中文摘要:
      直接空冷机组具有明显的节水效果,但也存在诸如汽轮机的运行背压高且变幅大、直接空冷凝汽器的冷却性能受环境、风和砂尘的影响大、直接空冷凝汽器冬季运行时容易发生冻结、凝结水溶氧超标以及热污染等运行方面的问题,针对这些现象及原因进行了分析,并提出对策。
英文摘要:
      The use of direct air-cooled condenser units can save water significantly, but there exist some problems in operation, e.g. a high backpressure with a large variation during operation of the steam turbine. In addition, the cooling behaviour of a direct air-cooled condenser is greatly affected by the environment, e.g. the wind and suspended dust in the air, and the condenser is easy to freeze when it operates in winter. The amount of dissolved oxygen in condensate water exceeds the limit set by the standard, and thermal pollution problem can not be neglected. The problems mentioned above were analyzed in this paper, and countermeasures were suggested.
