Pulverized coal to 150-200mesh and sprayed into the furnace can burn more fully. Impurities can be effectively removed in the grinding process, and the burnout rate is higher. (1) Grinding Stage: Moist coal should be dried first, and then sent to the main grinding room for grinding.
Fuels to be used in pulverized coal-fueled boilers must be previously reduced to a particle size smaller than 75 μm, so, by analogy, to use biomass in cofiring with coal in a pulverized coal boiler it must be ground to similar sizes. However, the grinding of biomass is a very energy intensive process due to the fibrous structure and the ...
