一、前言无论是火力发电站,还是原子能发电站,发电用原动机都是蒸气涡轮机。从蒸汽涡轮机排出的蒸气进入冷凝器,在那里冷却变成水,再送入锅炉或原子能反应堆。原子能电站用冷凝器是非常大的机器。例如,1100MW原子能电站的冷凝器,传热面积约为70000m~2,冷却管根数约73000根,而且重量也有1700吨。所以在工厂制造后, I. Preface Whether it is a thermal power station or an atomic power station, the prime mover for power generation is a steam turbine. Vapor from the steam turbine enters the condenser, where it is cooled and turned into water before it is sent to a boiler or nuclear reactor. Atomic power plant condenser is a very large machine. For example, the condenser of a 1100MW nuclear power plant has a heat transfer area of ​​about 70,000m2, a cooling pipe of about 73,000 and a weight of 1,700 tons. So after the factory is manufactured,
