让百万市民温暖过冬！张掖电厂实现“双投产”

Core Viewpoint - The Gansu Electric Power Zhangye Power Plant's expansion project has successfully completed a 168-hour full-load trial operation, marking the shortest interval for commissioning similar units in China, with both units achieving efficient production within a month [1][7]. Group 1: Project Overview - The project is located in the Zhangye Economic and Technological Development Zone and is a key part of the Hexi Corridor clean energy base, featuring the construction of two 1000 MW ultra-supercritical indirect air-cooled coal-fired units [3][9]. - The project includes the installation of flue gas desulfurization, denitrification, and dust removal facilities alongside the new units [3][9]. Group 2: Innovative Technology Integration - The project employs advanced technologies such as high-capacity, high-parameter, and high-efficiency equipment, achieving a power consumption of 281 grams per kilowatt-hour and a plant utilization rate of only 4.2%, which are internationally leading indicators [4][9]. - Innovations like "semi-capacity steam-driven feedwater pumps" and "air preheater bypass heat recovery" enhance the units' deep peak regulation capability by 19% THA, providing critical support for renewable energy consumption [4][9]. Group 3: Resource Recycling and Environmental Impact - The project features the first all-steel structure indirect cooling tower in the Hexi region, which shortens construction time and simplifies the process, with a height of 190 meters and a cooling area of 2.67 million square meters [5][11]. - It implements a full-process wastewater treatment system and indirect cooling technology, achieving zero external discharge of wastewater and rainwater, and zero fuel consumption, representing a new direction for clean and low-carbon coal power [5][11]. Group 4: Enhancing Peak Regulation Capacity - The commissioning of the two units will significantly enhance the capacity of the Hexi power grid and improve peak regulation capabilities, ensuring stable electricity supply during the 14th Five-Year Plan period in Gansu [6][12]. - The project will provide reliable peak regulation and compensation for the abundant wind and solar energy resources in the Hexi region, promoting local renewable energy consumption and contributing to Gansu's green and low-carbon transition [6][12]. Group 5: Societal Benefits - The project will provide stable heating sources for 18 million square meters of urban residential areas, enabling the first "dual heating source" supply in Zhangye, benefiting millions of residents during winter [10][14].
