摘要
我国燃煤电厂近年来集中建设了大量SCR烟气脱硝装置,但由于运维技术水平不能满足实际运行需求导致大量问题未能及时预防,对电厂安全稳定运行造成不利影响。针对此现状,在总结分析当前SCR烟气脱硝装置运行现状的基础上,对典型的催化剂积灰磨损与空预器堵塞腐蚀问题的原因及应对措施进行了深入分析,并从提高运维技术水平与推广脱硝装置健康管理模式两方面对后续的运维对策提出了相应建议,以供后续燃煤电厂SCR烟气脱硝装置运行维护借鉴与进一步探讨。
A mass of SCR flue gas denitrification projects in thermal power plants have been constructed in recent years,but the operation maintenance technology can not meet the practical needs,causing an adverse impact on the safe and stable operation of thermal power plants. Aiming at the present situation,ash sticking eroding of catalyst and blockage erosion of the air pre- heater have been analyzed on the basis of summarizing the operation situation of the SCR equipment,and some suggestions have been proposed for further reference to the improvement of the following SCR operationmaintenance technology.
