【摘要】 <正> 蒸汽循环发电系统的主要特征是不断排放大量低品位热能。缺水矿口电力生产的限制性条件是电站冷却大量用水。直接空冷系统(GEA系统)不适应机组向大容量的发展,水循环间接空冷系统(Heller系统)其热效率较低。本文以1000MW电站为参考,研究间接空冷系统,旨在寻求一种节能省水、经济效益显著的电站空冷系统方案设计。更多还原

【Abstract】 This paper concerns with design of indirect dry-cooling systems in power plants. The effects of different cooling mediums, terminal and initial temperature differences, and heat exchanger materials on performances of dry-cooling systems have been analyzed. Three different indirect dry cooling systems haven been compared with each other. Ammonia phase-change system is a adavanced dry-cooling system.更多还原
