Recently, the 2×660MW ultra-supercritical units of the Chuzhou Power Plant under Zhongmei Xinji Energy Co., Ltd. successfully completed their 168-hour continuous full-load trial operation, officially meeting the conditions for commercial operation. As the supplier of the condensate polishing system equipment for the project, Shanghai Hysunny Hi-Tech Materials Co., Ltd. (hereinafter referred to as "Shanghai Hysunny") has completed the manufacturing and delivery of all equipment. The supplied equipment was commissioned in sync with the units and has been operating stably, providing solid equipment support for the deep purification of condensate and the long-term reliable operation of the system.
The condensate polishing system equipment delivered this time covers the process units of pre-filtration, high-speed mixed beds, resin external regeneration and auxiliary supporting systems, serving the entire process flow of precision condensate filtration, deep demineralization and resin activation and regeneration. During unit operation, the condensate from the condensate pumps first passes through the pre-filters to remove suspended solids and impurities, and then enters the high-speed mixed beds, where deep demineralization is achieved through cation and anion resins, producing high-quality polished water that is fed into the boiler thermal system. When the resins become saturated, the system automatically switches to the regeneration process: the sulfuric acid storage tank and the caustic soda storage tank supply regeneration reagents steadily, the demineralized water tank for regeneration ensures a continuous supply of rinsing water, and the compressed air storage tank provides a stable air source for resin scrubbing and pneumatic valve control, jointly completing the activation and regeneration, displacement rinsing and performance recovery of the resins. The complete system equipment matches the full operating conditions of the units, with every link — from online purification to offline regeneration, from water quality monitoring to reagent regulation — working in efficient coordination, ensuring the stable, continuous and efficient operation of the condensate polishing system.
Project Overview
Located in Banqiao Town Industrial Park, Fengyang County, Chuzhou City, Anhui Province, the Zhongmei Xinji Chuzhou Power Plant is a key power construction project for power supply assurance, support and peak-shaving during Anhui Province's "14th Five-Year Plan" period. Phase I of the project comprises two 660MW ultra-supercritical double-reheat coal-fired generating units, with full-chain environmental protection and auxiliary systems — including flue gas desulfurization, denitrification and condensate polishing — constructed in parallel. Adopting advanced clean power generation technologies, the plant's environmental indicators meet ultra-clean emission standards, achieving zero wastewater discharge across the entire plant.
As the core auxiliary system safeguarding the quality of the units' water-steam cycle, the condensate polishing system is implemented by Datang Environmental Industry Group Co., Ltd., with Shanghai Hysunny providing the complete set of core equipment for the project. The system directly undertakes deep condensate purification, impurity removal and water quality regulation, effectively preventing and controlling the risks of corrosion and scaling in core equipment such as the boiler and steam turbine — which is crucial to extending the service life of the units and reducing operation and maintenance costs.
Following the full commissioning of the Zhongmei Xinji Chuzhou Power Plant project, it will further strengthen the power supply guarantee capacity of the Yangtze River Delta region and provide stable energy support for the high-quality development of local industry. In the future, Shanghai Hysunny will continue to deepen its presence in the power and energy industry, delivering integrated solutions that combine intelligent equipment manufacturing with deep technology integration across fields such as chemical water treatment and power transmission and distribution, laying a solid equipment foundation for the high-quality development of the energy industry and injecting sustained momentum into the green and low-carbon transformation of the power industry.
