Steam turbine Supercritical 350MW

for power generation

Supercritical 350MW Steam Turbine To meet the diversified needs of different customers, the supercritical 350MW steam turbine has 11 types, including two-cylinder two-exhaust steam and three-cylinder two-exhaust steam turbines, which can adapt to water cooling or air cooling. Also industrial extraction or heating extraction can be provided. It has won several awards including the Gold Award of Shanghai Excellent Invention Selection Competition and the Third Prize of China Machinery Industry Science and Technology Award. Typical steam inlet parameters are 24.2MPa/566°C/566°C and 24.6MPa/569°C/569°C, and the rated back pressure ranges from 3.4kPa to 30kPa; By the time November 2019, we have got 89 orders, including 79 units of two cylinders and two exhausts, and 10 units of three cylinders and two exhausts. Typical projects include Shaoguan Yuehua, SIGC Linbei, Chinapower Shangqiu and Indonesian Qingshan. The latest products of this series mainly have the following features: 1.
