Abstract

PURPOSE:To make a proper gas flow rate feedable to a gas turbine by controlling it so as to cause longitudinal differential pressure in a fuel flow control valve to become constant at the time of low load. CONSTITUTION:An inlet pressure signal of a gas turbine combustor detected by a pressure detector 50 and a setting signal out of a constant setter 52 setting minimum differential pressure in front and in the rear of a fuel flow control valve 7 are inputted into an adder 51. And, each adding signal of both and a gas flow velocity constant pressure setting command signal outputted out of a multiplier 34 are added to a high-value preferrer 53. Both these high-value signals are added to an adder 38 in a gasifying furnace control part 37, compared with an actual gas pressure signal detected out of a gas pressure detector 39, and a coal gas flow regulating valve 2, an air flow regulating valve 3 and a steam flow regulating valve 4 are all controlled by the deviation signal. With this constitution, gas pressure is set so as to cause a gas flow velocity to become constant as well as to cause longitudinal differential pressure in the fuel flow control valve 7 to become constant as well.
