Methods and apparatus for removing mercury from combustion flue gas

Image Number 5 for United States Patent #7531153.

A method for reducing an amount of mercury in flue gases generated by the combustion of coal is provided. The method includes combusting a quantity of coal and a quantity of air within a primary combustion area such that a fly ash containing carbon and elemental mercury is formed within the flue gases, supplying air to the primary combustion area such that a portion of the air is channeled to an overfire air burnout area downstream from the primary combustion area to facilitate increasing an amount of the carbon content in the fly ash, cooling the flue gases to facilitate oxidizing the elemental mercury using the carbon content in the fly ash, and injecting sorbent into the flue gases to facilitate further reducing the amount of mercury in the flue gases.
