pulverized coal, and we faced difficulties in discharging biomass particles from the mill and in ensuring biomass ignition stability and high combustion efficiency. In order to improve biomass particle discharge from the mill, the velocity of conveying air flow (i.e., primary air flow) in the mill is increased by increasing the primary air flow ...

Pulverizers (coal pulverizer) are used to pulverize pieces of coal into fine particles (100μm) before placing into a boiler, to ensure efficient combustion. Pulverizers have three functions, pulverization, drying and classification. The classification function plays the important role of ensuring that only fine particles of the pulverized coal ...

Low grade coal accounts for half of all coal resources in the world, and super-high-moisture coal with a moisture content exceeding 50% is one such kind. When such super-high-moisture coal is applied to conventional USC boilers, the shortage of mill dryin
