一座发电厂“点亮”半座城 重装之都为自己“充电”

Core Viewpoint - The article highlights the advancements in energy infrastructure in Deyang, particularly through the development of a significant gas-fired power generation project, which aligns with China's 14th and 15th Five-Year Plans for optimizing energy supply and promoting clean energy technologies [3][4]. Group 1: Project Overview - The M701J gas turbine, developed by Dongfang Electric Group, is operational at the Sichuan Energy Investment Zhongjiang Gas Power Plant, marking it as the largest single gas power project in the province [3]. - The first unit of the project has completed a full-load test run and is expected to generate 3.5 billion kilowatt-hours annually, equivalent to half of Deyang's electricity consumption for six months [4][5]. - The project employs a combined cycle technology with an efficiency of 63.58%, significantly reducing coal consumption by over 350,000 tons annually compared to similar coal-fired units [4]. Group 2: Regional Impact - The project not only serves Deyang but also supports the energy needs of Chengdu, enhancing the regional energy supply structure and contributing to high-quality economic development [5]. - Deyang is a critical manufacturing hub for power generation equipment, producing a significant portion of China's gas and nuclear power units, which positions it well to meet the increasing electricity demand driven by rapid industrialization [4]. Group 3: Technological Advancements - The project has achieved a new record in rotor dynamic balance precision for gas turbines, with a rated speed of 3000 RPM and vibration control at the micrometer level, ensuring longevity and safety [5]. - The local collaboration in manufacturing and assembly has led to a unique "zero counterweight" operation for the gas turbine, showcasing the efficiency of local production capabilities [5].
