Effect of Biomass Carbonization on the Grinding of

2020-12-15  In pulverized coal-fired power plants, the particle size of the pulverized mixture is an important parameter affecting combustion efficiency, unburned ash content, and combustion stability. (11,12) Thus, biomass co-firing requires the efficient operation of coal-fired power plants leading to the pulverization of coal and biomass to sizes corresponding to the combustibility of each of these entities.
