摘要： The present invention discloses a gasifier and/or a gasification process that provides a long, uniform temperature zone in the gasifier, regardless of the particle size, chemical composition, and moisture content of the fuel by sandwiching a reduction zones between two oxidation zones. The gasifier and/or gasification process has a char that is more energy-dense and almost devoid of moisture that affords for an additional (or char) oxidation zone with a temperature that is higher than a first oxidation zone which is closer to an evaporation and devolatilization zone. As such, the additional (or char) oxidation zone contributes to augmenting the reduction zone temperature, thereby providing a favorable dual impact in improving syngas composition and near-complete conversion of the tar.

摘要： A method and assembly for producing substantially tar free product gas from gasification of carbonaceous material. The assembly preferably includes a first stage gasifier to produce char-ash and tar laden product gas and a second stage gasifier which has a char-ash heating zone, at least one cyclone, and at least one standpipe for the purpose of allowing selective delivery of char-ash to the char-ash heating zone. A char-ash heating zone that utilizes oxidation of char-ash is preferred and this results in the heat required to convert tar, additional yield of product gas, and an oxidized, activated carbon surface to facilitate tar conversion in the riser, thereby reducing the temperature required to achieve the desired tar conversion. Alternatively, external heat is supplied to the heating zone.

摘要： A gasifier for the manufacture of producer gas has a chamber (10) for the combustion of material, the chamber (10) being provided with a plurality of tuyeres (30) for the introduction of combustion air to the chamber. The tuyeres (30) are disposed at an acute angle to the wall of the chamber (10) so that air is directed both around and upwardly of the chamber. Each tuyeres (30) is configured to produce a jet stream wherein the air swirls along the length of the stream.

摘要： The invention includes mixing gas or solid particulate fuel in a conduit segment that houses a mixing chamber. Fuel is fed through a fuel inlet port into the mixing chamber. High velocity combustion air from a blower is forced into the mixing chamber through a restricted orifice that generates a suction pressure for drawing gas or solid particulate fuel into the mixing chamber. A combustion chamber supply conduit delivers fuel from the mixing chamber into a burner.

摘要： 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).

摘要： The invention relates to an autothermal method that is used for the continues gasification of carbon-rich substances (A) in a vertical process chamber (2) having a reduction zone (12) and an oxidation zone (6), in which the carbon-rich substances calcined in the reduction zone oxidize with oxygen-containing gas (8), wherein the gaseous reaction products (15) are drawn off at the top face of the vertical process chamber, the vertical process chamber is constructed in the form of a vertical shaft furnace, through which bulk material (3), which itself is not oxidized, flows continuously from top to bottom, wherein the carbon-rich substances are added to the bulk material before entering into the vertical process chamber. According to the invention, in order to be able to produce high-quality synthesis gas having a minimal fraction of inert gas without detrimentally influencing the energy efficiency of the countercurrent gasification, carbon monoxide-containing gas is introduced as cooling gas (10) into a cooling zone (11) at the lower end of the vertical shaft furnace.

摘要： With sampling valves for gas streams or liquids, especially in coal gasification plants and with the sampling valve located close to the reactor, the functional reliability of the valve and the identity of the samples with the crude gas stream are ensured by heating and/or flushing the sampling valve. The valve has several embodiments which include features which can be used in various combinations, for example, the valve stem can include a heater, a passage for the introduction of a flushing and/or heating medium into the valve chamber. The valve housing can include a second chamber therein through which a heating medium can be circulated or by which pressure differentials on the valve chamber can be minimized.
