This patent describes a process of producing a gas substantially composed of water gas and distillation gas from bituminous fuel. The process consists of establishing and maintaining a bed of incandescent coke in a gas-generating chamber and a superimposed mass of bituminous fuel to be distilled upon the same in immediate contact therewith in a distillation chamber. The order of operation includes: (a) blowing air through the incandescent coke to form producer or blast gas burning at least a part of the said producer gas in flues surrounding the said distillation chamber, (b) passing steam through the said flues and thereby superheating the steam and introducing it at about the junction point of the distillation chamber and the gas-generating chamber, and (c)passing a part of this steam through the mass of the fuel in the distillation chamber and simultaneously passing the other part of this steam downwardly through the incandescent coke in the gas-generating chamber. Steps (a) and (b) are alternately repeated, while drawing off the resulting mixture of water gas and distillation gas from the distillation chamber. The water gas formed is drawn off in the gas-generating chamber and said fuel is replenished to maintain both the fuel and the incandescent coke.
