A system and method for generating power by producing a clean gaseous fuel from a solid fuel, such as coal. A flow of oxygen enriched compressed air is formed by combining compressed ambient air from a gas turbine compressor and a flow of oxygen from a air separation unit. The coal is supplied to a gasifier, along with the flow of oxygen enriched compressed air in which the coal is combusted. The gasifier produces a flow of hot gaseous fuel containing slag and other particulate matter. The slag is removed from the hot gaseous fuel and, after processing, ...
[ I claim:] [1.] A method of generating a gaseous fuel from a solid fuel, comprising the steps of:a) compressing a first flow of air so as to produce a flow of compressed air;b) separating a second flow of air into at least a flow of nitrogen and a flow of oxygen;c) combining said flow of compressed air and said flow of oxygen so as to produce a flow of oxygen enriched air;d) directing said flow of oxygen enriched air to a gasifier and combusting said solid fuel therein so as to produce a flow of hot gaseous fuel containing particulate matter;e) cooling ...
