Fuel and oxidizer enter the reaction chamber through separate ports. However, the products leave through a single exit.

Set up the reaction as fuel+oxidizer-->products. In the state panel, evaluate the states of fuel, oxidizer and products. The combustion device (device panel) has two inlets, i1 and i2, one for fuel and one for oxidizer, and one exit (e) for the products. Use this daemon not only for energy or entropy analysis of a combustor, but also for balancing a combustion reaction (for given products analysis, excess or deficient air, fuel analysis, etc.).

Fuel and Oxidizer (reactants) are premixed and enters the combustion chamber through a single inlet. Also, the products leave through a single exit.

Set up the reaction as reactants-->products. You may have to manually balance the reaction. The products composition is frozen (dictated by the reaction you set up) during the process analysis. In the state panel, evaluate the states of reactants and products. The combustion process executed by the mixture takes it from a unique b (begin) state to a single f (final) state.
