MHI achieves 1,600°C turbine inlet temperature in test operation of efficient J-Series gas turbine.
27 May 2011. Mitsubishi Heavy Industries, Ltd. (MHI) has achieved a turbine inlet temperature of 1,600 °C—which it calls the world's highest—with the company's advanced J-Series gas turbine.
I suppose it's Fahrenheit - that would make around 1400 deg C, which is realistic for nowadays gas turbines
For non cooled blades for Waspaloy Tmax = 900K and peripheric velocity < 500m/s
Japan is working towards 1700 C TIT. See MHI https://www.mhi.co.jp/technology/review/pdf/e451/e451015.pdf
Dear Guelailia Ahmed,
The turbine inlet temperature (TIT) is an important operating parameter that affects the performance of the integrated system. The turbine inlet temperatures of gas turbines have increased considerably in recent years and will continue to do so. This trend has been made possible by advances in materials and technology, and the use of advanced turbine blade cooling techniques. The output of the turbine is improved by increasing the critical parameters of temperature and pressure; this can only be achieved using new materials of construction and optimised cooling and layering technologies for cooling and coatings. Gas turbine inlet temperatures of almost 1,500 °C (17 bar) are necessary in order to achieve a gas and steam efficiency of 65%. MHI has achieved the world's highest turbine inlet temperature of 1,600 degrees Celsius (°C), with the company's most advanced”J-Series” gas turbine.
Hope it help you out.
