FIELD: chemistry.SUBSTANCE: invention relates to the chemical industry and is intended for the gasification of ash-containing fuel with oxygen-containing gas. A gasification reactor (1) contains a reservoir under pressure (2), inside which a reaction chamber (4), formed by a membrane wall (3) is located. The chamber (4) is connected to a chamber (11) for gas cooling by a narrowing transition channel (7). The transition channel (7) includes vortex-reducing cooled ribs (9), under which placed is a fillet with a wavy surface, transiting into the reduced in diameter first cylindrical wall, which has the first edge (18) for drops flowing off. The first cylindrical wall is surrounded by the increased in diameter second cylindrical wall, at the end of which in the direction of gravity, formed is the second edge (10a) for flowing off of slag drops. The second cylindrical wall is installed with a possibility of displacement in height relative to the first edge.EFFECT: invention makes it possible to provide optimal slag flowing off.5 cl, 3 dwg |
