A pulverized coal-fired boiler is an industrial or utility boiler that generates thermal energy by burning pulverized coal (also known as powdered coal or coal dust since it is as fine as face powder in cosmetic makeup) that is blown into the firebox.. The basic idea of a firing system using pulverised fuel is to use the whole volume of the furnace for the combustion of solid fuels.
2. High mill coal spillage 3. Low pulverized fuel fineness 4. Mill fire 5. Low capacity of mill . 3.2.3 Raw Coal Feeders . The purpose of a RC feeder in the coal pulverizing circuit is to feed the raw coal from the bunker into the pulverizer in controlled and varied quantities corresponding to the boiler load demand.

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.
2016-5-3 The point we are trying to make is this: coal pulverizer capacity is a specified fuel grinding capability or throughput at a certain HGI (coal grindability index) and also based on raw coal size, moisture and desired fineness level. These factors are significant and must all be taken into. More
