Abstract:
The paper deals with a non-intrusive pyrometric technique for the real time measurement of the Gas Turbine inlet temperature (TIT), which is a critical parameter influencing both material and coating lifetime of turbines as well as their efficiency. The proposed technique relies on the detection of the radiation emitted in a narrow wavelength band by the CO2 molecules present in the combustion gas. Preliminary results will be presented relevant to measurements carried out both during laboratory tests and on a full scale test rig capable of reproducing a typical high temperature and high pressure gas turbine environment.
