초록

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, ...
