  • Pulverized Coal Boiler

    A typical pulverized coal boiler consists of (1) the furnace, which is the lower boiler part, where the burners and the firing system are installed and where the combustion takes place and (2) the convective section, where the convective heat exchanger surfaces are installed. The boiler membrane walls have usually the function of the boiler evaporator.

    Jan 01, 1982 · Jan 01, 1982 · Pulverizedcoal firing. The essential feature of pulverizedcoal firing is that throughout the combustion the fuel is suspended as a cloud of small particles in the combustion air. Because they follow more or less the same path as the combustion air, fuelparticle residence times are short compared with those in fixedbed appliances.
