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.Get a Quote

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 ...Get a Quote
The Effect of Moisture on Heating Valu
The heating value of any fuel is the energy released per unit mass or per unit volume of the fuel when the fuel is completely burned (ANSI/ASABE S593.1 2011). The term calorific value is synonymous to the heating value. Typical units for expressing calorific or heating value are MJ/kg in …Get a Quote

Calorific Value - an overview | ScienceDirect Topi
Calorific value or heat of combustion of a fuel is the amount of heat developed by a fuel when completely burned. Gross calorific value of fuel oils varies within a comparatively narrow range, highest value of 48 MJ/kg is for light distillate to the lowest value of 42 MJ/kg for heavy fuel oil.Get a Quote
Boiler Efficiency and Combustion | Spirax Sar
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.Get a Quote
