In general, fluidized bed boilers can substitute higher levels of coal with biomass than pulverized coal-fired or grate-fired boilers. Fluidized bed boilers can handle biomass with higher moisture content (10%–50% instead of <25%) and larger particle sizes (<72 mm instead of <6 mm) than pulverized boilers (Agbor et al., 2014). They can

Boilers. To efficiently combust coal, it needs to be pulverized into fine particles (100μm) before being placed in a boiler. A pulverizer (coal pulverizer) is installed for this purpose, and pulverizes pieces of coal several centimeters in diameter down to fine particles. The pulverizer includes pulverization, drying and classification functions.
