Title:
COAL GASIFICATION COMBINED CYCLE POWER GENERATION PLANT
Document Type and Number:
Japanese Patent JP3658497
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a coal gasification combined cycle power generation plant which can divide its throw in amount suitably and restrain the generation of NOx and carbon monoxide to low, while increasing the output of a gas turbine and the thermal efficiency of the plant much more, when nitrogen gas N2 is thrown in a gas turbine combustor.
SOLUTION: In this coal gasification combined cycle power generation plant, a nitrogen supply system for supplying nitrogen gas N2 separated by the air separation device 37 of a coal gasification plant 28 to the gas turbine combustor 30 of the gas turbine plant 28 is divided into two systems 38, 39 and the one nitrogen supply system 38 is connected to the fuel injection part of the gas turbine combustor 30, while the residual nitrogen supply system 39 is connected to the rear flow side of the gas turbine combustor 30.
