摘要

为了减小滨海电厂温排水对取水以及周围环境的影响,采用非结构化网格,建立平面二维水动力模型,经率定和验证后对印尼西加里曼丹燃煤电厂不同取排水平面布置方案下的温排水扩散进行了数值模拟。研究结果表明,排水口位置及隔热堤长度、走向对温排水影响较大;应尽量增大取排水口之间的水平或垂向扩散距离;取排水布置还应考虑对周围海域生态环保的影响。文章根据研究结果与分析给出了取排水平面布置推荐方案,为取排水工程的设计提供了科学依据。
        In order to reduce the influence of thermal drainage on water intake and surrounding environment in coastal power plant, we built a two dimension hydrodynamic numerical model with unstructured grid. After calibration and verification, we simulated the diffusion of the thermal discharge under different plan layout of water intake and outfall system in West Kalimantan Coal-Fired Power Plant in Indonesia.The results show that the outfall location, the length and direction of heat insulation breakwater have a major influence on the thermal discharge. The vertical and horizontal diffusion distance between the intake and outfall should be increased as far as possible, the influence of the layout of water intake and outfall on the ecological and environmental protection of the surrounding sea areas should also be considered. According to the research results and analysis, we gave the recommended plan for the layout of water intake and outfall, which provides a scientific basic for the design of water intake and outfall works.
