  • Boiler - Efficiency

    The energy provided by a fuel may be expressed in two ways - 'Gross' or 'Net' Calorific Value. 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.Get Price
