With the continuous development of gas turbine technology, the temperature of turbine inlet gas also increases, and the working environment of turbine blades is even worse. The service life of turbine blades is an important factor that determines the service cycle of gas turbines. To prevent high temperature thermal erosion damage on the surface of blades, It needs to be cooled efficiently. The development of turbine blade surface temperature measurement technology not only provides data support for the optimal design of turbine blade cooling structure, but also enables real-time monitoring of turbine blade surface temperature, avoiding operation above safe temperatures, and ensuring safe and reliable operation of turbine blades.
Researchers at the Research Center for Heat and Mass Transfer at the Institute of Engineering Thermophysics, Chinese Academy of Sciences, have proposed a new technique for measuring the surface temperature of turbine blades, and conducted a large number of experimental and theoretical studies on the complex thermal environment inside the turbine. The spectral radiation characteristics of the material surface have been designed and established. The measurement platform has studied in detail the radiation characteristics of high-temperature alloy materials commonly used in blades and has established relevant databases. It has also developed a calculation program for gas spectrum radiation characteristics and designed and established an experimental verification platform. While studying the characteristics of gas radiation, the experiment verified that Calculate the reliability of the program; design and develop a reverse Monte Carlo method radiation calculation program, greatly improving the radiation calculation speed; based on the inverse Monte Carlo method radiation calculation program, studied the influence of various parameters on the accuracy of temperature measurement, Accurate measurement of turbine blade surface temperature under complex radiation conditions provides support.
Based on the above theoretical and experimental research, a turbine vane temperature measurement prototype was designed and manufactured. The steady-state output and dynamic characteristics were analyzed. Based on this, a portable temperature measurement system suitable for engineering applications was developed. The laboratory calibration calibration and testing work has been completed. The indicators meet the turbine blade temperature measurement requirements, and individual indicators even reach the international advanced level, marking the R & D team has broken through the high-frequency measurement process noise interference, mastered the turbine blade surface temperature Measuring key technologies. At present, it is preparing to further test and verify this technology on the relevant experimental platform of the industry institute.
The relevant research results have applied for 3 invention patents, of which 2 have been authorized.
