What is lean coal, lean coal classification
(2) lean coal (PM). Coal is a high degree of coalification coal, non caking or slight adhesion. No coking coking furnace. In the laminar flame, burning resistance.(3) lean coal (PS). Lean coal is a kind of high rank and low volatile bituminous coal and weakly caking. Typical coal coking, coking, coke powder are generated.(4) (SM). Coal coal is low volatile medium caking coking coal. Can produce a certain amount of colloid in coking. Separate coking, can get large blocks, crack less, shatter resistant better coke, but poor wear resistance of coke.
(1) anthracite (WY). The carbon content of high volatile anthracite, low yield, high density, high hardness, high ignition temperature, combustion not smoke.01 anthracite for old anthracite anthracite for typical 02; Anthracite; No. 03 anthracite for the young. Such as Beijing, Jincheng and Yangquan were 01, 02 No. 03, anthracite.
Coal: coal soot level top coal, it is characterized by a higher ignition temperature (350 - 360 DEG C), high calorific value, weak bond or not. Coal is mainly used for power generation and power plant boiler fuel. The use of coal, and the other with the use of high volatile coal does not lose for a a good way.
