ence in measured micron sizing. Remember that coal fineness, or particle size, directly af-fects the time required for "carbon burn-out." Improved fineness also improves fuel distri-bution to each burner line. Also observe that the variance from 60% passing 200 mesh results in a typical mean particle size of about 80 microns versus a
