coal mill - pulveriser lube oil The pulveriser grinds the coal to dust in rotating grinding rollers and sieves, so that it can be used as fuel. The pulveriser lube oil is subjected to extreme levels of very fine particles, and many power plants believe the plant should be shut down periodically to change the oil.
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 ...

Abstract. Power plant boiler fuel demand is transmitted as a coal feeder speed demand to a coal pulverizer control. A speed controller operates the feeder in accordance with the speed demand, and a position controller for a hot coal transport air damper positions the hot air damper to hold the mill outlet temperature to a setpoint value and to increase or decrease damper position in accordance ...
The lower limit of the furnace volume is dominated by the space required for burning the fuel completely, or to an extent less than the allowable unburned fuel loss. To complete the fuel combustion within the furnace space, the fuel injected into the furnace has to reside there for a longer than critical time t r. The residence time of the combustion gas produced in the furnace can also be ...
