Study on Different Measurement Methods of Mercury Emission in the Coal-fired Power Station
A simultaneous test between a dry and wet based SCEM system was conducted at ESP outlet of a power station. The data by the dry and wet based methods showed a similar changing trend, and the difference between the two is within an acceptable range. According to the analysis of the relative standard difference (RSD), it was found that the dry based method could provide higher quality data than the wet based method. The practical experimental process shows that the dry based method can work well for more time than the wet based method under unattended condition. The dry based mercury SCEM is expected to be a trend of the mercury SCEM and it is more possible for the dry based SCEM than the wet based SCEM to become a compact model and enter the control room in the power station to provide mercury concentration in the flue gas. At the other hand, as a new developing technology, the dry based SCEM needs more practical tests.
