Anticorrosive Modification Technology and Application of Brick Sleeve Chimneys
In order to solve the problem that the acid contained in the flue gas will corrod the inner tube of the brick after wet desulfurization,which will cause acid leakage and lead to the collapse of the inner tube,it is necessary to carry out anti-corrosion transformation of this type of chimney.During the renovation,it is necessary to install the PENNGUARD anti-corrosion system on the inner wall of the brick inner cylinder,anti-seepage treatment of the expansion joint,acid collection and drainage system and the construction of the anti-icing system at the chimney top.This paper introduces a set of anticorrosive technology and construction scheme of brick sleeve chimney based on the example of anticorrosive renovation project.
