Flue gas desulfurization is the main measure for controlling sulfur dioxide emissions in coal-fired power plants today, and limestone-gypsum wet desulfurization is currently the most widely used and most mature process in the world. Therefore, the wet desulfurization system has extremely strict requirements on the corrosion resistance, wear resistance and temperature resistance of the materials. The glass fiber reinforced plastic desulfurization tower can fully meet the requirements in the use process due to its excellent corrosion resistance, light weight, high strength and high design ability.
