摘要
火力发电厂煤粉炉进行脱硝SCR工艺改造后,锅炉脱硝后的产物对低温省煤器及低温空预器产生了不良影响。介绍了锅炉脱硝改造后,脱硝副产物对低温省煤器管的腐蚀现象、原因分析和解决方案。
After the SCR denitration process of pulverized coal boiler in thermal power plant was transformed,the products after boiler denitration had a bad effect on the lowtemperature economizer and low-temperature air preheater.This paper introduces the corrosion phenomenon,cause analysis and solution of the by-products of denitration to the lowtemperature economizer pipe after the denitration transformation of the boiler.
