Common Flame Temperatures
Assuming initial atmospheric conditions (1 bar and 20 °C), the following table list the adiabatic flame temperature for various gases under constant pressure conditions. The temperatures mentioned here are for a stoichiometric fuel-oxidizer mixture (i.e. equivalence ratio ).
Note these are theoretical, not actual, flame temperatures produced by a flame that loses no heat. The closest will be the hottest part of a flame, where the combustion reaction is most efficient. This also assumes complete combustion (e.g. perfectly balanced, non-smokey, usually bluish flame)

Famous quotes containing the words common and/or flame:
“We must return optimism to our parenting. To focus on the joys, not the hassles; the love, not the disappointments; the common sense, not the complexities.”
—Fred G. Gosman (20th century)
“Fan the sinking flame of hilarity with the wing of friendship; and pass the rosy wine.”
