Various Grades Of Coal

  • Experience with Various Coals in Power Plants in the

    Coal-based power plants in the United States and Europe use various coal grades which extend from lignites and sub-bituminous coals to a wide range of bituminous coals and anthracites. Appropriate characterization of coal is important for the design of the steam generators, their associated firing systems and assessment of the operating results. This paper presents examples of the design of
