Project and Major Achievement
The center undertook the national major science and technology infrastructure project “High-Efficiency and Low-Carbon Gas Turbine Research Facility” and led the basic research project of national “aeroengine and gas turbine” major project, named “the fundamental research on wet gas turbine cycle technology” and “Combustion mechanism and verification of coal to fuel gas in IGCC heavy duty gas turbine combustor”.
In terms of gas turbines, the automatic generation algorithm of chemical reactor network has been developed, realizing rapid prediction of NOx emissions in the combustion chamber, with an error of <10% compared with the test values; the measurement and prediction method of combustion oscillation in gas turbines based on the measurement of flame dynamic characteristics, the calculation of flame describing function and the prediction of one-dimensional thermoacoustic oscillation have been preliminarily established, and the time lag analysis method based on the spatial distribution of flame fronts has been developed; the conceptproof of fuel flexibility for the MILD burner has been completed; the developed natural gas HAT and IGCC micro-mix combustion chambers have completed the full-temperature and high-pressure test validation of the F-class parameters, and stabilized low-emission combustion was achieved, where NOx emissions were both less than 10 ppm@15% O2; and the lowemission scheme design and test validation of the hydrogen-enriched fuel gas combustion chamber of a certain type of industrial combustion engine have been completed.
In terms of supercritical carbon dioxide (S-CO2) power cycle technology, the mechanical design of the MW-level TAC Unit for the power generation system using low-temperature heat sources and its performance verification for high-temperature operation conditions have been completed. As for the expansion of application scenarios, a further design of MW-level TAC Unit for high-temperature heat sources has been completed. The MWlevel S-CO2 cycle test rig has taken on the experimental testing tasks of S-CO2 components for multiple domestic users. In response to the power generation needs of offshore platforms, scheme research is ongoing for a demonstration project of S-CO2 power generation using gas turbine waste
heat.
In terms of advanced power cycles and energy power systems, the fundamental experiments and pilot tests of biomass gasification were carried out, the behaviors of biomass pyrolysis and bio-tar cracking under different atmospheres were acquired, and the rate-determining step for char gasification reaction in gasification process were studied.
In terms of the National Major Research Infrastructure Project of HighEfficiency and Low-Carbon Gas Turbine Research Facility (HiGT), the compressor, combustion chamber, turbine, supercritical carbon dioxide, and other test rigs have completed process installation and single-unit commissioning, and entered the joint commissioning stage. Some test rigs have reached the process acceptance index. The CP01 single/multi-stage compressor test facility has successfully achieved operation at maximum design rotational speed. CTF#1 combustion chamber test rig has supported the development of combustion chamber components for multiple models of independently developed F-class heavy-duty gas turbines, and it was the first time to carry out and complete the full-temperature and fullpressure test for hydrogen blend natural gas (max. 40% vol.) of F-class heavy-duty combustion chambers. The TB-01 test bed has conducted the first full-temperature and full-pressure cooling efficiency tests on the firststage stator and rotor blades of an F-class heavy-duty gas turbine in China. The TB-02 test bed has completed its first ignition test. The TB-03 test bed has finished the integration test and achieved the design specifications requirements. The main pump and compressor of the GC01 supercritical carbon dioxide test bench have completed the tests and have reached the design parameters. Furthermore, the whole system of the power cycle has carried out hot tests with load. High-temperature compressed air source was officially commissioned; phase I of the fuel system was commissioned and provided gas supply for the test benches.
