An apparatus for the combustion of a combustible material present on fluidized solid particles which apparatus is described comprises: (a) a vertically oriented combustion chamber having a cylindrical vertical sidewall, with an opening being located in the sidewall; (b) a disengagement chamber located superadjacent to the combustion chamber and in communication therewith, there being a hot fluid particle collection section located at the bottom of the disengagement chamber; (c) a cooling chamber surrounding at least one heat exchanger; (d) a hot particle conduit of vertical orientation connecting the hot particle collection section of the disengagement chamber with the cooling chamber particle inlet opening such that hot particles can flow downwardly from the disengagement chamber to the cooling chamber; (e) a particle flow restriction means in the hot particle conduit; (f) an open passageway connecting the particle outlet opening of the cooling chamber with the opening located in the sidewall of the combustion chamber and providing means for the flow of cooled particles and fluidizing gas from the heat exchanger to the combustion chamber; (g) a fluidizing gas inlet conduit connected to a bottom portion of the cooling chamber providing means for the passage of fluidizing gas onto the shell side of the heat exchanger and maintaining a fluidized catalyst bed within the cooling chamber; and, (h) a means to control the flow of fluidizing gas in the fluidizing gas inlet conduit.
