What is charcoal? How is it made?
(1) the kiln, with mud kiln, filled with wood burning from the kiln door or door, the carbonization of wood in the kiln, volatiles escape and residual charcoal;(2) dry distillation, the distillation of wood. According to a quenching method of kiln, there are two kinds of black and white.
Charcoal (charcoal) is wood or wood raw material after incomplete combustion or pyrolysis under the condition of air isolation, dark brown or black porous solid fuel residue. Keep the amorphous carbon tar residue of impure wood hole of the original structure and now still life. In addition to the fuel, is used in metal smelting, light industry food and fuel, reducing agent of metal smelting, refining as a covering agent for protecting the metal from oxidation. In the chemical industry often carbon disulfide and active carbon materials. As a biscuit factory, smelter and other fuels, is also used for filtration, liquid water decolorization. The still grinding and painting, cosmetic, medicine, carburizing, powder alloy preparation method has two kinds of application:
Brief introduction: the form and structure of kiln kiln, Zhejiang kiln, kiln, such as carp, Hunan wood wood gourd kiln kiln and Sichuan kiln, fast iron wood kiln, kiln machine and so on. Usually in the method called the kiln kiln stuffy flameout flameout method by carbon, known as black carbon when. The wood in a kiln charring, while hot Bachu from the kiln, and then use the method of wet sand flameout, called kiln flameout method. In flameout process, and burning charcoal and carbon contact air, external oxidation, generation of white ash attached on the charcoal, known as the "white" white hair. Than hard.
