 1967.    KOREVAAR, A.  [Influence of Water Vapor in Gas Generators.]  Chem. Weekblad, vol. 22, 1925, pp. 66-73; Chem. Abs., vol. 19, 1925, p. 1622.

        Earlier work is critically reviewed.  It is concluded that the water-gas equilibrium H₂O+CO=CO₂+H₂ plays a very unimportant role; it is virtually never reached.  The reactions taking place are solely determined by the equilibrium conditions for (I)C+H₂O=CO+H₂ (Lang) and (II) 2CO=C+CO₂ (Boudouard).  it is not yet possible to give a complete calculation of the reactions involved.  From a technical point of view, Bone and Wheeler’s result that only a limited amount of H₂O can be completely utilized, is very important.  A partial calculation shows that at a lower temperature of the combustion zone more H₂O vapor can be decomposed.
