What kind of coal is good for chain boiler?
27 Aug 2021
Chain grate has certain selectivity for coal types, and soft coal with volatile content above 15%, ash melting point above 1250℃, moderate particle size and calorific value above 18800~21000kJ/kg is more suitable.
The ash content in coal should be controlled at 10%~30%. The pulverized coal (0~6mm) should not exceed 50%~55%, the pulverized coal of 0~3mm should not exceed 30%, and the lump coal size should not exceed 40mm.
