  • 11.10 Coal Cleaning

    Fine coal processing and coarse coal processing use similar operations and equipment to separate the contaminants. The primary difference is the severity of operating parameters. The majority of coal cleaning processes use upward currents or pulses of a fluid such as water to fluidize a bed of crushed coal and impurities.

  • Mass balance technique applied to unit operation of coal

    Dec 31, 1996Abstract. In a coal preparation plant, it is a common practice to analyze the coal samples both in terms of relative density and size distributions from the process streams for the process evaluation. However, the plant measured data obtained from feed and product streams around the unit operations are subjected to measurement errors.
