Shanghai Electric’s Double reheat USC 660MW steam turbine covers the power range from 600MW to 700MW, and the steam inlet parameter range is from 31MPa/600℃/610℃/610℃ to 35MPa/610℃/630℃/630℃.
Up to March, 2019, there are 4 orders, 3 units in commercial operation.
Typical projects: Bengbu, Suqian.
Shanghai Electric’s USC steam turbine products have obvious advantages in heat economy, safety and reliability, as well as simple convenient operation and maintenance. The overall performance has reached the world first class level.
n High Performance
Small diameter, multi-series, high efficiency;
The optimized design of AIBT blade flow and CFD structure flow;
Measured heat rate≤ designed heat rate.
n Unique Structure
Higher main steam pressure, higher reheat temperature;
Rotors supported by N +1 bearings, 8-10 meters shorter than regular unit;
The dynamic and static parts are expanding in the same direction, and the sliding pin system is smoother;
All bearing seats are grounded, and back pressure changes have no effect on the shafting.
n Flexible Operation
Built-in stress/temperature control, one button start-up;
From 0 to rated speed within 5 min.
n Easy Maintenance
High reliability, overhaul interval: 12 years;
HP and IP module assembled in house and shipped as a whole;
Combined fuel tank, highly integrated auxiliary system.
