直接空冷凝汽器的设计与施工

Design and Construction of Direct Air-cooled Condenser

国电电力大同第二发电厂二期扩建工程引进的2×600 MW直接空冷凝汽器系统采用铝钢单排管变频调速风机直接空冷凝汽器。其设计和安装工艺均有许多与以往水冷凝汽器不同之处。安装机械的布置、各部件和管道的组装、安装顺序和方法对最后的质量均起重要的作用。同时要重视安装过程中需要注意的事项。

The imported 2×600 MW unit air - cooled condense system introduced in Datong No.2 power plant expansion project uses direct aircooled condenser with single - row aluminum - steel tubes and frequency - converted adjustable - speed fans. The design and installation techniques are different from that of traditional water - cooled condensers. The machine arrangements, parts and pipelines assembly, and installation procedures have crucial affects on final quality. At mean time, matters that need attention during the installation should not be ignored.
