ABSTRACT:
A power plant integrated with coal gasification includes an oxygen plant for separating oxygen from air and a coal gasification plant for producing a combustible gas by reaction of coal with a gasifying agent containing at least oxygen as an effective component. The combustible gas is supplied as a fuel to a gas turbine, and a portion of compressed air is bled from an air compressor for gas turbine at the outlet or at the intermediate stage of the air compressor, and divided into two portions, one of which is supplied as feed air to the oxygen plant, thus eliminating the need for a feed air compressor, and another of which is mixed with the oxygen from the oxygen plant to prepare oxygen-enriched air, which is supplied to the coal gasification plant, thus reducing the capacity of the oxygen plant.
