Fuels Higher and Lower Calorific Values
Energy content or calorific value is the same as the heat of combustion, and can be calculated from thermodynamical values, or measured in a suitable apparatus:. A known amount of the fuel is burned at constant pressure and under standard conditions (0#176;C and 1 bar) and the heat released is captured in a known mass of water in a calorimeter. If the initial and final temperatures of the water
