Dongying，Datang：2X1000MW&32;project&32;full&32;capacity&32;feed&32;water&32;pump&32;turbine
Datang dongying project is the first six-cylinder, six-row steam eleven level regenerative unit with one million units in China.It consists of a single-flow ultra-high pressure cylinder, a double-flow high-pressure cylinder, a double-flow medium pressure cylinder, and three 12.5m2 double-flow low-pressure cylinders arranged in series.

    • Rate power：32MW（Max：41MW）

    • Steam inlet ：0.9～1.6MPa(a)/ 350～400 ℃

    • Rate flow：126t/h（Max：153t/h）

    • Back pressure：～6.79kPa(a)

    • Rotating speed : 2800～500r/min


The turbo unit adopts the advanced AIBT integrated flow technology to reduce energy consumption, and improves the circulating thermal efficiency of the whole unit by increasing the heat recovery series and adopting ultra-low back pressure.Based on the design of ultra-supercritical secondary reheat series units, this unit is the most numerous cylinder and the longest shafting in our factory.


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.
