Gasification reactor having direct or indirect support at coolant inlet lines or mixture outlet lines

摘要

A cooling shield is to be made available, in particular within the pressure container, with conical regions for the exit of gas or slag, in a gasification reactor (1) for producing crude gas containing CO or H2, having a pressure container (2) and a reaction chamber (4) formed by a membrane wall (3) of cooling pipes, wherein an annular space is formed between the inner wall of the pressure container (2) and the membrane wall (3), wherein elements such as burners (17) or the like are provided, which elements horizontally pass through the pressure container wall in the membrane wall substantially on the same plane (18), wherein the suspension or connection between the cooling shield and pressure container (load removal) is optimized, while avoiding difference expansions.;This is achieved in that, for removal of the load on the membrane wall (3), direct or indirect support takes place at the cooling inlet lines (5) or mixture outlet lines (14).

主权项

1. A gasification reactor for producing crude gas, containing CO or H2, by gasification of ash-containing fuel with oxygen-containing gas, at temperatures above the melting temperature of the ash, said gasification reactor comprising:
a pressure container comprising an inner wall; a membrane wall forming a reaction chamber and comprising a first set of cooling pipes; an annular space formed between the inner wall of the pressure container and the membrane wall; burners horizontally passing through the inner wall of the pressure container and the membrane wall, substantially on the same plane and creating heating surfaces; and coolant inlet lines and mixture outlet lines; wherein the membrane wall is supported directly or indirectly at the coolant inlet lines or the mixture outlet lines; and wherein the coolant inlet lines and the mixture outlet lines enter the inner wall of the pressure container within the plane defined by the burners.
