Analysis of Abnormal Automatic Control of SCR Denitration Device in 660MW Ultra supercritical Coal-fired Units
This paper expounds the characteristics of the selective catalytic reduction denitrification system for 660MW coal-fired units.In response to the problems of equipment defects,improper logic,uneven distribution of NOx,and large ammonia escape that occur during the ultra-low emission process,resulting in the automatic long-term inability to put the denitrification system into operation and an increase in denitrification consumables,it explores the operating conditions and diagnostic strategies,and takes effective preventive measures.
