摘要： The valve includes an inflatable seal element (86) located in the housing seat and a gas-pressure-purge arrangement (116,118,123,124,111,112). The inflatable seal element (86) is inflated by means of pressurized fluid to grow in size and close up clearances between gate (50) and seat, thereby establishing a gas-tight seal between the two parts, at will. This can be done, for example, after the valve has been operated to close (slide gate (50) driven into the valve housing) and when a gas-pressure-tight seal is desired. Prior to this event, the gas-pressure-purge arrangement (116,118, 123, 124, 111, 112) is activated to blast-off solid particles from the gate surfaces where these make contact with the inflatable seal element (86). Furthermore, the inflatable seal element (86) can be deflated to shrink in size, thereby providing increased clearance between gate (50) and seat, when desired. This can be done just prior to the moment when the gate (50) is to be operated (driven out of the housing) to open the valve.

摘要： An apparatus is disclosed for feeding a continuous supply of carbonaceous material into a pressurized reactor for producing a product gas from the material and which contains toxic and flammable gases. The apparatus comprises a first rotary gas lock (13) for receiving the material from ambient atmospheric condition. The first lock (13) is supplied with a flow of nitrogen as a sealing gas to prevent air from entering the lock and the apparatus. The first lock (13) transfers the material to a second rotary gas lock (14) which in turn transfers the material to a screw conveyor (42) for delivery to the interior of the reactor. The second lock (14) is supplied with a flow of a clean product gas as a buffer gas. The clean product gas supplied to the second lock (14) is at a pressure greater than the pressure in the reactor and prevents flow of gases from the reactor to the apparatus. An exhaust (51) is maintained between the first and second locks which draws off nitrogen and clean product gas with the nitrogen and product gas constituting a noncombustible mixture of gases in the exhaust. Means are provided for preventing entrainment of particulate material between the first and second gas locks.
