Application of Organic Polymer Anticorrosion Lining in Power Plant Waste Heat Boiler Chimney Anticorrosion Retrofit
Flue gas waste heat recovery is an important technology to improve the thermal efficiency of thermal power plant units.In the process of unit modification,the reduction of exhaust temperature will exacerbate the corrosion of flue gas condensate on the chimney and flue,which will cause a greater safety hazard to the unit operation.In order to ensure the safe and stable operation of the unit,it is necessary to carry out anticorrosion modification of the tail flue and chimney of the unit's waste heat boiler.For different conditions of flue gas in the tail flue of waste heat boilers,different processes of anticorrosion coatings are used to isolate the inner wall steel cylinder from contact with wet flue gas and condensate,thus providing anticorrosion protection.This paper describes the anticorrosion transformation program in the actual transformation process of gas power plants,aiming to provide reference for the practical application of elastic(toughness)polymer anticorrosion lining materials.
