1. What are the types of charcoal
Coal is often called together, but in fact coal and charcoal are two substances. Coal is an ancient plant buried in the ground. A solid combustible mineral that has undergone complex changes and gradually formed, and charcoal is a porous substance. The formation principle of charcoal is similar to that of coal, which is made by decomposing wood under the condition of high temperature and lack of oxygen. substance. There are four main types of charcoal:
1. Charcoal: It is the dark brown or black porous solid fuel that remains after incomplete combustion of wood or wood raw materials, or pyrolysis in the absence of air.
2. Coke: It is the final product obtained by heating bituminous coal to 950-1050 ℃ under the condition of isolating air, after drying, pyrolysis, melting, bonding, curing, shrinking and other stages.
3. Activated carbon: charcoal, bamboo charcoal, various fruit shells and high-quality coal are used as raw materials for crushing, sieving, catalyst activation, rinsing, drying and screening of raw materials through physical and chemical methods. The adsorbent produced by a series of processes.
4. Carbon black: It is a light, loose and extremely fine black powder with a large surface area. The resulting product is essentially an amorphous carbon.
Second, how to make charcoal
There are three main ways to make charcoal:
1. Kiln burning method
Kiln burning is a method of burning charcoal in a charcoal kiln. The kiln is built with soil, filled with wood, and fired from the kiln door or fire door, so that the wood is carbonized and volatilized in the kiln. Charcoal can be obtained after the material escapes.
2. Dry distillation method
Dry distillation of wood is a process in which wood is placed in a dry distillation kiln, heated and decomposed into charcoal in the absence of air. The wood is placed in a retort kiln and heated and decomposed under the condition of isolating the air; the volatile matter that escapes cannot be condensed is wood gas, but wood tar and pyrolignoic acid can be condensed; the remaining solid is charcoal.
3. Charcoal Mechanism Charcoal Method
The charcoal machine is to grind bamboo sawdust, peanut shells, corn cobs and other raw materials into a 10mm size by a sawdust pulverizer. The granules inside are dried and formed by a dryer and put into a carbonization furnace for carbonization. [The process of charcoal mechanism >>]
