This is a list of flame temperatures for various common fuels. Adiabatic flame temperatures for common gases are provided for air and oxygen. (For these values, the initial temperature of air, gas, and oxygen is 20 °C.) MAPP is a mixture of gases, chiefly methyl acetylene, and propadiene with other hydrocarbons. You'll get the most bang for your buck, relatively speaking, from acetylene in oxygen (3100°C) and either acetylene (2400°C), hydrogen (2045°C), or propane (1980°C) in the air.

Flame Temperatures

This table lists flame temperature alphabetically according to the name of the fuel. Celsius and Fahrenheit values are cited, as available.
