Achieve zero breakthrough! The first domestic shipment

On November 25th,China’s first self-developed F-class 50 MW heavy-duty gas turbine was officially completed and shipped in Deyang, Sichuan. It is about to enter the stage of engineering application,It marks that my country has completed a breakthrough from “0” to “1” in the field of heavy-duty gas turbines.

< span>The heavy-duty gas turbine known as the “Pearl in the Crown” of the equipment manufacturing industry,is the core equipment in the field of power generation and drive,Reflects a country’s technological level and comprehensive national strength.

2009, East The Electric Group established a scientific research team, united nearly a hundred units in the upper, middle and lower reaches of the industrial chain, and took the lead in the development of F-class 50 MW heavy-duty gas turbines with completely independent intellectual property rights in China. After 13 years, it finally opened up the path from research to application of independent gas turbines. “The last mile”.

“Gas turbines are extremely complex clean energy power generation equipment, and Dongfang Electric’s F-class 50M The whole watt heavy-duty gas turbine is composed of more than 20,000 parts.” The relevant person in charge of Dongfang Electric Group introduced that the working pressure of the heavy-duty gas turbine is 18 atmospheres, which is equivalent to the water pressure at a depth of 180 meters on the seabed, and the working temperature exceeds 1300 ℃. 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 to the same Can reduce carbon emissions by more than 500,000 tons a year, Combined cycle one The hourly power generation exceeds 70,000 kWh, which can meet the electricity demand of 7,000 households for one day.
