ABSTRACT:
A temperature control device in a gas-turbine unit of a single-shaft or twin shaft type for the turbine of the unit, comprising two transmitters, one of the two transmitters being intended for controlling the pressure differential across a first orifice mounted in the pipeline upstream of the compressor of the gas-turbine unit, whereas the second of the two transmitters is intended for controlling the pressure across another orifice mounted in the pipeline that connects the pipeline upstream of the turbine with the pipeline upstream of the compressor, provision being made for disposing a valve of an adjusting device for sensing the temperature in said pipeline upstream of the compressor, the variations in the position of the valve being sensed by the second pressure drop sensor, the two pressure differential transmitters being connected in such a manner than their output signals are added together and the resultant signal is fed to an actuating device for changing the flow of fuel to the combustion chamber to control the gas temperature of the gas supplied to the turbine, two identical temperature control devices as described above being used for a twin shaft type gas turbine unit, each one of the temperature control devices being intended for controlling the temperature upstream of either one of the two turbines of the unit.
