Wet way combustion and water vapor pump-cycle

Wet combustion often gives rise to multiple phase changes of water, particularly when this water is introduced in the liquid phase or when latent heat recovery is targeted.

Based on the first principle of thermodynamics, we can show that the sum of the heat and work produced by combustion in a thermal machine with combustion was equal to the difference between the enthalpies entering the machine and those rejected with the fumes (
