Shaoguan&32;Yuehua&32;2X350MW&32;Supercritical&32;CFB&32;Project
The Shaoguan Yuehua power plant has built 2X350MW supercritical CFB power generation units. The steam turbine is the newly developed by SEPG. The two units passed the 168 hours operation on July 20, 2017 and November 10, 2017. This project is the first time that SEPG has applied internal HIP inner cylinder, steam turbine one-click start and stop technology, single bearing support technology, and split steam valves to supercritical 350MW class units.

    • The performance test shows the measured heat consumption is better than the guarantee;

    • High degree of automation, one-click start and stop;

    • The HIP module is overall shipped after assembly.


In addition to its obvious advantages in thermal economy, safety, reliability and ease of operation and maintenance, this series of products also adopt the overall shipment of HIP module, greatly shortening the installation time and improving the installation accuracy. At the same time, the application of AIBT technology, “one click start and stop”, thermal stress control and other unique technologies have improved the overall performance of the unit.

1. Efficient performance

1) small diameter, multi-stages, high efficiency;

2) AIBT based blade flow and structure optimization design by CFD;


2. Unique structure

1) Integrated HIP inner casing;

2) Split main steam valve and integrated reheat valve;

3) Bearing pedestals floor arrangement, single bearing support, smooth sliding system;

4) Integrated lube oil module, high integration of auxiliary system.


3. Flexible operation

1) Built-in thermal stress control, one-button start;

2) The integrated design of the stators leads to easier maintenance;

3) High reliability;

4) The overall shipped after assembly of the HIP;
