Fuel Gases - Flame Temperatures

Adiabatic flame temperatures for common fuel gases - propane, butane, acetylene and more - in air or oxygen atmospheres.

Flame temperatures for some commonly used fuel gases:

Fuel Gases - Flame Temperatures
GasCombustion with Oxygen
(oC)
Combustion with Air
(oC)
Acetylene 3480 2500
Butane 1970
Carbon Monoxide 2121
Ethane 1955
Hydrogen 3200 2210
MAPP1) 2927 2010
Methane 1950
Natural Gas 1960
Propane 2526 1967
Propane Butane Mix   1970

Note! Initial gas, air and oxygen temperature at 20 oC. Stoichiometric Combustion - no excess air/oxygen.

1) MAPP gas is a mixture of various hydrocarbons, principally, methyl acetylene and propadiene.
