Fuel and air are fed to an adiabatic furnace, and the fuel undergoes complete combustion to form CO₂ and H₂O. One of five hydrocarbons can be selected as the fuel. The energy released by combustion raises the temperature of the exhaust gases. The adiabatic flame temperature (the exhaust gas temperature) is calculated using an energy balance. Press details for more information. The feed temperatures of fuel and air and the percent excess air are selected with sliders. The calculated flame temperatures in this simulation may be up to 110 K higher than tabulated adiabatic flame temperature values for a stoichiometric feed (or less when excess air is fed) because endothermic dissociation reactions to form H₂, O₂, and CO were not included.
