The generation and emission of SO_3 in SCR system of coal-fired boilers has an adverse influence on the operation of the power plants and air quality
and will endanger human health. Some countries and regions have set strict emission standards for SO_3. The SO_3 collaborative removal technology has been promoted and applied. The application of ultra low temperature electric dust collectors
electrostatic fabric filter and wet electrical dust precipitator has significantly improved the SO_3 removal efficiency. This paper investigates the formation
removal and detection of SO_3 in coal-fired power plants in detail
reviews the research progress of SO_3 flue gas control technology in denitrification devices
dust removal facilities and desulfurization systems
and compares the advantages and disadvantages of various SO_3 detection technologies. On this basis
it proposes the future development direction of the SO_3 collaborative removal technology.
