CLARIFYING THE USES OF HEATING VALUES

WebCalorific value (also called heat value or heating value) is the total heat released from a complete combustion of coal [105]. It is an important indicator for coal combustion efficiency and used to control the combustion temperature of coal utilization devices. Moreover, heat value is used to determine coal ranks and prices. The higher heating value is experimentally determined in a bomb calorimeter. The combustion of a stoichiometric mixture of fuel and oxidizer (e.g. two moles of hydrogen and one mole of oxygen) in a steel container at 25 °C (77 °F) is initiated by an ignition device and the reactions allowed to complete. When hydrogen and oxygen react during combustion, water vapor is produced. The vessel and its contents are then cooled to the original 25 °C and the higher heating value is det… WebA British thermal unit (Btu) is a measure of the heat content of fuels or energy sources.
