  • Soot blower system
    Patent number: 4488516
    Abstract: A soot blower system comprising a plurality of soot blowers (60) each of which is selectively operable to clean ash deposits (54) from the walls (12) of a furnace chamber (10) in direct response to the local heat transfer rate from the hot combustion products to the walls of the furnace sensed by one or more heat flux meters (62) mounted to the furnace wall in the general region surrounding each of the soot blowers.

  • Fluidized bed fuel feed system
    Patent number: 4446799
    Abstract: At least one movable nozzle (14) is mounted in an opening (18) in the wall of a fluidized bed reactor (22). Solid feed materials (62) in granular form are conveyed to the nozzle (14) and injected into the reactor (22). By changing the direction of the solids injection flow stream, the mixing, residence, and reaction characteristics of the reactor (22) may be controlled. The nozzle (14) is elongated and arranged so as to tilt on a horizontal axis (58), and may inject fresh material or recycled material previously removed from the bed reaction zone (34).
