The overall body type of the secondary reheat ultra supercritical 1000MW steam turbine product is single shaft, five cylinder four exhaust or six cylinder six 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 continues to innovate and upgrade 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. Currently, Shanghai Electric's market share of secondary reheating products exceeds 70%.
secondary reheat ultra supercritical 1000MW steam turbine covers a power range of 900MW to 1100MW, with steam inlet parameters ranging from 31MPa/600 ºC/610 ºC/610 ºC to 35MPa/610 ºC/630 ºC/630 ºC;
* 1000MW ultra supercritical steam turbines with secondary reheating was the world's first million level unit with secondary reheating;
As the largest supplier of steam turbine equipment in China, achieved the world's highest annual output in 2006. The secondary reheating ultra supercritical 1000MW steam turbine products have obvious advantages in thermal economy, safety and reliability, and convenient operation and maintenance, and the overall performance has reached the world-class advanced level.
Technical advantages:
The rated steam parameter range is from 31MPa/600 ºC/610 ºC/610 ºC to 35MPa/610 ºC/630 ºC/630 ºC. The steam distribution method adopts full cycle steam inlet and fixed slip operation. The ultra-high pressure cylinder and high pressure cylinder are jointly started, 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;
Can be configured with BEST small machines to further improve the economic efficiency of the unit;
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.
