WebGross & Net Calorific Values Gross CVor ‘higher heating value’ (HHV) is the CV under laboratory conditions. Net CVor ‘lower heating value’ (LHV) is the useful calorific value in boiler plant. The difference is essentially the latent heat of the water vapour produced. Conversions – Units From kcal/kg to MJ/kg multiply kcal/kg by 0.004187 WebEnvironmental emission of carbon dioxide CO 2 when combustion fuels like coal, oil, natural gas, LPG and bio energy. To calculate the Carbon Dioxide - CO 2 - emission from a fuel, the carbon content of the fuel must be multiplied with the ratio of molecular weight of CO 2 (44) to the molecular weight of Carbon (12) -> 44 / 12 = 3.7.

For example: Unit Gross Load = 600,000. Unit Coal Flow = 620,000 Lbs/he. Burn Rate = 620/600 = 1.033. If the Gross Heat Rate is 10,000 Btu/KW. Then the Btu/lb of the coal would be. Btu/lb = 10,000/1.033 = 9,680 Btu/lb nadeerah coles new castle de
