Abstract: Water intake structures for power plants and other industrial facilities may include an inflow channel, a deep well, an outflow channel, and an intake channel These structures may include a fish screen, such as a wedge-wire screen or the like, positioned between the deep well and the intake channel to separate fish, fish larvae and fish eggs from water supplied to the intake channel from the deep well. These structures may further include one or more circulating or sweep flow pumps positioned proximate an outlet of the outflow channel. The sweep flow pumps may be used to maintain a sweep flow through the deep well of the intake structure to help sweep fish, fish larvae and fish eggs away from the fish screen and into the outflow channel.

Abstract: An application and process that incorporates an external heat source to increase the temperature of the airstream entering a compressor section of a combustion turbine. The application and process may perform an anti-icing operation that may not require an Inlet Bleed Heat system (IBH) to operate. Additionally, the application and process may perform an anti-icing operation that may allow for the IGV angle to remain nearly constant. The application and process may increase the output and efficiency of a combustion turbine operating at partload by delaying IBH operation and delaying the closing IGVs.

Abstract: A deep chilled air washer for a gas turbine compressor. The deep chilled air washer may include one or more spray arrays for chilling an inlet air stream and one or more drift eliminators positioned downstream of the spray arrays. The drift eliminators may include a heating element therein so as to reheat the inlet air stream.

Abstract: High temperature thermal energy storage system comprised of solid-liquid phase change material that is fully encapsulated in helically grooved, sealed, thin-wall, metal tubes. Multitude of horizontally oriented, pressure-rated steam pipes or vessels filled with PCM tube capsules form a battery of thermal storage system. The steam pipes in the battery are connected through a common liquid-side distribution header system and a common steam-side distribution header system. Multitude of steam pipes stacked up to fill a block-shaped container space. This insulated enclosure provides the basis for simple fabrication, transport and filed-erection and forms the basic building block for a modular thermal storage system.

Abstract: Multi Effect Distiller (MED) with vertical flat-plate, falling-film heat transfer mechanism. A multitude of alternatively arranged or “checkered”, rectangular shaped evaporator and condenser cells form one layer between two vertical flat plate walls. Multitude of layers—each comprised of alternating evaporator and condenser cells—form the block-shaped MED unit. The evaporator and condenser cells are against each other, sharing common vertical heat transfer walls. The simultaneous propagation of multi effect distillation occurs in two dimensions along the longitudinal vertical plane of the heat exchanger. One end of the distiller is heated, while the other end is cooled.
