Explanation

peat coal is also called peat. It is a loose deposit formed in marshes, formed by plant remains through biological changes and physical chemistry changes. peat coal is the lowest degree of coalification in coal, and also the most primitive state. In natural state, peat coal is in block shape, and its water content is usually between 80% and 90%. After natural drying, the moisture content is generally between 35% and 45%, the organic matter content is between 30% and 90%, and the ash content is between 10% and 70%. Inorganics are mainly clay, quartze, etc. peat coal has fibrous or granular structure, and its color can be black, brown, brown, etc. It is porosity and porous, with a density of 1.20g/cm 3 To 1.60g/cm 3 Between. peat coal can be used as low calorific value fuel. Due to its high organic matter and humic acid composition, light weight, and good ventilation performance, it can be used as a good cultivation substrate and soil conditioner. In addition, peat coal can also be used as raw material for manufacturing building materials and light thermal insulation materials. The purified humic acid and its salts can be used to produce dye or dyestuffc, coatings, ion exchanger, foam stabilizer, accumulator negative plate expander, yeast stimulant, boiler scale inhibitor, drilling mud, concrete conditioner, etc. peat coal is distributed in Northeast China, Hebei, Henan, Shandong, Sichuan, Yunnan, Guangdong, Hainan and other places.
