Apparatus for the cooling of solid residues of gasification

Claim 1

Apparatus for cooling the solid residues of gasification from a reactor operated at a pressure above atmospheric for the gasification of carbonaceous materials, which apparatus is disposed below the reactor and, together with the reactor, forms a pressure system with the reactor, said apparatus having an upper region and a lower region, said upper region of the cooling apparatus being substantially chutelike, at least some of the wall surface of said apparatus defining a cooling chamber comprising pipes through which a heat exchange medium can flow, elongated guide means positioned centrally of said cooling chamber and extending in the direction of flow of said residues of gasification substantially the length of said chamber from said upper region to said lower region, thereby forming an annular passage in said chamber through which said residues flow, said cooling chamber being provided with a first feed line for introducing a cooling liquid directly into said upper region of the cooling apparatus and into the solid residues located therein, a temperature sensor disposed downstream of this location in said upper region in the direction of flow of the residues of gasification to be cooled, and said lower region of the cooling apparatus being provided with a second feed line for introducing a gas directly into said lower region of the apparatus.
