锅炉汽包水位是主要监视和控制的主要参数之一,锅炉启动过程中极为重要,汽包水位低,影响锅炉的正常水循环,汽包水位过低或汽包无水,造成锅炉水冷壁过热或爆管。汽包水位高,会使饱和蒸汽湿度增大,过热蒸汽温度降低,影响锅炉的正常启动,汽包水位过高或汽包满水会造成过热器进水、过热器水堵、主蒸汽温度下降、主蒸汽管道振动、汽轮机组过水被迫打闸停机。汽包水位的稳定直接关系到锅炉机组和汽轮机机组安全性。
Boiler drum water level is one of the main monitoring and control of the main parameters of the boiler is very important during start-up, low drum water level, affecting the normal boiler water cycle, drum level is too low or drum dry, causing the boiler water wall overheating or Squibs. Drum water level will make saturated steam humidity increases, superheated steam temperature decreases, affecting the normal start of the boiler, drum water level is too high or drum full water will cause superheater water, superheater water blocking, the main steam temperature drop , The main steam pipe vibration, turbine over water was forced to shut down. The stability of drum water level is directly related to the safety of boiler unit and steam turbine unit.
