The development of heavy-duty gas turbines in China started relatively late, and it was not until the end of the 90s of the 20th century that it began to be truly invested in research and development, and there is a large gap compared with the developed countries in the West. However, through technical cooperation with countries such as Italy, Japan and Ukraine, we have gradually achieved a major breakthrough in this field.
The world's first echelon: the United States, Germany, Japan, occupy more than 80% of the world's market. United Kingdom (military under 100 MW).
Second echelon: Italy, France.
Third echelon: China, South Korea, Ukraine, Russia.
1. Introduce Ukrainian technology - lay the foundation.
Localization - UGT2500 gas turbine.
In 1990, China introduced Ukraine's UGT25000 gas turbine (Wugoutou), digested and absorbed the development of GT25000 and QC-280 QD-280 gas turbines with independent intellectual property rights, which solved the problem of insufficient power of military ships.

AGT-110 heavy-duty gas turbine.
The AGT-110, the most powerful gas turbine independently developed in China, is a Class E standard, with a power of up to 100 MW and a thermal efficiency of 415% advanced equipment. The gas turbine was developed by Aero Engine Corporation of China and rolled off the assembly line in 2023. Its technology ** is a semi-finished product of the Soviet heavy gas turbine GTD-110. After the collapse of the Soviet Union, China imported all the modified gas turbine technology from Ukraine, and carried out in-depth development on this basis, and finally successfully developed the AGT-110 gas turbine with better performance. In contrast, Russia developed the GTD-110M model on the basis of the GTD-110, which reached 130 megawatts, but could only achieve 375% thermal efficiency. At present, due to the immaturity of technology, it does not have the ability to be commercially applied. The AGT-110 is better than the blue, outperforming the Russian GTD-110M gas turbine.

Second, the introduction of Italian technology - milestone significance.
The GT36-S5, China's most powerful gas turbine, is a state-of-the-art facility with a powerful output of 538 MW and a combined cycle power generation efficiency of up to 62%. This gas turbine is the result of the development and refinement of the GT36-S6 gas turbine from Ansaldo in Italy. The production and manufacturing of this type of gas turbine was completed in Shanghai and successfully rolled off the production line in 2023. It is worth noting that China acquired a 40% stake in Ansaldo in 2014 and established a joint venture with it in Shanghai, but the core technology is still in the hands of Italian companies. The GT36-S5 gas turbine can be regarded as a product of Sino-Italian joint research and development.

3. Introducing Japanese technology - making a leap forward.
In 2019, China Shipbuilding Industry Corporation introduced the H-25 gas turbine, which has an output power of 30 MW, a single-cycle power generation efficiency of about 38%, and a comprehensive thermal efficiency of up to 84% in the combined heat and power mode, which is used in cogeneration, distributed energy systems and marine power. Through digestion and absorption, China has not only improved its own design and manufacturing capabilities, but also gained the opportunity to enter the international market.

Localized - Mitsubishi M701J heavy-duty gas turbine.
China's Dongfang Electric Co., Ltd. purchased Japan's Mitsubishi's advanced heavy-duty gas turbine technology, the M701J, and localized it in October 2022. At the Dongfang Steam Turbine Plant in Deyang City, Sichuan Province, the first domestic M701J heavy-duty gas turbine was successfully assembled and officially rolled off the production line. M701J gas turbine is an efficient and environmentally friendly gas turbine manufactured by Mitsubishi Heavy Industries of Japan, with the world's leading technical level. The gas turbine uses an advanced combustion chamber design and high-temperature materials to achieve a combination of high efficiency and low emissions. Its simple cycle power reaches 470 MW and combined cycle power reaches 680 MW, which has the characteristics of high efficiency, low consumption and low emission.

China's heavy-duty gas turbine technology can make such great progress in a short period of time, which is inseparable from the technology transfer and support of Italy, Japan and Ukraine, and China's heavy-duty industrial gas turbine has ranked among the third echelon in the world.
