Theoretical adiabatic flame temperature
WebbThe maximum temperature of the flame slightly exceeds the theoretical adiabatic value owing to the thermal feedback. The temperature of the burned gases decreases almost linearly to slightly below the theoretical adiabatic value at the exit from the combustion chamber, thereby providing a nearly isothermal post-flame zone. The rate of formation Webbof propane (C3H8) and air such that the equivalence ratio was equal to 0.65, with a theoretical adiabatic flame temperature of 1800 K. The …
