606.    ---------------.  [COKE AND SMOKELESS-FREE AGE.]  Winkler Gasification Process.  Vol. 8, 1946, pp. 155-158.

     Winkler continuous gasification process, which uses a steam and O₂ mixture as the blast, is described, and its performance in various German plants is discussed.  The great economic advantage of the process is its ability to gasify low-grade, cheap fuels.  In  fact this is its only compensatory feature for its relatively poor thermal efficiency and the inconvenience and cost of using O₂.  The capital cost of a Winkler plant is about the same as that of a complete water-gas plant of normal type.
