On the development of domestic small and medium-sized gas turbines:
1.China Aviation Development Gas Turbine Co.
The research and development of AGT series of combustion engines began in the late 1990s, when CNAD Group independently developed the third generation of aero-engines. On this basis, after a long period of technical accumulation and ground tests, CNAD has successively developed a series of gas turbine products with independent intellectual property rights. These new-generation gas turbines have a thermal efficiency of more than 30%, a comprehensive energy utilization efficiency of more than 85%, and can be used with a variety of gases and liquids, and their main performance indexes have reached the international advanced level.
● AGT-7 series gas turbines: 7MW-class gas turbines developed on the basis of the advanced aircraft engine series, which can be applied in the fields of ship power, industrial power generation and machinery drive. Among them, AGT-7A is used for distributed energy, AGT-7B is used for offshore platforms, and AGT-7C is used for emergency backup power.
● AGT-15 gas turbine: a 15MW-class gas turbine derived and developed on the basis of advanced aviation engines, which can be applied in the fields of ship power, industrial power generation, pipeline pressurization, etc., and is characterized by high thermal efficiency, compact structure, and low operation cost.
● AGT-25 gas turbine: a 25MW-class industrial gas turbine developed on the basis of naval gas turbine, which can be applied in the fields of distributed energy, pipeline pressurization, industrial power generation and so on, and has the advantages of wide range of application and high reliability.
● AGT-12 gas turbine: China's first aviation lightweight gas turbine with independent intellectual property rights, which was awarded "National Key New Product" in 2011, and can be used in the fields of distributed energy, emergency power supply, and medium and low calorific value fuels, etc., with the features of high comprehensive thermal efficiency and low operating costs.
● AGT-2 series gas turbines: gas turbines derived from domestic turboprop aero-engines, which can be used in the fields of medium and low calorific value gas fuels, hydrogen-rich fuels and combined heat and power supply, and have supplied more than 300 sets of generator sets both at home and abroad.
On April 7, 2023, the first two domestic gas turbine generator sets AGT-7B developed by CNAFGM were successfully shipped to the offshore platform engineering site after the completion of the factory inspection in the early stage, which equipped the offshore drilling platform with a strong "Chinese heart". According to CNAFGM, this unit has independent intellectual property rights of 7MW domestic gas turbine generator set, realizes 100% independent manufacturing of core parts, and will provide a whole chain of "Chinese solutions" for more offshore oil and gas industry fields.

2. Dongfang Turbine Co.
The research and development of China's first F-class 50 MW heavy-duty gas turbine (hereinafter referred to as "G50") with independent intellectual property rights began in 2009, when Dongfang Turbine set up a scientific research team and formally started the independent development of the project. After 15 years of unremitting efforts, on March 16, 2024, the G50 finished full-load test run and officially put into commercial operation in Sichuan. This marked the successful development of G50, which broke the technological blockade of more than 70 years and became the first F-class gas turbine designed, manufactured and tested completely independently by China.

G50
During the R&D process of G50, Dongfang Turbine has established an independent design system for F-class combustion turbine, obtained 136 authorized invention patents, and possessed the ability to manufacture all gas turbine components, which not only reflects China's breakthrough in the field of heavy-duty gas turbine, but also makes an important contribution to the country's energy security and the autonomy of the industrial chain.
Relying on the independent development of F-class 50MW heavy-duty gas turbine, Dongfang Turbine, while solving the key core technologies, has successfully set up the independent design system of F-class gas turbine, mastered the design method of gas turbine and core components, and initiated the development of the series of independent combustion turbines, including 15MW, 80MW and hydrogen-doped combustion turbine. The work of the company has been started.
In mid-April 2024, the production of the G15, the "little brother" of the G50, has reached an important point - the three-cylinder mating, which means that the final shape of the G15 has begun to take shape.The G15 gas turbine is based on the G50 gas turbine, and has been optimized and molded after many iterations. The G15 gas turbine is based on the G50 gas turbine and has been optimized and molded after many iterations. From the structural point of view, G15 has one less cylinder compared to the five cylinders of G50.
3. China Shipbuilding Industry Corporation (CSIC) 703rd Research Institute and CSIC Longjiang Guanghan Gas Turbine Co.
Longjiang Guanghan Gas Turbine Co., Ltd. specializes in the R&D, production and whole life cycle service of small and medium-sized gas turbines, and 703rd Institute is one of its major shareholders.
Long Jiang Guang Han Gas Turbine Company has the capability of processing core components of 3-50MW industrial gas turbines, and has made breakthroughs in key core technologies such as pressurization, dual-fuel combustion, low emission, turbine blade cooling, coating application, vibration damping, and overall design, etc. These breakthroughs have enabled the company to independently develop and manufacture small and medium-sized gas turbines. These technological breakthroughs enable the company to independently develop new gas turbines, and continue to carry out the development, application and iterative upgrading of gas turbines of 5-50MW class.
GT25000 gas turbine, CGT25-D gas turbine is an industrial gas turbine independently researched and developed by 703 Institute, which is based on the mother model imported from abroad in the 1990s through independent research and development and a large number of design improvements, and has been completely localized and used in the industrial drive field. The rated power of this model reaches 26.7MW with an efficiency of 36.5%, and it can use diesel or natural gas as fuel, with mature technology, simple maintenance and good performance in variable working conditions. After years of development and improvement, GT25000 gas turbine has been completely localized and passed 72-hour assessment test at Novatek gas booster station in Russia, demonstrating its reliability under extremely low temperature environment.

GT25000
On January 12, 2023, the first localized unit of H-25 gas turbine, which was manufactured by Long Jiang Guanghan Gas Turbine Company on a trial basis, passed the full-speed full-load test and verification in the company's test bench, and all the indexes of function and performance meet the expected requirements, reaching the manufacturing level of the same type of unit imported from Japan.
In addition, Long Jiang Guanghan Gas Turbine Company also produces UGT6000, UGT15000, CGT25-E, H-25(32), CGT30, H-25(42), CGT40 and other models of gas turbines, which will not be listed for the limitation of space.
