ABSTRACT:
Stirrer construction adapted for both vertical and rotational movements is described for use in a fixed bed coal gasifier. Rabble arms projecting from a depending shaft are arranged as an upper and a lower set. The rabble arms in the lower set each present shear edges at and adjacent the tips thereof in order to be lowered into the ash zone, when desired, to break away the hard sintered masses that tend to develop along the wall there. Also, the lower set of rabble arms is designed for use in the combustion ("hot") zone to break up or loosen clinker formation with minimum damage to the ceramic liner in this portion of the gasifier. The rabble arms in the upper set are longer than the rabble arms in the lower set and extend closer to the wall of the gasifier being used both in order to center the stirrer shaft and to stir the upper regions of the coal bed.
