Abstract: The principles and the methods of the flue gas sampling system, the mercury form transforming system and the mercury analysis instrument in different mercury online monitoring devices were analyzed, and their differences and similarities were compared. The practical application of the mercury online monitoring devices and their performance evaluation were introduced. Aiming at the problems, which may exist in flue gas mercury online monitoring in domestic coalfired power plants, and the next work, some suggestions were put forward.
