世界各大公司表面式凝汽器的主要结构特点比较

Overview on Main Structure Characteristics of Surface Condensers in the World

随着电站机组单机容量、热力参数的提高,对作为主要辅机的凝汽器提出了更高要求。即使同一等级的凝汽设备.世界各电站设备制造公司的凝汽器结构也各不相同.形成了各种风格和流派。文章列举了世界上具有代表性的FOSTER WHEELER、TEI、TOSHIBA、ALSTHOM、ABB、SIEMENS公司的凝汽器结构特点,针对凝汽器的管束、空冷区、管束倾斜、连接形式等主要结构。进行了分析与比较。为了解凝汽器的现状,把握其发展趋势提供参考。

As a single power station unit increases in its capacity and thermal parameters, much higher requirements are to be expected on a condenser-the major auxiliary equipment of a power station. Although condensers, made by different manufacturers in the world, are in the same capacity, they are different from each other in structures, and therefore, different in styles and forms. This article describes the structures and characteristics of different condensers made by leading companies in the world, thus consisting of FOSTER WHEELER, TEl, TOSHIBA, ALSTHOM, ABB and SIEMENS, through analyzing and comparing the main structures of different condensers, including tube bundle, air cooling zoon, inclination of tube bundle and connection form of condensers, so as to provide the readers for reference in the field of condensers＇ present status and developing tendency.
