Special stainless steel lining of wet stack in FGD system of coalfired power plant for corrosion prevention

Abstract

Abstract: Abstract:The corrosion property of wet stack and selection of anticorrosion material were discussed. Based on the experiment, the anticorrosion property, the mechanical property and the welding performance of the superaustenitic stainless steel XDS5, which is used as special anticorrosion lining of wet stack, were analyzed. The analysis result shows that XDS5 is an excellent material for anticorrosion lining of wet stack. At last, the thin plate pasting process was introduced. The widespread application of alloy in wet stack and even whole wet FGD system is useful for stability and reliability of the system operation, and the life cycle costs of the equipments can be reduced.

Key words: Keywords:flue gas desulphurization (FGD) system, wet stack, corrosion, superaustenitic stainless steel, thin plate pasting
