目前由于国内经济的高速发展,导致国内大范围出现电力短缺的现象,所以发电厂机组的经济性一直被关注,发电厂机组真空系统的问题不但影响到机组的经济性,也会影响到机组的安全,尤其对于核电机组来说,还会危及到核安全。本文主要介绍了核电厂320MW机组凝汽器真空系统以及讨论凝汽器真空建立的相关参数,得出有关参数对影响凝汽器真空的影响,如循环冷却水进口温度、循环冷却水温升、凝汽器传热端差等对真空系统的影响,并针对核电厂320MW机组凝汽器真空的影响因素来分析应对这些因素的对策,提出了提高核电厂320MW机组凝汽器真空的建议与措施。
At present, due to the rapid development of the domestic economy, the power shortage in a large area in China has been a concern. Therefore, the economy of power plant units has been paid attention to. The problems of the vacuum system in power plant units not only affect the economic efficiency of units but also affect the Safety, especially for nuclear power units, is also endangering nuclear safety. This paper mainly introduces the condenser vacuum system of the 320 MW unit in nuclear power plant and discusses the relevant parameters of the condenser vacuum establishment. The influence of the parameters on the condenser vacuum is obtained, such as the inlet temperature of the circulating cooling water, the temperature rise of the circulating cooling water, Condenser heat transfer terminal difference on the vacuum system, and for the 320MW units of nuclear power plant condenser vacuum factors to analyze the response to these factors, proposed to improve the nuclear power plant 320MW unit condenser vacuum recommendations and measures .
