摘要
阐述了随着空冷岛散热性能的日益老化,早期投产的直接空冷系统增容改造工作已提上日程安排。在对某600 MW机组直接空冷系统的设计特性及实际运行特性的变工况研究基础上,定量确定了不同环境温度下,主机及空冷系统性能不良对机组经济性的影响,研究结果对电厂直接空冷系统运行优化及系统改造工作具有重要的指导作用。
With the air-cooling island performance diminishing, direct air-cooling system that has gone into operation earlier need to be reformed and increase capacity. In this paper, based on the design characteristics and operation characteristics that is under off-design conditions of a 600 MW unit, the effects of＂ unit＇ s performance under different temperatures on the unit＇ s economic efficiency are identified, which gives guidance for the optimization of direct air-cooling system and system reformation.
