Core Viewpoint - The company, Guoneng (Lianjiang) Port Power Co., Ltd., is pioneering noise reduction technologies in the thermal power industry, aligning with China's "dual carbon" strategy to achieve sustainable development while maintaining high operational efficiency [2][12]. Group 1: Project Overview - Guoneng Lianjiang Company operates a power plant with an annual generation capacity exceeding 100 billion kilowatt-hours, implementing innovative noise control measures to redefine ecological boundaries in the thermal power sector [2]. - The company has initiated an environmental noise reduction project that integrates advanced technologies to address the challenges of noise pollution from power generation processes [4][5]. Group 2: Technical Innovations - The project employs a multi-physical field collaborative optimization approach, addressing noise issues through innovative solutions such as vibration suppression and noise reduction technologies [8][9]. - The company has developed a "structural decoupling" vibration control scheme, achieving over 95% vibration isolation efficiency and a sound insulation level exceeding 35 decibels [9]. - The use of aerospace-grade aerogel materials in the insulation of major pipelines has resulted in significant improvements in both sound insulation and thermal conductivity, achieving a sound transmission class (STC) of 45 and a thermal conductivity of ≤0.023 W/(m·K) [10]. Group 3: Project Management and Execution - The project commenced in August 2024 and faced challenges such as adverse weather conditions and complex construction environments, necessitating a robust management framework that integrates safety, quality, and progress control [15][17]. - A comprehensive quality management system was established, ensuring that all acoustic materials were rigorously tested and monitored throughout the construction process, achieving a 100% pass rate at key quality control points [16]. Group 4: Environmental Impact and Recognition - The noise reduction project has successfully lowered noise levels at various sensitive points, with reductions exceeding 15 dB(A) in critical areas, surpassing national standards [17]. - The project has been recognized for its innovative contributions to noise control in the power industry, with two core technology patents accepted by the National Intellectual Property Administration [12].
