Bowl Mill Raw Coal Pulverizers platerialopez

Coal Mill Pulverizer In Thermal Power Plants. 10.Bowl mill bowl mills are employed to pulverize the pre-crushed raw coal to the required fineness before it is admitted into the boiler furnace for combustion.The mill output can be easily varied, as per the turndown ratio from its minimum to maximum load.Crushed raw coal at a controlled rate is fed into the revolving bowl of the bowl mill.

Raw Coal Spillage Or “Pyriting”

Coal dribble or spillage is raw coal that is rejected through the pulverizer’s pyrite discharge. This is caused when the velocity across the pulverizer throat is too low to maintain suspension of coal. Air velocities through the pulverizer throat should be 7,000 to 7,500 Fpm when calculated on a free jet basis.
