Adiabatic flame temperature

The adiabatic combustion temperature is a characteristic of engineering science and combustion theory. It characterizes a combination of fuel and oxidizer, the condition is known before the start of combustion.

The adiabatic combustion temperature is the temperature that results after the completion of combustion, when the gas mixture has no heat exchanged with the environment during combustion (hence adiabatic).

Since a flame i.d.R. hotter than their surroundings, lose flames during the combustion heat. Therefore, the actual flame temperature below the adiabatic combustion temperature. The temperature of a flame can only be above the adiabatic combustion temperature are in reverse, if the environment is hotter than the flame.

The following variables have an influence on the adiabatic combustion temperature:

• The calorific value of the fuel. (It is used instead of the calorific value of the calorific value, since it is assumed that water is present after the combustion gas)
• The chemical composition of the fuel
• The composition of the oxidizer. ( such as air )
• The initial temperatures of the fuel and oxidizer
• The air ratio
