1000MW Ultra Supercritical Steam Turbine

1000MW Ultra Supercritical Steam Turbine is divided into the following categories: ultra supercritical, intermediate reheating, single axis, four-cylinder four-exhaust, pure condensation, and extraction condensation. Main steam pressure is 25 ~ 28MPa. Main steam temperature is 600 ℃ and reheat steam temperature is 600/610/620 ℃.

  • The unit is supported by single bearing and its total length is only 28 meters.
  • It has advanced flow and blade design which ensure a high flow efficiency.
  • It holds more than 60% share of the market of 1000MW thermal power generators. A great deal of results confirmed that its various performance indicators reach or surpass design specifications and it reaches the world leading level.
  • High or middle pressure cylinder can be shipped to the site as a whole which can ensure high reliability and it needs overhaul after twelve years.
  • It has a unique expansion system and high shaft stability. In addition, it can achieve a key to start or to stop.

For ultra-low back pressure unit, there are five-cylinder six-exhaust models for selection.
