  • Patent number: 7600479
    Abstract: A method to reduce mercury in gas emissions from the combustion of coal is disclosed. Mercury emissions can be reduced by staging combustion process and/or reducing boiler excess oxygen. Fly ash formed under combustion staging conditions is more reactive towards mercury than fly ash formed under typical combustion conditions. Reducing boiler excess oxygen can also improve ability of fly ash to adsorb mercury.

  • Publication number: 20090211444
    Abstract: Method and a system for capturing mercury in a flue gas are provided. The method includes partially oxidizing a carbonaceous solid fuel in a gasifier such that a thermally activated carbon-containing solid sorbent and gaseous gasification products are generated wherein the gasifier is proximate to a combustion system for combusting a mercury containing fuel. The method further includes storing the generated thermally activated carbon-containing solid sorbent proximate to the combustion system and combusting a mercury containing fuel in a combustion zone of the combustion system wherein mercury released during combustion is entrained in flue gas generated by the combustion. The method also includes injecting the thermally activated solid sorbent in the flue gas downstream of the combustion zone and absorbing at least a portion of the entrained mercury on the thermally activated solid sorbent.
