In pulverization, biomass has poor grindability owing to its fibrous structure, which increases the power consumption and deteriorates the coal grindability if co-milled [ 3 ]. This can also cause poor burnout of char, which leads to a high unburned carbon (UBC) content in the ash from a large utility boiler adopting pulverized fuel combustion.

01.08.2017Note that because the Young's moduli of coal and mineral substances differ, iron-based minerals are more difficult to pulverize and often remain in the bottom residue of the pulverization system. As the particle sizes decreased, the elastic deformation of particles weakened the pulverization impact.
