胜利发电厂1号国产200MW机组凝汽器改造采用管系置换法,即采用新排管设计,并合理调整冷却管支撑间距更换冷却管的方法在大修期内对旧凝汽器进行改造,改造后相对真空提高2kPa,相应热耗下降137.2 kJ/(kW·h),效果明显。这种对旧凝汽器改造方案是全面提高凝汽器性能的有效方法。
In the overhaul period, the condenser of the domestic 200 MW unit of Shengli Power Plant No. 1 was retrofitted with the piping replacement method, that is, the new piping design was adopted and the cooling pipe support spacing was adjusted reasonably to replace the cooling pipe. During the overhaul period, the old condenser was retrofitted and rebuilt After the relative vacuum increased 2kPa, the corresponding heat loss decreased 137.2 kJ / (kW · h), the effect is obvious. This solution to the old condenser retrofit is an effective way to fully improve the performance of the condenser.
