Major Progress and Achievements in 2013
Research on dense transport bed gasifiers: In a pressurized drop tube furnace, the effects of coal type, temperature, pressure, and pulverized coal particle size on coal pyrolysis, the physical and chemical characteristics of coke and coke reactivity were examined at high heating rates. A chemical reaction model for a transport bed gasifier was established and verified by experimental results and data in literature. Preliminary research was performed to study the effects of temperature and pressure on the fluid-dynamic characteristics through experimentation and numerical simulations. The construction and commissioning of the 5 TPD pressurized dense transpor bed gasifiers have been completed. The experimental devices of gas-solid hydrodynamics, coal feeding and ash discharge have been put into experimental study. The installation of main devices, such as a pilot-scale gasifier, heat-recovery boiler, gas scrubbing tower and desulphurization tower were completed. The installation of pipeline was 60% finished, while the installation of instrumentation and electrical devices was 50% finished.
In the development of heavy-duty turbine combustors, IET completed the idle load testing for a low - and medium-calorific value fuel-using R0110 heavy-duty gas turbine plant. The QD128 gas turbine has begun grid-connected power generation and passed a 96 hour running assessment test at full capacity. An exploration study on new concept MILD combustion chamber was successfully completed, and applied successfully for the 973 Young Scientists Project. Low emission flameless combustion design scheme based on vortex stability has been improved, engineering drawings design and test pieces processing has been finished. A study was carried out on the overall program design of a low emission natural gas combustor, an optimized solution for the nozzle unit was derived, and experimental and model validation was obtained. The preliminary overall schematic of a low pollution steam injection combustor was derived, as was an optimization scheme for a single nozzle, and the combustor design and processing was completed.
With regard to research on compressor stability, the self-circulation air injection system has been proven to be valid for extending the stall margin of fans/compressors. The unsteadiness and stability enhancement mechanism of tip clearance flow for single circumferential grooves at various axial locations have been clarified, based on which, the preliminary design method of circumferential grooved casing was then proposed. The lab has built a low-speed large-scale compressor rig with a dynamic data acquisition system. A total-pressure probe with high responding frequency and spatial resolution, used for instability measurements of wide-angle flow, and a micro high-frequency dynamic entropy probe have been invented. The lab has also completed a fan/compressor rig with inlet distortion for the experimental investigation of flow instability.
As for advanced power cycles and energy systems, researchers at the center have conducted experimental study on hundred kilowatt-scale prototype systems of HAT cycle, determined the technical processes of water recycling, confirmed that the alkali metal ion contents, including potassium, sodium, and calcium, in water recycling from the exhaust can satisfy the cycle’s requirements. System control strategy and control systems were improved. The researchers improved the models of key components for system integration software platforms, established a quasi-one-dimensional transport bed gasifier model and a continuous heavy-duty gas turbine expansion turbine cooling model. Researchers also carried out a comparative study of Sino-US IGCC cost estimation models and economic evaluation methods. A study wsa conducted on the potential for the future development of IGCC thermodynamic performance and the contribution of individual technology breakthroughs were obtained and system integration to IGCC power efficiency was improved. IET researchers also conducted thermodynamic performance assessments and comparisons of IGCC with solid cycling process for CO2 capture at high and medium temperatures.
Regarding energy saving and environmental protection, the VAM emissions reduction and usage project, one of the subtasks of the CAS Knowledge Innovation Project “emission reduction technology development and demonstration”, had been completed, and passed its acceptance check. Blade aerodynamic design and three-dimensional CFD calculation for a 12 MW steam turbine high and low pressure cylinder, heat balance and valve characteristic calculation in design and off-design working conditions, and strength checks of the blades has been finished. The overall performance calculation program of a dish solar air turbine power generation system has been accomplished; and the design and CFD examination of a centrifugal compressor with pressure ratio 5.1 and centripetal turbine with pressure ratio 3.7 were carried out.
The National 863 major project “coal gasification-based poly-generation demonstration project” passed its acceptance check by the Ministry of Science and Technology (MOST). Results of the project showed that the R&D and demonstration of the key technologies of coal gasification-based poly-generation and IGCC have made significant progress in China, building the capabilities for innovating new technologies, and systems and engineering integration.
