calculation of hot air required for a coal mill

  • Coal GrindingCement Plant Optimization

    Coal Moisture The degree of drying and therefore the required mill outlet temperature (from 65-80 0 C) will depend upon the type of coal ground. Some residual moisture in fine coal is recommended (Graph below) to minimize the potential of spontaneous ignition of fine coal which will again vary for different coal types as below

  • Stoichiometric Air or Theoretical Air Quantity

    The theoretical air required to burn the coal is = 1.64 / 23.2 = 7.1 kg of Air for 1 kg of Coal. This is the theoretical air required to burn the coal. Quick Calculation. The heating value of coal also depends on the elemental carbon and hydrogen. This means that the air required and the heating value have an almost fixed relationship.
