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 ...
Coil Pulverizers for Boilers brighthubengineering. Ball tube mills are either pressurized or suction type In the pressurized type the hot primary air is used for drying the coal and to transport the milled coal to the furnace In this type leakage in the mill area is high In the suction type the exhauster is used for lifting the milled coal from the pulverizer to the furnace through a cyclone
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.
