| Abstract: | Direct air-cooled condenser of power generating unit is liable to occure condenser tubes freezing in lower temperature of winter, aiming at the problem, analyzing the traditional preventing frostbite measures and combining with the structure characteristic of direct air-cooled condenser, puts forward a set of safe and reliable prevent frostbite measures. The result shows that using the elec- tric shutters device to prevent frostbite of direct air-cooled condenser has prominent maneuverability, timeliness, preventing frostbite effect and on the safe side. |
