    11 Bituminous And Subbituminous Coal Combustion

    The most common heat transfer method for coal-fired boilers is the watertube method in which the hot combustion gases contact the outside of the heat transfer tubes, while the boiler water and steam are contained within the tubes. Coal-fired watertube boilers include pulverized coal, cyclone, stoker, fluidized bed, and handfed units.
