根据有关资料介绍,我厂采用低压自激快速启动方法,对20kW,50kW单相高温盐炉进行了技术改造。经半年时间的实践及应用取得良好节电效果。现就技术改造情况及操作中应注意的问题介绍如下。 1.设计应注意的问题由于低压自激型快速启动是靠人工造渣降低极间电阻,通过极间电弧使固体盐快速熔化,因此在设计时应考虑以下几个方面: According to the introduction of relevant information, our factory adopts the low-voltage self-excited rapid start-up method to carry out technological transformation of 20kW, 50kW single phase high temperature salt furnace. After six months of practice and application of good energy-saving effect. Now on the technical transformation and operation should pay attention to the problem described below. 1. Design should pay attention to the problem Since the low-voltage self-excitation type quick start is based on artificial slag to reduce the resistance between the electrodes, through the arc between the solid salt rapid melting, so the design should consider the following aspects:
