Product Description

ultra supercritical 660MW steam turbine


The overall body type of ultra supercritical 660MW steam turbine products is single shaft, four cylinder four exhaust or three cylinder four exhaust structure, which can adapt to different cooling methods such as wet cooling or air cooling, and can provide large capacity extraction to meet heating or industrial needs. Shanghai Electric continuously innovates and upgrades its products, creating multiple firsts. With its economic, safety, and flexibility advantages, it is far ahead in the industry and has received widespread praise and recognition from customers.
The ultra supercritical 660MW steam turbine covers a power range of 600MW to 700MW, with steam inlet parameters ranging from 25MPa/600 ºC/600 ºC to 30MPa/610 ºC/630 ºC;
The rated steam parameters range from 25MPa/600 ºC/600 ºC to 30MPa/610 ºC/630 ºC. The steam distribution method adopts full cycle steam inlet+make-up valve, and operates in a fixed sliding fixed mode. The high and medium pressure are started together, and the rated speed is 3000r/min. The main technical advantages are as follows:
1) Efficient performance:
Small diameter, multiple stages, high efficiency;
Optimization design of AIBT blade flow and CFD structure flow;
Multiple units' measured heat consumption ≤ design heat consumption;
2) Unique structure:
The cylindrical high-pressure cylinder can withstand higher main steam pressure/temperature;
N+1 bearing support, short shaft system;
A smooth sliding pin system with moving and stationary components expanding in the same direction;
3) Flexible operation:
Built in stress/temperature control, one click start;
It takes 5 minutes to reach the rated speed from 0 speed;
4) Easy maintenance:
The unit has high reliability and undergoes a major overhaul every 12 years;
Assembly and overall shipment of high and medium pressure cylinders in the factory;
Combination fuel tank, integration of auxiliary systems.
