Flame Temperatures some Common Gases

Adiabatic flame temperatures for some common fuel gases - propane, butane, acetylene and more - air or oxygen atmosphere

The flame temperatures for some common fuel gases can be found in the table below:

Fuel Gas Combustion with Oxygen
(oC)
Combustion with Air
(oC)
Acetylene 3,100 2,400
Butane 1,970
Carbon Monoxide 2,121
Ethane 1,960
Hydrogen 2,660 2,045
MAPP1) 2,980  
Methane 2,810 1,957
Natural Gas 2,770  
Propane 2,820 1,980
Propane Butane Mix   1,970
Propylene 2,870  

Note! Initial gas, air and oxygen temperature at 20oC. No excess air/oxygen.

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