Table 1: Flame Temperatures of Common Gases and Fuels
| Gas / Fuels | Flame temperature |
|---|---|
| Propane in air | 1980 °C |
| Butane in air | 1970 °C |
| Wood in air (normally not reached in a wood stove) | 1980 °C |
| Acetylene in air | 2550 °C |
| Methane (natural gas) in air | 1950 °C |
| Hydrogen in air | 2111 °C |
| Propane with oxygen | 2800 °C |
| Acetylene in oxygen | 3100 °C + |
| Propane-butane mix with air | 1970 °C ~ |
| Coal in air | 1900 °C (blast furnace) |
| Cyanogen (C2N2) in oxygen | 4525 °C |
| Dicyanoacetylene (C4N2) in oxygen | 4982 °C (highest flame temperature) |
Info & Assuming:
- Adiabatic flame
- 20 degrees Celsius 1 bar atmosphere
- Complete combustion (no soot and more blue-like flame is the key) (Stoichiometric)
- Peak Temperature
- Speed of Combustion (has no effect on temp, but more energy released per second (as adiabatic) compared to normal flame)
- Spectral bands also affect colour of flame as of what part and elements of combustion
- Blackbody radiation (colour appearance only because of heat)
- Atmosphere - affects temperature of flame and colour due the atmospheric colour effect

Famous quotes containing the words table, flame, common and/or gases:
“The salt person and blasted place
I furnish with the meat of a fable;
If the dead starve, their stomachs turn to tumble
An upright man in the antipodes
Or spray-based and rock-chested sea:
Over the past table I repeat this present grace.”
—Dylan Thomas (1914–1953)
“And all shall be well and
All manner of thing shall be well
When the tongues of flame are in-folded
Into the crowned knot of fire
And the fire and the rose are one.”
—T.S. (Thomas Stearns)
“When a man says that he is Jesus or Napoleon, or that the Martians are after him, or claims something else that seems outrageous to common sense, he is labeled psychotic and locked up in a madhouse. Freedom of speech is only for normal people.”
—Thomas Szasz (b. 1920)
“The bird is not in its ounces and inches, but in its relations to Nature; and the skin or skeleton you show me, is no more a heron, than a heap of ashes or a bottle of gases into which his body has been reduced, is Dante or Washington.”
—Ralph Waldo Emerson (1803–1882)
