Product Description

Secondary reheat ultra supercritical 660MW steam turbine

The overall body type of the 660MW ultra supercritical steam turbine product with secondary reheating is a single shaft, five 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. Continuously innovating and upgrading products, creating multiple firsts, and leading the industry with its economic, safety, and flexibility advantages, it has received widespread praise and recognition from customers. Currently, the market share of secondary reheating products exceeds 70%.
The secondary reheating ultra supercritical 660MW steam turbine covers a power range of 600MW to 700MW, with steam inlet parameters of 31MPa/600 ºC/610 ºC/610 ºC 35MPa/610 ºC/630 ºC/630 ºC;


Technical advantages:
The rated steam parameters range 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+make-up valve, and operates in a fixed sliding fixed mode. The ultra-high pressure cylinder and high pressure cylinder are started together, with a rated speed of 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
