DEC Completes China's First Self-developed F-class 50 MW Heavy-duty Gas Turbine

is about 50,000 square meters, which is about the size of 7 standard football fields. The wheel hub is 146 meters high, equivalent to the height of a 50-story building. This wind turbine has the largest single capacity, the largest impeller diameter and the lightest weight per megawatt in the world. It marks an important breakthrough in the high-end equipment manufacturing capacity of Chinese offshore wind power large-capacity units, reaching the international leading level. It is jointly developed by the Three Gorges Corporation and Goldwind Technology, which is the vice president member unit of China Foundry Association.

The 16 MW offshore wind turbine has achieved important technological breakthroughs, such as large spindle bearings and ultra-long lightweight blades. The digital level for its monitoring of the operation condition is high, which can adjust the operation mode intelligently in dealing with the typhoon and other bad weather, ensuring the safety and efficient power generation.

The 16 MW offshore wind turbine can generate 34.2 KWH for each rotation of a single unit with rated working conditions, and an average of more than 66 million KWH of clean electric energy can be produced annually, which can meet the annual electricity need of 36,000 three-people households, and about 22,000 tons of standard coal can be saved and about 54,000 tons of carbon dioxide can be reduced. ■

On November 25th, DEC completed China's first selfdeveloped F-class 50 MW heavyduty gas turbine, which was ready for delivery in Deyang, Southwest China's Sichuan province, indicating a scientific and technological breakthrough in the heavy gas turbine field in China.

The turbine can reduce carbon emissions by over 500,000 tons a year. It will produce more than 70 MWh of electricity per hour in a combined cycle power generation system, meeting the demand of 7,000 households for a whole day. ■
