High temperature gradient gas mixer

A mixing system for a power generation system, the power generation system comprises a rotary machine, an exhaust processing system, and a duct system, the rotary machine is configured to produce an exhaust stream, the exhaust processing system is positioned to receive and process the exhaust stream, the duct system is oriented to channel an air stream to the exhaust processing system and to channel the exhaust stream from the rotary machine to the exhaust processing system, the duct system having a width defining a flow path therethrough, said mixing system within the duct system, said mixing system comprising:

• a plurality of supports spaced across the width of the duct system within the flow path, wherein each of said plurality of supports comprises a hollow tube defining a plurality of holes extending through said hollow tube;
• a plurality of links extending between at least two of said supports, wherein each of said links comprises a body and two pins extending from said body, and each of said pins is sized to extend through a respective one of said plurality of holes;
• and
• at least one wrap circumscribing at least two of said links within said flow path, wherein said at least one wrap is oriented to change an effective direction of momentum of the exhaust stream and the air stream.
