Problems solved by technology

In this case, however, the gas turbine is overfired, i.e. the actual turbine section inlet temperature may be higher than the maximum permissible turbine section inlet temperature
Conversely, if the compressor inlet temperature is measured to be lower than the actual temperature, the combustion in the gas turbine is not sufficient
[0008] Excessive combustion of gas turbines can lead to overheating of components subjected to hot flue gases and thus to a reduction in their life, or also to damage
Conversely, incomplete combustion in a gas turbine results in a loss of power

Embodiment Construction

[0025] FIG. 1 schematically shows a gas turbine plant for converting fossil energy into electrical energy by means of a gas turbine 1 and a generator 2 connected thereto. The stationary gas turbine 1 essentially has a compressor 3 , a combustion chamber 5 and a turbine section 7 . Compressor 3 is connected to turbine section 7 and generator 2 via a common rotor shaft 10 .

[0026] During operation of the gas turbine 1 , air is sucked in and compressed by the compressor 3 through a suction chamber 11 . In a burner, the compressed air is mixed with a combustion medium B which can be delivered via a shut-off device 8 and is fed to the combustion chamber 5 . This mixture is combusted during operation of the gas turbine to form a hot flue gas H which then flows into the turbine section 7 . The hot flue gas expands in the turbine section 7 to perform work and simultaneously drives the rotor shaft 10 . The hot flue gas H then leaves the gas turbine 1 as exhaust gas and enters an e...

Abstract

The gas turbine (1) has an injection unit (9) for the injecting of a fluid (W) into an air flow (L) drawn in by a compressor (3). A temperature measuring device (MLU) to record the temperature of the air flow is installed in front of the injection unit. The temperature (TV1) of the air flow at the inlet (12) to the compressor is calculated by means of the measured temperature (TU). An air moisture measuring device (MFU) in front of the injection device determines the moisture in the air flow. Independent claims are also included for the following: (a) a temperature measuring device to record the temperature of the air flow in front of the compressor of a gas turbine; and (b) a control system for the hot gas temperature of a gas turbine.

Description

[0001] This application is a divisional application of Chinese Patent Application No. 200480007518.2 with the filing date of March 25, 2004 and the title of the invention is "Temperature Measuring Device and Means for Adjusting Hot Flue Gas Temperature of Gas Turbine". technical field [0002] The invention relates to a regulating means for regulating the temperature of the hot flue gas of a gas turbine, in particular a stationary gas turbine for power generation. Background technique [0003] It is known to use stationary gas turbines to generate mechanical energy, which is usually converted into electrical energy by means of a generator. For this purpose, in a gas turbine, a fossil fuel is combusted together with an air stream compressed by a compressor to form hot flue gas, which is then expanded in a turbine section on the rotor to perform work. Therein, the gas turbine is operated in such a way that sufficient energy is delivered on the rotor shaft for the generation of...
