      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.

      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.

      Global Clean Coal Technology Market Share by Type

      Since coal is rich in carbon, its combustion leads to the production of energy. Coal is primarily used for electricity and power generation and is categorized into four different types depending on the carbon, oxygen, and hydrogen content present in it. The higher the carbon content, the greater the energy contained by the coal.
