Flue gas desulfurization (FGD) is a process that removes sulfur dioxide from the flue gas before its emission. This process is carried out during combustion in fossil fuel power plants such as coal and oil fired combustion units. When coal or oil is burned to produce energy, about 95% of the sulfur is converted into sulfur dioxide under standard temperature conditions. FGD can be characterized into wet & spray dry scrubbing, wet sulfuric acid process, SNOX flue gas desulfurization and dry sorbent injection system based on methods of desulfurization. Flue gas desulfurization technology has gained importance as a result of increasing air pollution due to sulfur dioxide released into the atmosphere during combustion processes. Flue gas desulfurization market has witnessed a significant growth in recent years due to stringent government policies relating to emissions of harmful gases in the environment.
But the corrosive environment is quite complicated, the condensed water solve the Sulfur Dioxide and Fluorine and form Acid which is strong corrosive material. The Alkali add to the corrosion. So the equipment calls for a good protection.
ZS-1041 Chimney and Flue Gas Duct Inner Wall Anti-Corrosion Coating adopts modified resin as film former. The main chain of resin is inorganic silicon polymer, grafted by organic polymer, forming network-structured polymer that contains advantages of both organic and inorganic materials. Such coating contains following fillers: nano-silicon powder, silicon carbide, fine-grained alumina, graphite, titanium oxide, ceramic cenosphere, zirconia powder. The cured coating has low surface energy, high hardness, high bonding force with substrate and excellent anti-corrosion property.
