Circulating fluidized beds are capable of burning a wide range of low-quality and low-cost fuels. The largest operating CFB today is 340 Megawatts MW although units up to 600 MW are being proposed as commercial offers. Pulverized coal-fired boilers are available in capacities over 1000 MW and typically require better quality fuels. Advanced Pulverized Coal Combustion PC Technology Pulverized Coal Process Description In a pulverized coal-fueled boiler coal is dried and ground in grinding mills to face-powder fineness less than 50 microns . It is transported pneumatically by air and injected through burners fuel-air mixing devices into the combustor. Coal particles burn in suspension and release heat which is transferred to water tubes in
