Combustion of Coal Without Grates. Wilfrid Francis, Martin C. Peters, in Fuels and Fuel Technology (Second Edition), 1980 (b) Central or Bin System Pulverized fuel is removed from the air stream by cyclone separators. The powder can be delivered to outside users, or used locally, e.g. conveyed by screw-type conveyors direct to primary air stream of burners.
Boilers. To efficiently combust coal, it needs to be pulverized into fine particles (100μm) before being placed in a boiler. A pulverizer (coal pulverizer) is installed for this purpose, and pulverizes pieces of coal several centimeters in diameter down to fine particles. The pulverizer includes pulverization, drying and classification functions.
