This patent describes an apparatus for cooling high temperature waste gas comprising: a vertically extending trough-shaped housing having downwardly and inwardly tapering ends walls and side walls at the lower portion thereof terminating at a closed bottom, to form a cylindrically-shaped housing; a bed of solid particulate material disposed in the trough-shaped housing having an upper surface spaced from the closed bottom; at least one gas injection nozzle communicating with the housing at the closed bottom; means for injecting high temperature waste gases upwardly through the gas injection nozzle into the bed of solid particulate material to fluidize the bed, such that the jet of hot waste gas is dissipated in the fluidized bed without substantially disturbing the surface thereof, and the gas is cooled by contact with the solids; means for discharging cooled waste gases from the housing after passage through the bed of solid particulate material; means for charging cooled solid particulate material into the housing in the bed, at a location spaced from the bottom wall for passage downwardly therethrough; means for discharging heated solid particulate material from the bottom wall of the housing; means for cooling the heated solid particulate material outside the housing; and means for returning the cooled particulate material to the means for charging.
