Abstract

PURPOSE: To improve a thermal efficiency of a plant which performs gasification by means of an oxygen produced by an oxygen producer disposed therein, by feeding a nitrogen into a gas turbine as a working medium which is generated in a process of the production of the oxygen.
CONSTITUTION: An oxygen producing plant provides a means of cooling an air 11 to be liquefied by the effect of Joule Tomson and separately producing an oxygen 12 and nitrogen 13 because of a difference between their boiling points. The produced oxygen 12 is fed to a coal gasifying plant 2 to partially oxidize a coal 14, thereby generating a coal gas 15. After passing through a gas refining plant 13, the coal gas 15 is turned into a fuel gas 16, which is thereafter fed to a gas turbine combustor 5. On the other hand, the nitrogen 13 is mixed with an air 11 in a mixer 17, boosted by a compressor 4 and fed to the combustor 5. A burning gas 19 in the combustor 5 is delivered to a gas turbine 6 to work. When the nitrogen 13 and the air 11 are mixed, the temperature of the resultant mixture gas is reduced so that the compressor 4 is decelerated. A thermal efficiency may be increased as much as a decrement of the deceleration.
