燃烧含硫重油的超临界压力锅炉,在运行中可靠性降低的主要原因之一是高温烟气的腐蚀。产生这种情况的原因之一是不完全燃烧的产物冲刷水冷壁管子。这时较“冷”的水冷壁管子附近就能形成活泼的腐蚀剂硫化氢。
One of the main reasons for the decrease of reliability in operation of supercritical pressure boiler burning sulfur heavy oil is the corrosion of high temperature flue gas. One of the causes of this is the incomplete combustion of the product flushing waterwall tubes. This time more “cold” water wall tube can form a lively hydrogen sulfide corrosion agent.
