ABSTRACT:
A method and apparatus for cooling waste gases of a temperature in excess of 800.degree. C. using radiant heat transfer to a plurality of fluidized beds. Solid particulate material is contained within a housing and divided into a plurality of fluidized beds by baffle means and fluidizing gas injected upwardly through the solids, without transfer of solids from the upper surface of a bed to adjacent beds. The hot waste gas is cooled by radiant heat transfer through the surfaces of the beds. Heated solids are cooled by either flow through the housing and cooling of the same outside the housing, or by coolant passed through heat transfer tubes that are positioned within the beds of solid particulate material.
