Abstract: In known separators, some of the solids trapped in the trapping chutes may be prevented from being discharged at the wall due to by-pass currents at the lower end of the trapping chutes. To improve the discharge of the separated dust, the lower end of each trapping chute that is adjacent to the wall is provided with an outlet channel piece extending to the wall and having a slot-like outlet opening resting at the wall and opening downward; and sheet metal deflectors are arranged between the outlet channel pieces of each layer of trapping chutes at a distance from each other and from the wall, which form between them delimit slots for the passage of gas. The separator is preferably used to separate solids from the ascending flue gas in a fluidized bed furnace.

Abstract: A method and apparatus for burning carbonaceous materials in a fluidized bed reactor comprising a bottom region and a top region, and containing a fluidized bed, with the heat of combustion being dissipated at least via wall cooling surfaces, and comprising a recirculation system, including a labyrinth separator for recirculating the separated solids to the bottom region of the fluidized bed reactor. The solids are separated from the rising flow of flue gas by the labyrinth separator, which is disposed directly in the top region of the fluidized bed reactor, and are conveyed in the reactor itself along the wall cooling surfaces and are supplied to the bottom region of the reactor, either freely or in closed or partly or completely open recirculation passages. The main area of application is with a steam generator.

Abstract: A method of and apparatus for providing coal dust to a reaction chamber, especially in the process of producing low-sulfur coke dust and gas by gas extraction and partial gasification of coal dust in a reaction chamber for partially combusting coal dust. Coal dust and a first stream of combustion gas are combined and passed through a central conduit to a reaction chamber. A second stream of combustion gas can be selectively subjected to swirling motion and can be combined with the stream emanating from the central conduit. The degree of swirl of the first stream and the second stream of combustion gas is used to control distribution of the gas-solids mixture in the reaction chamber and to control the path of the gas-solids mixture leading into the wall of the reaction chamber.
