摘　　要：针对电厂凝汽器真空度普遍偏低的情况,提出了以新型的LT板式换热器取代现在的管壳式凝汽器.在对板式换热器和管壳式换热器的性能进行比较的基础上,以某电厂300 MW机组凝汽器为例,对改造方案进行技术经济分析,结果表明方案可行.In view of the low condenser vacuum, a new method that put a plate heater exchange（LT） to replace a tube heater exchange used in power plant condenser was proposed. Based on comparison of the performance of the plate heater exchange and the tube heater exchange, a 300 MW power plant condenser was taken as an example. A reform programme was proposed and the technical and economical analysis was researched, it shows that the scheme is feasible.
