Exhaust plume control structure and power generating plant including same

A power generating plant, including:

• a power generating system, the power generating system creating an initial exhaust flow;
• a stack configured to direct the initial exhaust flow to atmosphere;
• and
• an exhaust plume control structure, including:
• a mounting member configured to mount to the stack, the mounting member including a plate having an opening defined therein in fluid communication with the initial exhaust flow;
• a diverter member operatively coupled to the mounting member to radially direct an initial exhaust flow exiting from the exhaust flow source radially outward;
• and
• a plurality of peripherally spaced, radially extending vanes coupled to the mounting member and disposed radially outward of the diverter member, the plurality of peripherally spaced vanes positioned to separate the radially outward directed initial exhaust flow into a plurality of additional exhaust flows, each vane of the plurality of peripherally spaced vanes having a radially diverging cross-section having a first side extending at a first angle relative to a given radius of the diverter member and a second side extending at a second angle relative to the given radius of the diverter member, wherein the first angle and the second angle are not identical, each of the plurality of additional exhaust flows having a same radial exit velocity,
• wherein the diverter member extends into the opening of the plate to radially direct the initial exhaust flow from the power generating system across each of the plurality of peripherally spaced vanes.
