Calorific Value or Heating Value of the Fuel & Moisture .

The Heating Value determines how much fuel is required in the power plant. Higher the Calorific Value lesser the amount of the coal required per unit of Electricity. Higher Calorific value also means the cost of the coal is higher but is offset by the lower cost of logistics, storage and ash disposal.

Gross Calorific Value. This is the theoretical total of the energy in the fuel. The gross calorific value of the fuel includes the energy used for evaporating the water in the combustion process. The flue gases from boilers are in general not condensed. The actual amount of heat available to the boiler plant is therefore reduced. Gross ...

Net calorific value. This is the calorific value of the fuel, excluding the energy in the steam discharged to the stack,and is the figure generally used to calculate boiler efficiencies. In broad terms: Accurate control of the amount of air is essential to boiler efficiency: Too much air will cool the furnace, and carry away useful heat.

The calorific value of a fuel is amount of heat liberated by its complete combustion. For solid and liquid fuels, calorific value is expressed in kJ/kg, whereas for gaseous fuels it is expressed as kJ/m 3 where m 3 is normal cubic metre measured at NTP conditions i.e., at 0°C temperature and 760 mm Hg barometric pressure (1.01325 bar).
