Markus Hurskainen, Pasi Vainikka, in Fuel Flexible Energy Generation, 2016. 7.2.3.1 General. 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.
