Jul 07, 2019 · The emission and migration characteristics of flue gas mercury in a pilot-scale 0.3 MWth circulating fluidized bed combustion boiler system by injecting the adsorbent of ammonium bromide (NH 4 Br)-modified rice husk char (NBr-RHC) into the flue duct before a fabric filter (FF) were investigated in this study. Mercury concentration in the flue gas was sampled by the Ontario Hydro Method.Learn More

Jun 01, 2000 · Mercury exists primarily as gaseous (g) elemental mercury, Hg 0 (g), and as gaseous or solid (s) inorganic mercuric compounds, Hg 2+ X [e.g., where X is Cl 2 (g), SO 4 (s), O(s,g), S(s)], in coal combustion flue gas. Mercury emissions from coal-fired boilers can be empirically classified, based on the capabilities of currently available Learn More
Mar 16, 2009 · The Ontario Hydro Method was employed to detect mercury in flue gas, and HCl and Cl 2 were detected by the EPA method 26. A series of tests were conducted on the boiler with low‐NOx burners under various loads (70, 85 and of full load) and on the other boiler with conventional burners under full load.Learn More

Jun 01, 2019 · Mercury in flue gas consists of Hg 0, oxidized mercury (Hg 2+), and particulate mercury (Hg p) (Kim et al. 2010). Mercury speciation in flue gas emitted from boiler reveals the presence of primarily Hg 0 which is oxidized to Hg 2+ by reduction in temperature and reaction with halogen when it is passed through air pollution control devices (APCDs).Learn More
