直接空冷机组冬季防冻试验研究

摘要

Taking a typical 300 MW direct air cooling unit triangle radiator as experimental object, the air temperature and air speed variation of the triangle radiator for direct air cooling unit were tested with natural air flow, which provides reference for determining reasonable operating mode for anti-freezing.%以某典型300 MW直接空冷机组的三角单元散热器为试验对象,测试了直接空冷机组在自然抽吸、风机停运、关闭蒸汽分配管蝶阀以及风机入口加装堵风装置后的散热器风温、风速变化规律,为确定合理的防冻运行方式提供依据.
