摘要
脱硫吸收塔喷淋层支撑梁在运行过程中被浆液冲刷,严重时会出现吹损穿孔,威胁系统的安全稳定运行。结合华能玉环电厂4×1000 MWe燃煤机组脱硫装置运行过程中喷淋层支撑梁出现的吹损穿孔实例,探讨了百万机组单炉单塔脱硫装置喷淋层支撑梁发生吹损穿孔的原因和防吹损的措施。
The spray layer backbar of the desulphurization absorption tower is scoured by the slurry,and serious scouring may cause blowing loss perforation,and the safe and stable operation of the system was threatened.Combining with the practical blowing loss perforation in spray layer backbar of 4×1000MWe unit desulphurization of Huaneng Yuhuan Power Plant,the reason of the blowing loss perforation in spray layer backbar of 1000MWe unit single boiler and single tower desulphurization equipment and the blowing loss ...
