Why pulverised coal is used?

Pulverised coal (PC) combustion is the most widely used technology for utilityscale power generation in the world. In PC boilers, coal is ground into fine particles (∼100 μm) and then injected with heated combustion air through a number of burners into the lower part of the furnace.
