Abstract: A gas turbine exhaust diffuser includes a frustoconical portion that defines an interior surface and an axial centerline. In particular embodiments, the interior surface may have a slope greater than 6 degrees, 10 degrees, or 20 degrees with respect to the axial centerline to define an axial cross-sectional area of at least 200 square feet, 240 square feet, or 260 square feet. In other particular embodiments, the interior surface may have an axial length of less than 25 feet or less than 10 feet. A helical turbulator on the interior surface of the frustoconical portion may reduce flow separation between exhaust gases and the interior surface to enhance recovery of potential energy from the exhaust gases.

Abstract: An exhaust gas recirculation (EGR) mixer for use in a power generation system is provided. The EGR mixer includes a mixing chamber defining a flow direction and a working fluid inlet coupled with the mixing chamber for introducing a working fluid into the mixing chamber along the flow direction. The EGR mixer also includes exhaust gas injection ducts extending across the mixing chamber downstream from the working fluid inlet. Each of the exhaust gas injection ducts is oriented to receive exhaust gases being recirculated within the power generation system and to inject the exhaust gases into the mixing chamber in a direction that intersects the flow direction to generate a turbulent flow within the mixing chamber. The EGR mixer also includes an outlet coupled with the mixing chamber for directing a mixture of the exhaust gases and the working fluid to a compressor within the power generation system.

Abstract: An anti-icing system for a gas turbine system includes multiple nozzles, wherein each nozzle of the multiple nozzles includes one or more outlets that are configured to inject a heated fluid into an airflow within an air intake conduit. The anti-icing system also includes multiple plates disposed upstream of the one or more outlets, wherein each plate of the multiple plates extends laterally across the air intake conduit and is vertically spaced apart from one or more adjacent plates to define one or more vertically-extending gaps. The multiple plates are configured to direct the airflow through the one or more vertically-extending gaps to spread the airflow upstream of the one or more outlets to facilitate mixing of the heated fluid and the airflow.

Abstract: An exhaust plume control structure includes a mounting member configured to mount to an exhaust flow source. At least one divider member operatively couples to the mounting member and is positioned in fluid communication with the exhaust flow source. A diverter member operatively couples to the divider member(s) to radially direct an initial exhaust flow from the exhaust plume towards the divider member(s). Each divider member separates the initial exhaust flow into a plurality of exhaust flows. A number of peripherally spaced, radially extending vanes may also separate the exhaust flows into additional exhaust flows. Each of the additional exhaust flows has a slower velocity than the initial exhaust flow. The structure reduces exhaust flow velocity and may provide back pressure to the initial exhaust flow. A power generating plant including the structure is also disclosed.
