摘要
针对国内某1000MW机组大修期间加装凝汽器在线清洗装置,在相同凝汽器热负荷和海水条件下,加装在线机器人清洗装置进行清洗后,凝汽器总体传热系数由改造前的3.13kW/(m2·K)提高到5.19kW/(m2·K);改造后凝汽器较改造前下降0.56kPa,发电煤耗降低约1.24g/kWh。机组正常运行后通过投切凝汽器在线冲洗装置再次验证了清洗装置的实用性。
As for the installation of condenser online cleaning device during the overhaul of a 1000MW unit,after the installation of online robot cleaning device,the overall heat transfer coefficient of the condenser increased by 5.19kW/(m2·K)from 3.13kW/(m2·K)before the renovation under the same condenser heat load and seawater condition.After the transformation,the condenser decreased by 0.56kPa,and the coal consumption of power generation decreased by about 1.24g/(kW·h).After the unit runs normally,the practicability of the washing device is verified again by the online cleaning device.
