扬州第二发电厂２×６００ＭＷ机组采用了蓄能降压法的蒸汽吹扫系统，为了优化冲管系统，减少冲管时间，将原设计的第一阶段与第二阶段串联，使整个冲管系统分为两阶段，与三阶段方法相比，减少了冲管过程中的中间停炉改换临时系统。为防止吹扫中颗粒进入再热器，将临时管改为从冷再入口联箱前断开处接出。根据现场的实际情况，将系统的膨胀死点定位后，采用了滑动导向以及限位支架。临冲门采用压力等级为９００ＬＢ、ＤＮ６００的液压控制焊接式闭阀替代以往的电动闸阀。并增加了消音器，改变以往直吹排放，造成噪音污染环境。在２号机冲扫时，还有计划地增加了停炉冷却过程，通过这些措施，减少了冲管次数，节省了工期，降低了费用，减少了噪音污染，使冲管取得圆满的结果。
The second power plant in Yangzhou 2 × 600MW unit adopts the steam purge system of energy storage and depressurization method. In order to optimize the red tube system and reduce the red tube time, the first stage and the second stage of the original design are connected in series, The system is divided into two stages, which reduce the need for an intermediate shut-down change temporary system in the process of pipe-washing compared to the three-stage method. In order to prevent particles from entering the reheater during purge, the temporary pipe is changed to be taken out of the front of the cold re-entry header. According to the actual situation at the scene, the system will expand the dead point positioning, the use of sliding guide and limit bracket. Proboscis door with pressure rating of 900LB, DN600 hydraulic control welding valve to replace the previous electric gate valve. And an increase of muffler, change the straight blow emissions, resulting in noise pollution of the environment. In the second machine cleaning, there are plans to increase the shutdown cooling process, through these measures to reduce the number of red tube, save time, reduce costs, reduce noise pollution, the red tube to achieve satisfactory results.
