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).

With a device for influencing the flow, particularly in a horizontal connecting pipe (1) between a coal gasification reactor and a gas cooler/purifier, a solution is supposed to be created, whose task consists in being able to reduce or shut off the gas stream of a hot synthesis gas, if necessary, without being exposed to the great stresses caused by the corrosiveness and the high temperatures, while avoiding complicated valves or regulation devices.This is achieved by means of a Venturi constriction in the flow path of the gas in the pipe (1), as well as a flow cone (4a) positioned on a push rod (4) that is disposed centrally, whereby a connecting rod system (4b) that is guided to the outside is provided to move the push rod (4), whereby the connecting rod system (4b) that moves the push rod (4) is formed by a connecting rod arm guided in a dummy connector and a connecting rod arm guided out of the dummy connector (8) by way of a packed gland (6).

It is supposed to be possible to achieve an essentially uniform water film protecting the corresponding metal panels, in 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, wherein a reaction chamber formed by a membrane wall through which cooling medium flows, a transition area as well as a quench chamber with a slag collection container that follows in the direction of gravity are provided within a pressure container.This is achieved in that, in addition to a device (14, 15) forming a water film (16) in the quench chamber (11), at least a part of the cylinder forming the quench chamber wall (17) is designed with a double wall and with a coolant overflow (21) for additionally wetting (18) the inner surface of the quench chamber wall (17), and a tangential coolant supply (20) in the bottom area of the double walled cylinder (19) which is closed at the bottom.

摘要:
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, has a reaction chamber formed by a membrane wall through which coolant flows, within a pressure container, is provided, with a narrowing transition channel into a gas cooling chamber, and spin-reducing, cooled bulkheads in the transition channel. The, wall that carries the bulkheads makes a transition, below the bulkheads, into a cylinder wall that is reduced in diameter, by way of a step having a corrugated surface. The cylinder wall, which is reduced in diameter, is enclosed by a further cylindrical wall, which is enlarged in diameter, which wall forms a second slag drip edge at its end, in the direction of gravity. The further cylindrical wall is disposed to be adjustable in its vertical position, with reference to the first drip edge.
