HEATING VALUE Meaning and
Definition
-
Heating value, also known as the heat of combustion or energy content, refers to the amount of heat energy released when a given substance undergoes complete combustion. It is a quantitative measure of the heating potential of a fuel or a combustible material. Heating value is typically expressed in terms of the energy released per unit mass or unit volume of a substance.
The heating value of a substance is determined by the chemical composition of the material and represents the total energy content stored within its molecular structure. It is influenced by factors such as the amount of carbon, hydrogen, and other combustible elements present in the substance.
When a fuel is burned or oxidized, the chemical bonds between atoms are broken and reformed, releasing heat energy as a result. This released energy represents the heating value of the fuel. It is commonly measured in either British thermal units (BTU) or joules per unit mass of the substance.
The heating value is a crucial parameter in various applications, particularly in the energy and fuel industries. It is used to evaluate and compare the energy efficiency of different fuels, determine the amount of energy available for heating or power generation, and assess the environmental impact of combustion processes. By understanding the heating value of a fuel, manufacturers, engineers, and consumers can make informed decisions regarding its utilization, taking into account factors such as cost, energy efficiency, and sustainability.

Etymology of HEATING VALUE
The word "heating" originated from the Middle English term "heten" which means "to make hot". It can be traced back to the Old English word "hǣtan". "Value" comes from the Latin term "valere" which means "to be worth". So, "heating value" refers to the worth or importance of the heat produced by a particular substance.
