At 15:38 on August 21, Unit 3 ofUnit 3 of the Guoneng Chizhou project, equipped with a turbine-generator set supplied by HTC, successfully completed its 168-hour full-load reliability test run. The unit maintained stable operation across all systems throughout the test, marking the formal commercial operation of the first unit in the first thermal power project approved during Anhui Province's 14th Five-Year Plan period.

The Unit 3 turbine at the Guoneng Chizhou project is a 660MW-class, ultra-supercritical, double-reheat, single-shaft, five-cylinder, four-exhaust-flow, extraction condensing steam turbine supplied by HTC, equipped with 1040mm-class long last-stage blades, representing a significant breakthrough in energy efficiency. The unit incorporates HTC's latest technological achievements, including an optimized flow path to reduce energy loss, a redesigned valve configuration to enhance response performance, and an improved ultra-high-pressure steam admission structure to elevate thermal cycle efficiency. These synergistic innovations collectively ensure outstanding thermal performance and high flow path efficiency.
