Reformation of fanshaped plate gap control system for air preheater

Abstract

Abstract: Abstract:A part of air preheater control equipments of boiler No.5 in Huadian International Zouxian Power Plant was damaged, which caused that the gap control system can not be put into operation normally, the air leakage increased, and the boiler efficiency was affected. The fanshaped plate gap control system was reformed and brought into DCS to realize centralized control. After the reformation, the radial air leakage of the air preheater had been controlled effectively.
