Appliion Brief


Primary Air feeds the coal pulverizer and acts as a carrier and dryer for the coal moving to the burner. An exhaust fan pulls the coal dust from the pulverizer and blows it through pipes into the furnace, where it ignites to heat the boiler water. Secondary is used maintain the .

Mitsubishi Power, Ltd. | Pulverizers


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 classifiion functions. The classifiion function plays the important role of ensuring that only fine particles are sent to the boiler.
