What are the types of charcoal?
1. What are the types of charcoal?
coal is often called, but in fact coal and charcoal are two substances. coal is an ancient plant buried in the ground. The solid combustible minerals have gradually formed by complex changes. Carbon is a porous substance, carbon burning and coal.The principle of formation is similar, and the substance left by the wood after decomposing the organic matter under high temperature and hypoxia.There are four main types of charcoal:
1. charcoal: It is a dark brown or black polyitic solid fuel that is residual under the condition of isolation of the air under the condition of isolation of the air.
2. Coke: Under the condition of isolation of the air, it is heated to 950-1050 C. It is finally obtained by drying, heat solution, melting, bonding, curing, contraction, etc.
3. activated carbon: It is a series of processes such as charcoal, bamboo charcoal, various fruit shells, and high -quality coal through physical and chemical methods to make raw materials crushed, sieved, catalyst activation, rinsing, drying and screening and other processes processing and manufacturingAdsorption agent.
4. Carbon black: It is a kind of light, loose and extremely thin black powder with large surface area and is a product of natural gas, heavy oil, fuel oil, etc. under the condition of insufficient air.It is a kind of non -fixed carbon.
How to make charcoal
There are three main methods for making charcoal:
1. Kiln burning method
The kiln burning method is a method of burning charcoal with charcoal kiln. It uses soil to build kiln and fills wood. Burning from the kiln door or fire door, so that the wood can be carbonized in the kiln.
2. Stemming method
Wood dry distillation is to place the wood in a dry distillation kiln. The process of heating and decomposing charcoal under the condition of isolation of the air, putting the wood in the dry distillation kiln, heating and decomposition under the conditions of isolation of the air;Wooden gas can condense wood (caramel and caramel acid; the remaining solid is charcoal.
3. Carbon mechanism charcoal method
The charcoal machine is a machine that crushes raw materials such as bamboo and wooden sawdust, Peanut shells, corn sticks to a granular shape within 10mm. After drying the dryer, put it in a charcoal furnace for carbonized machines., Two -raw material waste use for charcoal.[The process of charcoal mechanism charcoal & gt; & gt;]
