工业锅炉的汽包水位是运行中的一个重要参数,维持汽包水位是保持汽轮机和锅炉安全运行的重要条件,锅炉汽包水位过高会造成汽包出口蒸汽中水分过多,使过热器受热面结垢而导致过热器烧坏,同时还会使过热汽温急剧变化,直接影响机组运行的经济性和安全性;汽包水位过低则可能导致锅炉水循环工况破坏,造成水冷壁管供水不足而烧坏。
Drum water level of industrial boilers is an important parameter in operation. Maintaining the water level of the drum is an important condition for maintaining the safe operation of steam turbines and boilers. Too high water level in the drums of the boiler will result in excessive moisture in the steam from the steam drums and heat the superheaters Surface fouling caused by superheater burnout, but also make drastic changes in superheated steam temperature, a direct impact on unit economy and safety; drum level is too low may lead to the destruction of boiler water cycle conditions, resulting in water wall tube water supply Not enough to burn.
