METHOD FOR CONTROLLING GAS TURBINE POWER PLANT, GAS TURBINE POWER PLANT, METHOD FOR CONTROLLING OVEN FOR GASIFICATION OF CARBON-CONTAINING FUEL, AND OVEN FOR GASIFICATION OF CARBON-CONTAINING FUEL

摘要

PROBLEM TO BE SOLVED: To provide a method for controlling a gas turbine power plant, in which the amount of heat generation of produced gas produced in an oven for gasification of carbon-containing fuel can be kept constant, the gas turbine power plant, a method for controlling the oven for the gasification of the carbon-containing fuel, and the oven for the gasification of the carbon-containing fuel.;SOLUTION: The gas turbine power plant includes: a coal-gasification oven 3 which comprises a coal-gasification oven body 3a for gasifying the carbon-containing fuel to turn it into the produced gas, and a water-cooled wall duct 3b provided in the coal-gasification oven body 3a and subjected to introduction of water as a cooling medium; a gas turbine combustion device 5a which combusts the produced gas to turn it into combustion gas; a gas turbine 5b which is rotatively driven by the combustion gas produced by the gas turbine combustion device 5a; and a generator G which generates electricity by the rotational driving of the gas turbine 5b. In the coal-gasification oven 3, the supply of the fuel is controlled depending on the amount of heat absorption of the cooling medium introduced into the water-cooled wall duct 3b.;COPYRIGHT: (C)2013,JPO&INPIT
