Pulverizers / Mills. Reliable coal pulverizer performance is essential for sustained full-load operation of today's power plants. An effective pulverizer must be capable of handling a wide variety of coals and accommodating load swings in utility boilers as large as 1,300 MW. B&W's pulverizers, found at power stations throughout the world.

While the coal is crushed, the pulverized coal and gas are brought out of the mill by the special induced draft fan through the air cleaning coal grinding device. The thicker particles will be returned to the grinding bin through the return screw of the discharge device for re-grinding. Working Principle of Coal Mill

Coal CO2 emissions were flat during 2014-2019 (red line) despite coal generation rising 1.4% (yellow), as the chart below shows. Since coal capacity continues to increase (pink), existing coal plants are running for fewer hours (purple). On average, the world's coal plants were running around half the time in 2019, with a load factor of 53.5%.

Explosions consistently occur when the coal air mixture is leaner than normal, either when initating coal feed on mill start-up, stopping coal feed on shutdown, or when equip- ment problems cause inadvertent loss of feed. Upon loss of feed to a pulverizer, the coal/ air mixture in the system becomes leaner and the coal dust will

Coal preparation occurs in three stages: 1 crushing and sizing, or basic cleaning; (2) hydraulic separation, or standard cleaning; and (3) dense (heavy)-medium separation, or complete cleaning. Flotation is an additional process that is increasingly being used during third-stage cleaning to increase recovery and cleaning of fine coal.

The pulverised coal from a mill is transferred through alternative flue gas to the cyclone separator, where the coal is separated and flue gas is sent back to the mill. The coal is then supplied to the burner feeder from where it is mixed with primary air and supplied to the burner for the combustion. Advantages. Good control on coal fineness.
