The first domestic F-class 50MW heavy-duty gas turbine independently developed by Dongfang Electric Group successfully realized full load stable operation. On November 27, academicians of the Chinese Academy of engineering Chenxuedong, the leader of the expert group to witness the full load operation of 50MW heavy-duty gas turbine, officially announced: "Dongfang Electric independently developed the first domestic class F 50MW heavy-duty gas turbine, which has reached full load, all operating indicators are normal, and the expert group has witnessed it." Thunderous applause broke out at the scene. The first domestic class F 50MW heavy-duty gas turbine independently developed by Dongfang Electric Group successfully realized full load and stable operation. Six academicians, including yeqizhen, guguobiao, wenxueyou, guoliejin, chenxuedong and hanjiecai, as well as 10 specially invited experts, Ligang, vice governor of Sichuan Province, leaders of the Ministry of industry and information technology, the energy administration and the state owned assets supervision and Administration Commission of the State Council, as well as relevant leaders of some local governments, associations, universities, institutes and enterprises, witnessed this historic moment

Ligang, vice governor of Sichuan Province, said that the full load operation of the first F-class 50MW heavy-duty gas turbine in China is a major milestone in the development history of Dongfang Electric Group and a major achievement in the high-quality development of Sichuan's economy. In particular, it has made outstanding contributions to the national breakthrough in the key core technology of heavy-duty gas turbines. The Party Central Committee and the State Council attach great importance to scientific and technological innovation. The Fifth Plenary Session of the 19th Central Committee of the Communist Party of China put forward to take innovation as the core work in the overall historical process of China's modernization, and take scientific and technological self-reliance and self-improvement as the strategic support for the development of national modernization. As an important national central enterprise, Dongfang Electric Group must seize the historical opportunity, actively serve the national strategy, actively connect with the "fourteenth five year plan" and the medium and long-term plan, make new and greater contributions to promoting the low-carbon development and counter trend development of the energy industry, and promote the high-quality development of Sichuan economy

Zou Lei, Secretary of the party leading group and chairman of Dongfang Electric Group, said that in 2009, Dongfang Electric Group was determined to achieve a major breakthrough in independent gas turbines from "None" to "yes", and embarked on the road of independent research and development of 50MW heavy-duty gas turbines to overcome the reading error of human eyes. "Sharpening a sword in ten years" has been completed after many setbacks and heavy weapons. He pointed out that the Fifth Plenary Session of the 19th Central Committee of the Communist Party of China clearly put forward that we should adhere to the core position of innovation in the overall situation of China's modernization, and take self-reliance and self-improvement in science and technology as the support of the national development strategy. Facing the accelerated evolution of a new round of global scientific and technological revolution and industrial reform, and the accelerated formation of a new development pattern of "double cycle" at home and abroad, Dongfang Electric Group will continue to take innovation as the first driving force, build "a big country and a heavy weapon", promote the high-quality development of enterprises, and contribute to the prosperity of the country and the rejuvenation of the nation

the witness ceremony was presided over by Huang Wei, deputy secretary of the party leading group and director of Dongfang Electric Group

gas turbine is a strategic equipment involving energy field and national defense construction, and is known as the "pearl on the crown" of manufacturing industry. High temperature components of gas turbine operate above the melting point of metal for a long time. At the same time, high temperature components bear extremely high stress and corrosive environment, so it is very difficult to design. For decades, the technology of design, manufacturing and test verification of high-temperature gas turbine components is still blank in China, which greatly hinders the establishment and development of China's independent gas turbine industry system

as one of the important state-owned backbone enterprises involved in national security and the lifeline of the national economy, Dongfang Electric Group has always taken independent innovation and serving the country through industry as its own responsibility, actively connected with major national strategic needs, took the lead in developing F-class 50MW heavy gas turbine with completely independent intellectual property rights in China, opened an ice breaking journey, and vowed to win this "pearl on the crown". Since 2009, when modified plastics have outstanding heat resistance, Dongfang Electric Group has made every effort to pool advantageous resources, set up Dongfang turbine G50 development center, set up a scientific research team of more than 100 people, and successively invested nearly 2billion yuan to promote research and development. At the same time, as the first of the group's major scientific and technological projects, the group has formulated special research programs and incentive programs to vigorously promote the implementation, aiming to make every effort to break through technical barriers, drive the coordinated development of upstream and downstream gas turbine industry chains, and fill the gap in China's gas turbine industry system

after ten years of sharpening a sword, Dongfang Electric Group has independently researched and developed the first domestic F-class 50MW heavy-duty gas turbine to break through many difficulties. It has successively completed the overall and component structure design of the gas turbine, built the first domestic high-pressure ratio and large flow compressor test bench, the first domestic F-class burner test bench, multiple turbine component test benches and the domestic maximum power machine test platform, overcome the difficulties in manufacturing high-temperature turbine blade blanks, and established a professional Excellent R & D team. On september27,2019, the initial battle of independent research and development was won, and the ignition test of the first domestic class F 50MW heavy-duty gas turbine was successful

2020, Dongfang Electric Group will accelerate the research and development process of gas turbines. On May 12, the single station power supply must have a good "grounding" device, and the two stations, three stations and four stations are displayed respectively; Synchronous rapid experiment; Automatic reset; Automatic judgment of qualified and unqualified; Multi window display of experimental data; Temperature control display; The alarm prompt officially started the on load test at the design speed, reaching 25% load on June 22, 50% load on August 10, and 75% load on September 9. On September 22, the gas turbine finally operated to 100% load for the first time, making a major breakthrough in the test. On November 27, witnessed by academician experts, government leaders and customer representatives, the gas turbine successfully realized full load and stable operation

full load test is the most critical verification node in the research and development of gas turbine, and it is also the last performance test before long-term operation of the power station. The complete success of this full load test indicates that Dongfang Electric Group has completely mastered the whole process of gas turbine independent design, manufacturing and test, and promoted the leap forward of China's independent gas turbine industry
