实践证明,锅炉隔烟墙穿孔,是导致烟气直接冲刷对流管,造成对流管泄漏事故的一个重要原因。 本文拟根据实践经验,对这个问题的起因和防止办法谈一些看法。 烟气在对流室中迂回流动,是靠隔烟墙来实现的。但是,由于形成隔烟墙主体的耐火砖和砖间填充材料耐火泥浆经常受到各种外因 Practice has proved that the perforation of the boiler wall across the smoke, flue gas is directly led to the convection tube directly, resulting in convection tube leakage is an important reason. This article is based on practical experience, on the cause of this problem and prevent some talk about some ideas. Flue gas in the convection chamber circuitous flow, is by the smoke wall to achieve. However, due to the fact that refractory muds, which form the bulk of the bulkhead,
