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.
