在自然资源短缺的情况下,煤价也呈现出一种逐渐上升的趋势,导致火力发电厂的运营成本持续增加.在此种情况下,大部分电厂通过采购劣质煤、掺烧煤泥的方式来降低运营成本,但是却出现了锅炉水冷壁结焦、高温腐蚀问题.基于此种情况,研究以某电厂燃烧器对冲布置电站锅炉为例,首先分析造成侧墙水冷壁结焦、高温腐蚀的原因,其次,借助X射线荧光光谱、X射线衍射分析锅炉结焦、高温腐蚀机理,最后,并提出相应的解决对策.通过分析设备改造后的应用效果发现,锅炉结焦、高温腐蚀的情况得到有效缓解,达到了预期效果,在一定程度上提升了企业的经济效益与社会效益.
Study on the Coking and High Temperature Corrosion of the Water Cooling Wall on the Side Wall of a Power Plant Boiler with Burner Opposite Arrangement
In the case of shortage of natural resources,the coal price also shows a rising trend,leading to the continuous increase of operating costs ofthermal fuel power station.In this situation,most power plants reduce operating costs by purchasing inferior coal and blending coal slurry,but there are problems with coking and high-temperature corrosion of boiler water walls.Based on this situation,it takes the boiler of a power plant as an example to analyze the causes of coking and high-temperature corrosion on the side wall water-cooled wall.Secondly,the mechanism of boiler coking and high-temperature corrosion is analyzed using X-ray fluorescence spectroscopy(XRF)and X-ray diffraction(XRD).Finally,corresponding solutions are proposed.By analyzing the application effect of the equipment renovation,it was found that the situation of boiler coking and high-temperature corrosion has been effectively alleviated,achieving the expected effect and improving the eco-nomic and social benefits of the enterprise to a certain extent.
