Project and Major Achievement
For the "Ship Compressor" project, we has completed an 8-stage scaled compressor experiment with a stability margin of 30.7% under low operating conditions (70% speed), completed the test run of the 17th stage axial compressor gas generator with a design point adiabatic efficiency of 87.1%, developed aerodynamic design methods and platforms for singleaxis multi-stage axial compressors, completed the thematic achievement review, completed the inspection of the second milestone node of the project, completed the project acceptance and performance self-evaluation review. The "Long Life Turbine Blade Gas Thermal Coupling" project has broken through the high-efficiency and long-life cooling design technology for largesized turbine blades of heavy-duty gas turbines with an initial temperature of 1600°C. It has achieved an average comprehensive cooling efficiency of over 0.65 in the high-temperature and high-pressure test of the first stage stationary blades of the turbine under the condition of no more than 10% cold air volume.It has completed the second milestone inspection of the project, completed project acceptance and performance self-evaluation review. The project of "Long term Service of Coated Turbine Blades for Gas Turbines" has completed milestone node inspection, 930°C endurance test for over 4000 h, fatigue test for 960,000 cycles (3900 h+), and developed a software for life calculation management. The National Key Research Instrument Development Project of the National Natural Science Foundation of China has proposed new principles and key technologies for high-frequency dynamic pressure measurement of plasma, timely prediction of instability precursors, and adaptive expansion and control of low entropy production. The experimental device for monitoring and controlling flow instability in high load compressors has been developed and accepted. The key technology and demonstration of low-calorific-value fuel gas turbine combined cycle power generation in the coal pilot project completed the design of a dry low emission combustion chamber scheme for low calorific value fuel and the experimental verification of a single head model combustion chamber. The combustion efficiency ≥ 99.5% and the NOx ; "> emissions ≤ 50 mg/Nm3. the design of a digital twin model for medium to low calorific value fuel gas turbines was completed.
Technology Transfer
In 2023, there are a total of 24 ongoing research projects. We have got 9 new projects, including 1 general project of National Natural Science Foundation of China, 1 pre research project, 1 key deployment project of the institute, 1 "Two Machine" special project, and 5 commissioned projects by enterprises, with funding of 53.6992 million CNY received.
Qingdao Zhongke Guosheng Power Technology Co., Ltd. was established in October 2017 with a total investment of 1 billion CNY. The main shareholders are the Institute of Engineering Thermophysics of the Chinese Academy of Sciences, Chengfa Investment Group Co., Ltd., Qingdao Military Civil Integration Development Group Co., Ltd., etc. The company mainly engages in the research and development, complete machine assembly, trial testing, complete machine and spare parts sales, and operation and maintenance technical services of military civilian dual-use 40 MW light gas turbines such as ship propulsion, natural gas distributed energy generation, large compressors (pumps), and offshore oil and gas platforms. It is a typical high-end equipment enterprise for military civilian integration. In 2023, the laboratory and the company jointly completed the installation and commissioning of the test platform combining gas turbine, generator and power consumption system, and achieved stable operation of a 30 MW gas turbine under load for 100 hours. The power system test platform can support the load testing of lightduty gas turbines with a power range of 20−50 MW in the future, providing solid conditions for the development of subsequent models.
