1.1 Bituminous And Subbituminous Coal Combustion
In pulverized coal-fired (PC-fired) boilers the fuel is pulverized to the consistency of talcum powder (i.e. at least 70 percent of the particles will pass through a 200-mesh sieve) and pneumatically injected through the burners into the furnace. Combustion in PC-fired units takes place almost entirely while the coal is
