several relationships that determine the influence of various factors on the pyrolysis process and the relationship between the chemical composition of wood and products of its thermal decomposition. 

Production of activated carbon

Active or activated charcoal is a group of carbon sorbents, which are produced in the industry and have standard indicators of quality.

Production and use of charcoal

Charcoal is a product obtained by wood burning in kilns, furnaces and pits without oxygen or with its small percentage. The weight of one cubic meter of charcoal depends on wood type (fir tree, birch, oak, beech). The density of charcoal depends on the wood species. 

Pellets: advantages of its using

Pellets are biofuels, derived from peat, wood waste or agricultural waste. In appearance, they are cylindrical pellets of standard size. This type of fuel has been produced since 1947. As raw materials for its production there were used: peat, low-quality wood and wood waste (bark, sawdust, chip and other logging waste), and agricultural waste.

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.
