Gross calorific value. This is the theoretical total of the energy in the fuel. However, all common fuels contain hydrogen, which burns with oxygen to form water, which passes up the stack as steam. The gross calorific value of the fuel includes the energy used in evaporating this water. Flue gases on steam boiler plant are not condensed, therefore the actual amount of heat available to the boiler plant …

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

Dec 30, 2018 · So the quality of the fuel used in a thermal power generating plants plays a vital role in that sense. The calorific value of a fuel determines the quality of the fuel. We define the calorific value of a fuel as the amount of heat produced by complete combustion of one unit of the fuel.

Solution: One kg of carbon burning to CO2 liberates 35000 kJ, and one kg of hydrogen liberates 143000 kj, when the products of combustion are cooled down to 25°C. Higher calorific value = 0.85 × 35000 + 0.125 × 143000. = 47750 kJ/kg. Lower calorific value = 47750 – 9 × 0.125 × 2442. = 45000 kJ/kg.

Boiler Fuels [] Introduction []. All boiler systems employ a fuel mechanism which basically comprises of the apparatus needed to supply fuel for heat generation. The design of the apparatus in use varies according to the kind of fuel employed in the system. Variety of fuels is available for application in boilers, each having different chemical properties.

There are several measures by which the boiler efficiency of a heating plant can be improved such as the installation of condensing boilers, the periodic tune-up of the boilers, and control operations especially for modular boilers. The net effect of any energy efficiency measure is some savings in the fuel use by the heating plant.
