Because of its light weight, corrosion resistance, high temperature resistance, aging resistance, high strength and many other characteristics, in 1987, the RWE thermal power plant in Weisweiler, Germany, adopted the limestone/gypsum desulphurization process in which both the desulphurization tower and the pipeline conveying the limestone slurry were made of FRP. After adding wear resistant fillers, FRP not only has the advantages of corrosion resistance, temperature resistance, high strength, but also has very strong wear resistance, at present, fiberglass reinforced plastics (FRP) has been widely used in wet desulphurization process, such as tower body, collecting tank, Mist Eliminator, spray pipe, slurry pipe, filter screen, oxidation air pipe (oxidation air spray gun) , pulse pipe, flue, chimney and so on.
