The Storm Approach to Coal Pulverizer Optimization
raw coal top size, 7% moisture and produces pulverized coal that is 70% passing 200 mesh fineness (red line). This is pretty standard. Now, take that same pulverizer and provide fuel that is 40 HGI, still ¾" top size and still 7% moisture, but increase the fineness requirement to 80% passing a 200 mesh sieve.

Pulverized coal-fired boiler - Wikipedia
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.
