Xinneng，Yumen：solar-thermal&32;50MW
Yumen xinneng photothermal first power co., LTD. Molten salt tower type 50mw photothermal power generation project was selected into the first batch of photothermal power generation demonstration projects in September 2016.This project adopts the tower secondary reflection concentrated light power generation technology, and the annual utilization rate of the generator set is about 4328 hours.

    • Rate power：50MW（max54MW）

    • Steam inlet ：14MPa/540℃/540℃

    • Rate flow：150.4t/h（Max：164.2t/h）

    • Regeneration system：7

    • Back pressure：8.0kPa(a）

    • Rotating speed : 6300 r/min


The energy source of photothermal turbine is unstable solar radiation,steam turbine unit needs to start quickly and frequently, which requires high reliability of the unit,the technical department in the program design stage carried on the demonstration of multiple programs and the life analysis of different operating states.The steam turbine unit will also adopt the self-start and stop technology with life evaluation, which can reduce the difficulty of the users and realize the automatic start, stop and load adjustment according to the state of the unit.

1）Safety and reliability

We are, and will always be making safety and reliability put first. With the experience of the continuously accumulated operation data from more than 2,000 units, we can ensure the safety and reliability of new designed units throughout the lifecycle and the units can continuously run for over five years.

2）High efficiency

The top performance record is continuously refreshed by our start-of-art technology of AIBT full-automatic flow path design system and CFD technology.

3）Easy installation

For maximum easy installation, we can provide integral transportation.

4）Operation flexible

We always focus on making operation more flexible. Through online real-time analysis of the thermal stress, full-automatic control of unit during startup, normal operation, load change and shutdown can be realized.

5）Maintenance convenience

We are dedicated to make maintenance much simpler, only twice overhauls throughout the 30-year service life, increasing at least 4,000 operating hours.
