Abstract:

A heat recovery process for use in gasification of solid carbonaceous fuel such as coal utilizing a fluidized bed of char. The vapor and entrained char dusts rise from a gasification section into a gas solids disengaging section and into a heat recovery section, from which a major portion of the char solids are returned to the gasification section. The vapor and some retaining fine solids pass upwardly into the cooling section containing a fluidized bed of char particles maintained at a temperature of about 800. degree. -1500. degree. F. by a cooling fluid to solidify sticky ash on the char particles. The char containing the sticky ash is then returned to the lower gasification section for reheating and further gasification reactions. The remaining fine solids are separated from vapors and returned to the lower fluidized beds, and a clean product gas stream is withdrawn.

Abstract:

An inlet guide vane assembly for a compressor is provided. The inlet guide vane assembly may include a hub configured to be disposed in an inlet of the compressor, and an inlet guide vane extending from the hub. The inlet guide vane may include a stationary section configured to be coupled with the inlet and a mobile section disposed adjacent the stationary section. The mobile section may include a rod configured to extend through an opening formed in the inlet. The inlet guide vane assembly may also include at least one biasing member disposed about the rod and configured to exert a biasing force on the mobile section to urge the mobile section radially outward.
