higher heating value of crushed coal

  • Calorific Value

    Calorific Value

    Heating value of coal can be determined either of the two specified methods – ASTM D3286 or D2015. ASTM D3286 specifies heating value determination by isothermal Jacketted Bomb Calorimeter (whose accuracy depends on the operator) and ASTM D2015 specifies determination of the same by Adiabatic Bomb Calorimeter, which is automated and most widely used.
