Abstract

PURPOSE: To prevent occurrence of various troubles due to maladjustment for the deviation of the combustion temperature, by empolying an arrangement capable of controlling the deviation of the combustion temperature of a plurality of combustors to be lower than a predetermined value promptly in controlling combustion of a gas turbine having a plurality of combustors.
CONSTITUTION: Combustion temperatures in respective combustion barrels of a plurality of combustors 4aW4c are detected by thermocouples 12aW12c disposed at the outlet side of the combustors 4aW4c, that is, on the inlet side of the first-stage nozzle, and temperature signals 13aW13c are given to an arithmetic unit 14. From these input signals, the arithmetic unit 14 calculates the average value and the deviation of the combustion temperatures of combustors 4aW4c. Control signals 15aW15c based on the deviation of the combustion temperatures are afforded to fuel controlling means 19aW19c disposed respectively in fuel supply pipes 18aW18c, for controlling those fuel controlling means connected, for instance, to combustors the combustion temperatures of which are low to increase the fuel flow relatively. Therefore, it is enabled to control the deviation of the combustion temperatures of combustors 4aW4c to be lower than a predetermined value.
