Filed: 1980-06-06
Abstract: A hot raw gas stream, as produced by the partial oxidation of a solid carbonaceous fuel such as coal, is partially cooled and cleaned to remove entrained solid matter and slag in an apparatus comprising a closed cylindrical insulated vertical pressure vessel (46) containing a lower quench chamber (48) in communication with an upper solids separation chamber (49) separated by a choke-ring (50). The hot raw gas stream introduced through inlet (45) is cooled in the lower chamber by impingement and direct heat exchange with an oppositely directed coaxial stream of cooled, cleaned, and compressed recycle quench gas introduced through inlet (55). The cooled gas leaving the turbulent lower chamber passes up through a choke- ring (50) into the comparatively calmer upper chamber counter- currently with solid slag droplets which separate out by gravity. Residual solid particles are removed from the gas stream by at least one cyclone separator (56) located in the upper chamber. A portion of the gas stream leaving the vessel, with further cooling and with or without further cleaning downstream is recycled back to the vessel through inlet (55) for use as said quench gas. Slag particles and other solid matter that are separated within the pressure vessel are removed at the bottom outlet (52) of the lower chamber. <IMAGE>
