Adiabatic Flame Temperature
When a combustion reaction takes
place energy is released to the combustion products. If no heat is lost in
this process, the temperature of the combustion products is known as the "Adiabatic
Flame Temperature."
For methane combustion in air at 1 atmosphere
the Adiabatic Flame Temperature is
2,328 K or 2055 C. For hydrogen
burning in air at 1 atmosphere the Adiabatic Flame temperature is 2,400 K or
2127 C.
When a flame loses heat to the environment, or is diluted with
an inert material that has to be heated with the heat released in the combustion
reaction, the actual temperature reached is less than the ideal adiabatic
flame temperature. This is the actual "Flame Temperature."
Remember
that a measuring device (thermocouple) may also remove heat from the flame.
How? What effect does this have on your data? |
