Abstract: 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).

Abstract: A process and device for the gasification of liquid or fine-grain solid fuel materials with the aid of oxygenous, gaseous gasification agents in a reactor is described. Liquid slag is separated on the walls of the reactor. The synthesis gas is generated in a first reaction chamber arranged in the upper part of the reactor and the feedstock is fed to the upper part. Liquid slag precipitates on its lateral walls, with free downflow and no solidification of the slag surface. The lower side has a hole with a slag drop-off edge, from which the generated synthesis gas can be withdrawn in downward direction and the liquid slag can drop off the edge. A second chamber which is delimited by a water film is located under the opening and used to keep the synthesis gas dry and cool. A third chamber is adjacent to the bottom of the second and fed with water to cool the synthesis gas.
