蒸汽锅炉是石油,化工,电力(火电厂)等工业部门的主要能源设备。锅炉汽包液位是保证锅炉安全运行的主要条件之一。液位过高,使蒸汽产生带液现象,不仅降低了蒸汽的产量和质量,而且,还会使过热器结垢,或使汽轮机叶片损坏;当液位过低时,轻则影响水汽平衡,重则烧干锅炉,严重时会导致锅炉爆炸等事故,所以锅炉水位是一个很重要的被控对象。
Steam boiler is the main energy equipment in the industrial sector such as petroleum, chemical industry, electric power (thermal power plant) and so on. Boiler drum level is to ensure the safe operation of the boiler one of the main conditions. Liquid level is too high, so that the steam generated liquid phenomenon, not only reduces the steam production and quality, but also make superheater fouling, or damage to the turbine blades; when the liquid level is too low, ranging from light water vapor balance, Heavy boil dry boilers, serious cases can lead to boiler explosion and other accidents, so the boiler water level is a very important target.
