Abstract: |
Coal-fired power plants are a main anthropogenic mercury emission source, and mercury as a global pollutant has drawn greater attention. The united States Environmental Protection Agency (US EPA) required that mercury should be monitored at the end emission locations of flue gas and be controlled. Four mercury sampling and analyzing methods was used to monitor mercury emission at stack of a coal-fired power plant. Mercury continuous emission monitors (Hg CEM), mercury sub-continuous emission monitors (Hg SCEM), Ontario-Hydro Method (OHM), sorbent trap mercury sampling (EPA Method 30B or Appendix K) were chosen. Mercury speciation transformation, merits and demerits, sampling characteristics and testing principle were investigated.
