    1.1 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.

    We also present recommendations for reliable burning of various sub-bituminous coals and their blends in a 575 MW tangentially-fired boiler. For example, we found that firing Indonesian sub-bituminous coals (Adaro and Melawan) considerably reduced NO x (30% reduction) and SO x (reduced to 200 mg/dNm 3 @6%O 2) emissions without post combustion

    Bituminous Coal | Hand Fired Boilers & Furnaces Using

    Oct 23, 2007 · If the Firebox is designed to burn high volitile bituminous coal it will have a provision for pre-heated air entering over the top of the fire to add extra oxygen to the smoke, which burns off a lot of it. But the provision of over the fire pre-heated air is not a common feature in stoves claiming to burn Bituminous coal. It actually is quite rare.

    Boiler Fuels, Emissions and Efficiency - CED Engineering

    Bituminous coals are used routinely by electric utilities and in some industrial applications to fire steam-generating boilers even though their sulfur content can be relatively high. Compared to lignitic and subbituminous coals, the heating value of bituminous coals range between 10,500 and 14,000 Btu/lb.

    Boiler Efficiency - an overview | ScienceDirect Topics

    The boiler efficiency of modern pulverized fuel, hard coal-fired units is 94%–95% (LHV basis), reducing slightly to 90%–91% for lignite-fired units due to the higher moisture content. When combined with the other elements of the Rankine cycle, the overall efficiency currently achievable in conventional plants is in the 40%–45% range.
