On December 31, 2022, the first domestically produced F-class 50-megawatt heavy-duty gas turbine known as the “fighting machine” was successfully ignited for the first time at the natural gas distributed energy station of Huadian Qingyuan Overseas Chinese Industrial Park. The successful ignition marks another step towards commercial operation of the F-class 50 MW heavy-duty gas turbine independently developed by Dongfang Electric Group, and China is about to open a new chapter in the high-quality development of independent gas turbines.

First pull the timeline back to November 25, 2022. In the gas turbine assembly workshop of Dongfang Steam Turbine, a subsidiary of Dongfang Electric Group, the first self-developed F-class 50-megawatt heavy-duty gas turbine in China was officially completed and shipped, and will soon enter the engineering application stage. It marks that my country has completed a breakthrough from “0” to “1” in the field of heavy-duty gas turbines.
Heavy-duty gas turbines are the core equipment in the field of power generation and drive, and are known as the “crown jewel” of the equipment manufacturing industry. They are a symbol of a country’s technological level and comprehensive national strength, and are also key equipment for developed countries to implement strict technological blockades. In order to serve the country’s major strategies, in 2009, Dongfang Electric Group gathered superior resources, established a scientific research team, and cooperated with nearly a hundred units in the upper, middle and lower reaches of the industrial chain to take the lead in developing F-class 50 MW heavy-duty gas turbines with completely independent intellectual property rights in China.

The 50MW heavy-duty gas turbine has gone through 13 years of independent research and development. From “0” to “1”, Dongfang Electric Group has mastered the key core technologies in its own hands, established a complete and reliable F-class gas turbine aerodynamic design, structural design and reliability evaluation system; , Turbine blade precision casting problems; built the first batch of component-level test platforms and complete machine test platforms for compressors, burners, turbines, and rotor dynamic balance in China; established a test verification system, and completed F-class 50 MW All verification tests for gas turbines. The official delivery of this heavy-duty gas turbine has opened up the “last mile” of the independent gas turbine from research to application, and will soon open a new chapter in the high-quality development of China’s independent gas turbine industry.
Gas turbines are extremely complex clean energy power generation equipment. Dongfang Electric Group’s F-class 50-megawatt heavy-duty gas turbine is composed of more than 20,000 parts. Its working pressure is 18 atmospheres, which is equivalent to the water pressure at a depth of 180 meters under the sea, and its working temperature exceeds 1300°C. Under such high temperature and high pressure conditions, it must rotate at a high speed of 6000 rpm, and the linear speed is more than twice the flight speed of a large passenger aircraft.

Compared with thermal power generation units of the same power, Dongfang Electric Group’s F-class 50-megawatt heavy-duty gas turbine can reduce carbon emissions by more than 500,000 tons a year, and the combined cycle power generation exceeds 70,000 kWh per hour, which can satisfy 7,000 households for a day The demand for electricity will actively promote the realization of the “double carbon” goal.
The F-class 50-megawatt heavy-duty gas turbine development project has united universities, scientific research institutes, and nearly 300 enterprises in the upper, middle and lower reaches of the industrial chain to work together to create a safe, controllable, independent and reliable gas turbine industrial chain, and achieve a 100% localization rate of the main engine.
The project also cultivated a high-quality gas turbine research and development talent team. The team has successively won honorary titles such as the Outstanding Scientific and Technological Innovation Team of Central Enterprises and the Youth Civilization of Central Enterprises. It has accumulatively obtained 136 authorized invention patents, published more than 300 papers, published 2 monographs on gas turbines, and participated in the formulation of 6 national/industry standards. More than 1,000 enterprise standards.
Dongfang Electric Group will shoulder the heavy responsibility of a big country, strive to create a source of original technology and a long chain of modern industrial chains, and make greater contributions to helping achieve high-level technological self-reliance and building a national strategic technological force, in the vast journey of “Chinese-style modernization” Show more “Oriental deeds” in the film.
After 13 years of independent research and development, the first domestically produced F-class 50-megawatt heavy-duty gas turbine, known as the “fighting machine”, achieved its first successful ignition on December 31, 2022 at the natural gas distributed energy station of Huadian Qingyuan Overseas Chinese Industrial Park.

Heavy-duty gas turbines are the core equipment in the field of power generation and drive, reflecting the overall capacity of a country’s heavy industry. In May 2022, the National Energy Administration officially announced that the G50 heavy-duty gas turbine (50 MW) developed by Dongfang Electric Group will enter the list of the first (set) major technical equipment projects in the energy field in 2021. The whole machine has more than 20,000 parts, and the working pressure is 18 atmospheres, which is equal to the water pressure at a depth of 180 meters under the sea; the working temperature exceeds 1,300 degrees Celsius, and it rotates at a high speed of 6,000 rpm.
This F-class 50-megawatt heavy-duty gas turbine is initially expected to be officially connected to the grid for power generation in early January 2023. Compared with thermal power generation units of the same power, it can reduce carbon emissions by more than 500,000 tons a year, and the combined cycle can generate more than 70,000 tons of electricity per hour. Kilowatt hours can meet the electricity needs of 7,000 households for one day. GS Approved Manufacturer of conventional edm
