Flame Temperatures

Typical Flame Temperature for Different Fuels


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 are 20 °C. MAPP is a mixture of gases, chiefly methyl acetylene and propadiene with other hydrocarbons.
