A combustion process without heat loss or gain is called adiabatic.. Adiabatic flame temperatures for some common fuel gases like hydrogen, methane, propane and octane - with oxygen or air as oxidizers in a constant pressure adiabatic reaction - are indicated below:


In daily life, the vast majority of flames one encounters are those caused by rapid oxidation of hydrocarbons in materials such as wood, wax, fat, plastics, propane, and gasoline.The constant-pressure adiabatic flame temperature of such substances in air is in a relatively narrow range around 1950 °C.


This is a list of flame temperatures for various common fuels. Adiabatic flame temperatures for common gases are provided for air and oxygen. For these values, the initial temperature of air, gas, and oxygen are 20 °C. MAPP is a mixture of gases, chiefly methyl acetylene, and propadiene with other hydrocarbons.


Consider for example the case of finding the temperature of the hottest part of a propane flame. If we try to find the maximum possible temperature of that flame due to combustion of propane in air, we would want to assume adiabatic conditions. This seems rather strange, because we have all stood around a fire and felt the heat given off.

15. 5 Adiabatic Flame Temperature For a combustion process that takes place adiabatically with no shaft work, the temperature of the products is referred to as the adiabatic flame temperature. This is the maximum temperature that can be achieved for given reactants. Heat transfer, incomplete combustion, and dissociation all result in lower ...


The adiabatic flame temperature is a measure of the maximum temperature that could be reached by combusting a particular gas mixture under a specific set of conditions. In a real system which includes heat losses, chemical kinetic and/or mass transport limitations, the flame temperature is likely to be lower than the adiabatic flame temperature.


Adiabatic Flame Temperature - The opposite extreme of the above example in which we evaluated the enthalpy of combustion is the case of an adiabatic process in which no heat is released. This results in a significant temperature increase in the products of combustion (denoted the Adiabatic Flame Temperature ) which can only be reduced by an ...
