                   In actual operation of a water-gas generator, equilibrium is not attained, but is approached to an extent depending on the reactivity of the coke, the contact time, etc.  The thermal yield, P, is defined as the ratio of the heat of combustion of the gas produced to that of the gas resulting from complete reduction of CO₂ and H₂O to CO and H₂.  P is empirically determined to be a function of the volume content and degree of reduction of the CO₂ and H₂O separately, in the inlet gas.  Values of this function are tabulated and plotted.
