The calorific values of a fuel, whether it bituminous coal, smokeless fuel or logs, will tell you how well the fuel burns, the level of heat energy emitted and any waste products produced during the burning process. This data can be used for several purposes such as comparing the quality of fuels and to identify whether a smokeless fuel is actually a “smokeless fuel”.

16/09/2011· The stored energy potential within coal is described as the “calorific value,” “heating value,” or “heat content.” It's measured in British thermal units (Btu) or millijoules per kilogram (MJ/kg). A Btu is the amount of heat that will warm approximately 0.12 U.S. gallons—a pound of water—by 1 degree Fahrenheit at sea level. MJ/kg represents the amount of energy stored in

The calorific value of a fuel is the quantity of heat produced by its combustion – at constant pressure and under “normal” (standard) conditions (i.e. to 0 o C and under a pressure of 1,013 mbar). The combustion process generates water vapor and certain techniques may be used to recover the quantity of heat contained in this water vapor by condensing it.

Heat Values of Various Fuels. The heat value of a fuel is the amount of heat released during its combustion. Also referred to as energy or calorific value, heat value is a measure of a fuel's energy density, and is expressed in energy (joules) per specified amount (e.g. kilograms).
