  • In a given combustion process, that takes place adiabatically and with no work or changes in kinetic or potential energy involved, the temperature of the products is referred to as the ‘adiabatic flame temperature’.

  • With the assumptions of no work and no changes in kinetic or potential energy, this is the maximum temperature that can be achieved for the given reactants because any heat transfer from the reacting substances and any incomplete combustion would tend to lower the temperature of the products.

  • The maximum temperature achieved through adiabatic complete combustion varies with the type of reaction and per cent of theoretical air supplied.

  • An increase in the air-fuel ratio will effect a decrease in the maximum temperature.

  • The adiabatic flame temperature can be controlled by the amount of excess air that is used.
