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 “aero-engine 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”.
For gas turbine, we investigated the effect of fuel composition and nozzle geometry parameters of micro-mix burners on the flame structure, thermoacoustic instability, and NOx emissions. We completed the performance verification of low-NOx micro-mix model burners with high hydrogen content syngas and pure hydrogen fuel under atmospheric pressure. A study on the organization of hydrogen-oxygen combustion has been conducted. The influence of the H2-O2-steam mixing quality on combustion efficiency has been investigated using a well-established CRN model, and the multi-component mixing mechanism has been revealed. The high-pressure experimental investigation of an HMM02 humid air combustor has been successfully carried out, and the effect of 25% hydrogen mixing on combustion characteristics has been investigated experimentally. We developed an IGMM01 coal gas combustor test piece and conducted an experimental investigation on thecombustor performance under pressurized conditions. We numerically designed and investigated a combustor with hydrogen-oxygen micro-mix combustion.
Regarding advanced fuel conversion, the chemical structure of pyrolyzed chars from solid hydrocarbons can be predicted by BMCP model modifiedusing restricted conditions on different phases. The modified BMCP model can be used to determine the operation conditions for different sorts of feeds. The system model of solid hydrocarbon gasification process driven by renewableelectricity has been established, and the exploring experiments were carried out.
With respect to advanced power cycle and energy & power system, the experimental commissioning of MW-level S-CO 2 generator set has been completed in Hengshui, Hebei Province, which has reached the project targetand passed the project acceptance. We carried out the preliminary research on a compact S-CO2 power generation system and completed the preliminary design of an integrated S-CO2 coaxial power generation mainframe. In termsof cycle optimization, we conducted research on the steady-state and dynamic characteristics of S-CO2 cycle variable load through CO2 inventory control, and obtained the load lifting and lowering characteristics. Aiming at gas turbinesand combined cycles, we conducted research on ways to further improve gas turbine performance, proposed specific technical ways and quantitative contributions to improve efficiency of gas turbines and combined cycles, andformed an efficiency improvement potential map. We completed on-site testing of technical indicators including power generation efficiency, NOx emissions, and comprehensive energy efficiency of combined heat and power generationfor 100 kilowatt level humidified gas turbine. In terms of deep purification of flue gas and water heat recovery and utilization, we basically completed the commissioning of the 10000 m3/h flue gas industrial side line test demonstrationdevice, and the operating parameters have reached the design indicators. The demonstration device will be upgraded. Its performance will be proven through long-term operation of the demonstration device.
The national major science and technology infrastructure project "High-Efficiency and Low-Carbon Gas Turbine Research Facility": we carried out the installation and commissioning of compressor, combustion chamber,turbine and supercritical carbon dioxide test platforms. The load test of the 10 MW class gas turbine for the high-efficiency new cycle test platform was completed. The main equipment including air intake system, regenerator and flue gas/water heat exchanger, humidifier and aftercooler have been processed and manufactured, and will be installed. The high-pressure centrifugal compressor unit has completed commissioning, performance assessment and put into use. We completed the installation and commissioning of the natural gas compressor unit. The control and data center (Phase I) of test platform entered the internal testing and operation phase. The coal gas preparation system entered the commissioning stage. Lianyungang outdoor pipeline (Phase II) was under construction. Shanghai air source system completed installation.

International Cooperation and Exchange
The center continued to promote substantial cooperation with US members of U.S.-China Clean Energy Research Center on Advanced Coal Technology Consortium (CERC-ACTC) and of U.S.-China Clean Energy Research Center on Energy and Water Track (CERC-WET). The center participated 2 international cooperation projects supported by the Ministry of Science and Technology, called “Carbon capture, storage, utilization, demonstration and new generation of technology development” and “key technologies of energy and water bond and efficient green utilization” respectively. Joint team carried out research on kinetics of key processes of coal gasification based on calcium absorbent, efficient and water-saving IGCC/IGFC power plants, water and heat simultaneous recovery technology. Both projects have passed the acceptance inspection. The researchers participated in Paving the Way for Green Hydrogen in Advancing Circular Economy: Stakeholder Management for Capacity Building and Strategic Communications for Advocacy (APEC2023), 2023 GPPS International Technical and presented papers.
