ABSTRACT:
A solid fuel gasifying unit is used to convert coal and other combustible organic solids to gaseous end products. Solid feed enters the vertical preheat zone of S-shaped gasifying unit and is mixed with a hot recycle reagent such as clay. The solid material fills the preheating zone of the unit to an elevation sufficient to create a gravitational particle flow which forces the solid particles in the lower end of the zone into the bottom of a vertical gasifying zone and through the remaining sections of the unit. In the gasifying zone, a fluidizing gaseous stream such as carbon dioxide or steam is injected to enhance the flow of the solid particles.
Also disclosed is a gas fractionating unit and a relatively high pressure solid fuel gasifying unit which contain a reagent powder having a significant weight difference in reduced form as compared with the weight of the powder in oxidized form and which may be circulated through the unit under gravity flow during oxidation-reduction chemical processing. The gas fractionating unit may be used in combination with either gasifying unit, and each unit provides an efficient means to circulate solid particles.
