The adiabatic flame temperature is the temperature that would be achieved by a flame if the process of combustion took place in the absence of heat loss to the surroundings. In meteorology and oceanography , the adiabatic cooling process produces condensation of moisture or salinity and the parcel becomes oversaturated.
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 ...
Similarly the temperature which would be achieved by a flame in the absence of heat loss to the surroundings is called as adiabatic flame temperature. An adiabatic process can be reversible and known as an isentropic process. The irreversible adiabatic process which extracts no work is called as an isenthalpic process.
Adiabatic Process An adiabatic process is one in which no heat is gained or lost by the system. The first law of thermodynamics with Q=0 shows that all the change in internal energy is in the form of work done. This puts a constraint on the heat engine process leading to the adiabatic condition shown below. This condition can be used to derive the expression for the work done during an ...
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.
The formula for the rise in temperature of air, when it is compressed so rapidly that there is not time for any significant amount of heat to be lost is: k This is called an adiabatic compression. In practice you could never compress the air fast enough to keep from some heat being lost but this calculation sets an upper limit.

5.4 Adiabatic flame temperature calculation The temperature of the products in an adiabatic combustion of fuel without applying any shaft work, is defined as the “Adiabatic Flame Temperature”.
formula where the square root is added is feasible and the value where the square root is subtracted is not, this value can be discarded and assumed to be the value obtained when . Pupo: Adiabatic Flame Temperature for Combustion of Methane Produced by The Berkeley Electronic Press, 2011
As was explained at the top of this page, the easiest path is to react the materials at the inlet temperature and then heat everything in the outlet stream up to the final temperature. Thus, we write, Since adiabatic, where Q has been set to zero since we are finding the maximum or adiabatic flame temperature.
