| 摘要 |
The present invention relates generally to the field of emission control equipment for boilers, heaters, kilns, or other flue gas-, or combustion gas-, generating devices and, in particular to a new and useful method and apparatus for: (i) reducing halogen levels necessary to affect gas-phase mercury control; (ii) reducing or preventing the poisoning and/or contamination of an SCR catalyst; and/or (iii) controlling various emissions. In another embodiment, the method and apparatus of the present invention is designed to: (a) achieve a reduction in the level of one or more halogens, or halogen-containing compounds, necessary to affect gas-phase mercury control; (ii) achieve protection of, increase the catalytic activity, and/or increase the catalytic life span of an SCR catalyst; and/or (iii) achieve control of various emissions from a combustion process. |
