Hedrick, B W

An apparatus is described for the combustion of carbonaceous materials present on fluidizable particles employed in a hydrocarbon conversion process which comprises: (a) means for confining a fluidized mass of the particles comprising a chamber, a particle inlet, a particle outlet, an oxygen-containing gas inlet and a flue gas outlet, with the flue gas outlet communicating with an upper end of the chamber; (b) a steam generating chamber having associated therewith a means to charge liquid water to the steam generation chamber and remove steam from an upper end of the steam generation chamber at a point above a level at which water would rest in a lower portion of the chamber; (c) heat pipes, each heat pipe having a lower first end located within the means for confining the fluidized mass of particles and an upper second end located within the steam generation chamber.
