精选优质文档-倾情为你奉上600MW直接空冷凝汽器管束冻结因素与防冻措施摘要:空冷凝汽器冬季运行中,凝汽器翅片管内饱和蒸汽热负荷与翅片管冷却能力不平衡是导致直接空冷凝汽器管束发生冻结的主要因素,而不凝结气体在内部聚积则加剧了冻结的发生。防止空冷凝汽器的冻结的措施有:设计上采用顺逆流结构等;运行上控制蒸汽流量和冷空气流量以及不凝结气体的抽出等关键词:空冷凝汽器 冻结因素 防冻措施600MW direct air-cooled condenser tube bundle of freezing factors and anti freezing measuresLiuzhenshengNingxia Datang International Daba Power Generation Co., Ltd.,NingXia Qingtongxia Abstract: The condenser operation in winter, condenser fin tube saturated steam heat load and the cooling
