Sulfur dioxide pollution generated by coal-fired power generation , is a global problem , limestone - gypsum wet desulphurization technology in the field of coal-fired power plant flue gas desulfurization , the most widely . In China , is building a 600MW unit flue gas limestone - gypsum wet desulphurization engineering design capabilities , project cost and other factors , there are still a lot of problems . In this paper, on the basis of the study of domestic and foreign coal-fired thermal power unit flue gas desulfurization technology Pannan Power Plant coal characteristics Pannan Power Plant 600MW unit # 3, # 4 flue gas limestone - gypsum wet desulphurization project for flue gas the the desulfurization process system design optimization, optimization of selected coal sulfur content design parameters , the optimal selection of the absorber design parameters . At the same time , consider that the site layout , operation and maintenance and other factors , to develop a reasonable process system , select the appropriate process equipment to ensure system reliability and reduce the impact on the safe operation of host ; anticorrosive the Pannan power plant desulfurization , the paper also targeted the sexual conduct optimal choice of anti-corrosion materials and optimized design of the program . Limestone - gypsum wet desulphurization process , different systems equipment , work environment and corrosive media , equipment corrosion requirements , studies have shown that Pannan flue gas desulfurization project as a major anti-corrosion materials , glass flake resin , anticorrosive design and construction , at the same time reduce the project cost , to ensure the high reliability of the system . Also on the disc wet flue gas desulfurization project of the South power plant absorption tower overflow , water balance , anti-corrosion damage and pipeline Chenjiao loss and other problems , preliminary research and exploration , and in practical application , targeted to take some countermeasures and treatment measures . Some measures taken to obtain the desired results .
