Abstract: The construction, operation and management of flue gas desulphurization facilities have great influences on coal-fired power plants and China started working on the sulfur dioxide emission reduction in coal-fired power plants in a large scale during the 11th Five-Year period. This paper reviews the history of the sulfur dioxide pollution control in coal-fired power plants, makes the summary and analysis from the aspects of policies, regulations, standards, technologies, equipment installation and operation, efficiency improvement as well as emissions control, and puts forward suggestions on total amount calculation method, desulfurization equipment management and comprehensive utilization of sulfur resources. The analysis shows that considerable progress has been made in the control of sulfur dioxide pollution in coal-fired power plants and remarkable results have been achieved on the total emission reduction , but the environmental benefit from the ultra low emission is still low and the new technologies need more improvement. The focus in the next phase should be on the systematic research and the sulfur dioxide concentration control.
