Abstract

Abstract: The limestone blind zone, which occurred in Inner Mongolia Huadian Baotou Power Generation Company Limited, was studied in depth. The features and the formation mechanism of limestone blind zone were analyzed and described. The relevant treatment methods and preventive measures were put forward, which can be used as reference for related technical staff.

Key words: limestone-gypsum wet flue gas desulphurization, limestone blind zone, slurry poisoning, reason analysis, treatment method
