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.

Question 2 of 15. 2. The smaller the piece of coal, the more efficiently it will burn -- so it's no surprise that a lot of work has to be done to get the coal ready for the boiler. Chunks of coal are first run through a crusher and then through a pulverizer, where they are ground to a powder the consistency of flour.
