Abstract

PURPOSE: To extend the life of a gas turbine longer with lessening influence of thermal stress at the time of ignition by controlling fuel control signals to the gradient of allowable heat in the gas turbine at the time of warming-up drive.
CONSTITUTION: When ignition is confirmed by a flame detector, a contact 28FD is closed, a relay 18 is excited, and further excitation covers a temperature gradient function generator 13 and a logic/analog converter 14. Output from the converter 14 passes through a low value priority diode 16 and determines potential of a control bus 17. Output signals from a thermocouple 11 for measuring exhaust temperature are applied to a mv/V amplifier 12, its output signal B and output signal A from the generator 13 are applied to a comparator 15, which are made into output C passing through the diode 16 and applied to the control bus 17. And for example, in case where exhaust temperature in the gas turbine is smaller than the gradient of allowable temperature, the output C takes the maximum value, fuel control signals select output signals from the converter 14 by the diode 16.
