Supercritical 350MW steam turbine

supercritical 350MW class steam turbine

The steam turbine serves as the core energy conversion equipment in thermal power plants. Its main structure consists of a stator and rotor, with steam seals installed between them. The stator is supported by a base plate and sliding pin system. To regulate steam intake, a steam distribution mechanism is installed. For safety assurance, a turning device is also equipped.

To cater to diverse user requirements, our 350MW supercritical steam turbine series offers multiple configurations. These include two-cylinder, two-stage steam turbines with high/medium-pressure combined cylinders, and three-cylinder, two-stage steam turbines with split-cylinder designs. The turbines are compatible with both wet and air cooling systems, and can provide industrial extraction steam as well as heating extraction steam.

The typical steam inlet parameters are 24.2MPa/566℃/566℃ and 24.6MPa/569℃/569℃, and the rated back pressure ranges from 3.4kPa to 30kPa.
