Pulverised Coal Combustion - an overview | ScienceDirect ...

Pulverised coal (PC) combustion is the most widely used technology for utility-scale 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. Particles burn in suspension and release heat which is transferred into the steam cycle.

Coal Pulverizer - Pall

Mechanically pulverizing coal into a fine powder enables it to be burned like a gas, thus allowing more efficient combustion.
