Adiabatic Flame Temperatures

Adiabatic flame temperature hydrogen, methane, propane and octane - in Kelvin

A combustion process without heat loss or gain is called adiabatic.

Adiabatic flame temperatures for hydrogen, methane, propane and octane - and others - with oxygen or air as oxidizers in a constant pressure adiabatic reaction:

4) Other hydrocarbons

  • reactants enter the combustion process at 25oC (77oF) and 1 atm pressure
  • products leaves the process at 1 atm pressure
  • combustion is stoichiometric without any excess air

Excess air will reduce the adiabatic flame temperature and is often introduced to avoid flame temperatures exceeding limits sets by the materials in the combustion system.

Methane is the major part in Natural gas.
