Coal Quantity. Since coal has a heat value of 20,000 kJ/kg, for producing one kw.hr we require (10765 / 20000) 0.538 kg of coal. This translates to (0.538 x 100 x 1,000) 53800 kg/hr (53.8 T/hr) of coal for an output of 100 MW. Coal Cost. Basic cost of coal depends on the market conditions.

Bituminous coal, for example, has a higher calorific value than sub-bituminous or lignite coal. It can range from about 24 to 35 megajoules per kilogram (MJ/kg). Natural Gas: Natural gas has a calorific value that can vary, but it is typically around 45 to 55 megajoules per cubic meter (MJ/m³) or 1,000 to 1,200 BTU per cubic foot.

If the Coal sampled at the mines has an HHV of 18800 kJ/kg the same coal at the boiler will have a higher HHV. This is because the percentage of combustibles in one kg is more. Based on a simple proportion calculation, multiplying by a factor [100-8]/ [100-20] the HHV will be 21620 kJ/kg. In real life, Coal analysis takes place in the laboratory.

Explanation: For calculating the GCV of the coal use the formula GCV=w (T2-T1)/V, where w=weight of water and v=volume of fuel burnt. Substitute the corresponding values and we know that NCV is given by NCV=GCV – [(M/V)587], M is the weight of the water obtained by steam.

Definition and Calculation. Gross Calorific Value (GCV) and Net Calorific Value (NCV) are both measures of the heating value of a fuel. GCV represents the total amount of heat released when a fuel is burned completely, while NCV takes into account the heat lost in the process of combustion.
