Timber merchants have no place, where to put waste. Maybe they can process it into the charcoal or load it into the blast furnace, as it used to be earlier. Environmentalists with the Kyoto Protocol also do not mind...
Fuel briquette - it is a kind of solid fuel. In modern conditions when exhaustible fuel types are becoming less, a very important point is the search for new more available and efficient sources of energy. More and more people began to turn to renewable energy, because it saves money and is a new stage in the development of production as a whole.
Wood pyrolysis is the first stage of wood combustion. Flames on burning wood are formed not by combustion of the carbon in the wood, but due to gases, which are the volatile products of pyrolysis.This stage represents the decomposition of wood by heating to 450-500°C without air access. In the pyrolysis process many different substances are produced.
Activated (active) coal is carbon sorbents, produced industrially. Active carbons have standardized quality indicators. The sorption capacity, specific area of pores of activated carbon, particle sizes and a number of other indicators are specified by the Standards or Production Specifications.
The main product produced by charcoal kiln is charcoal. Charcoal is widely used in various industries: in the manufacture of building materials, in the household for space heating, for kindling fireplaces and barbecues, and in the medicine.
In this article we will discuss main types of dryers and will show you operation principles of different plants.
At the present, no more than 5% of total charcoal produced in the world is made by environmentally friendly, technological and safe methods, which correspond to modern requirements. The rest amount is produced by primitive, prehistoric way: in the pits, in heaps and by using simple charcoal kilns, which operate on the same principle.
Receiving charcoal from wood byan impact of high temperature isone of the oldest technologies.
In modern conditions it is necessary to have well-organised, environmentally friendly production, which is able to meet the needs of big companies and people.
Waste, which is going to thermocatalytic neutralization, burns in the fire chamber of thermocatalytic unit on a special fire-grate, under which hot air supplies continuously. Heating and maintaining of necessary temperature in the kiln is carried out with a help of liquid-fuel burner by using diesel oil. Usually, fuel burner is used only for primary kiln heating or for burning of low-calorific waste with high humidity.
Coconut shells are important raw materials widely used for obtaining charcoal in the world, basically in the developing countries such as Indonesia, India, Malaysia. Coconut shell charcoal is used in many areas because of its advantages and important characteristics. Moreover, coconut shell charcoal could be powdered and used for producing granular activated carbon. Due to pleasant smell, coconut charcoal is recognized as one of the best fuels for cooking.
