ABSTRACT:
A method of reducing particulate matter and mercury emissions in a combustion flue gas includes, in an exemplary embodiment, combusting a fuel resulting in generation a flue gas flow, cooling the flue gas flow within a duct, positioning a flow conditioning apparatus within the duct, enhancing a reaction rate of the mercury and carbon-containing fly ash particles by directing the flue gas flow through the flow conditioning apparatus to mix the carbon-containing fly ash particles and mercury within the flue gas flow and to facilitate at least one of oxidation of the mercury and binding the mercury to the carbon-containing fly ash particles, collecting a portion of the carbon-containing fly ash particles in the flow conditioning apparatus, and directing the flue gas flow to a particulate collection device to remove the remaining portion of the fly ash particles from flue gas flow.
