哈电汽轮机660兆瓦供汽机组在国能福州项目投运

Core Viewpoint - The successful commissioning of the 660 MW dual medium-pressure cylinder multi-level steam turbine unit by Harbin Electric Group marks a significant advancement in China's energy sector, showcasing innovative technology and meeting regional energy demands [1][3]. Group 1: Project Overview - The Guoneng Fuzhou Phase II project is a crucial part of Fujian Province's energy system, aimed at fulfilling regional electricity supply and industrial heating needs [3]. - The turbine unit developed is the first of its kind in the national energy sector, representing a major technological equipment demonstration project [1]. Group 2: Technological Innovations - The turbine features a breakthrough design that allows for efficient operation at 660 MW under pure condensation conditions while providing adjustable multi-level steam extraction capabilities [3]. - Three key technological innovations were achieved during the development: 1. The pioneering intercommunication technology between the supplementary steam valve area and ultra-high pressure heating [3]. 2. The application of a patented medium-pressure main steam regulating valve with fine-tuning capabilities [3]. 3. The adoption of a "dual medium-pressure cylinder" design to enhance the flexibility of low-pressure steam extraction regulation [3]. Group 3: Operational Impact - Once fully operational, the Guoneng Fuzhou Phase II project is expected to generate an annual electricity output of 12.6 billion kWh and provide multi-level industrial steam extraction [3]. - The successful application of this turbine model offers a new technical solution for centralized heating in industrial parks, with related technologies already being promoted in other projects such as Guoneng Qingshuiyuan and Guoyuan Power Hami [3].
