Large scale field erected air cooled industrial steam condenser having heat exchanger panels with primary and secondary condenser sections, in which the secondary condenser section comprises 10% or less of the total heat exchanger, and in which the tubes of the primary condenser sections have narrowed outlet orifices having an area that is 50% or less than the cross-sectional area of a corresponding tube. The invention permits the reduction of secondary condenser tubes while reducing the outlet header pressure sufficiently to minimize backflow, sweep non-condensables and prevent the formation of dead zones.

Heat rejection devices, including cooling towers, condensers and closed circuit coolers, having side-mounted backward-curved centrifugal fans mounted on top of the device, above a fan plenum instead of a top-mounted axial fan. Heat rejection capability can be easily modified by adding or subtracting fans without impacting unit footprint. Also, the ability to handle higher static pressures allows for the use of a more densely packed heat exchanger in the same footprint unit, which will increase the unit performance.

Large scale field erected air cooled industrial steam condenser having heat exchanger panels independently loaded into and supported in a heat exchange frame section. A bottom bonnet runs along the bottom length of each heat exchanger panel for delivering steam to the bottom end of condenser tubes in the heat exchange panel and for receiving condensate formed in those same tubes. The tops of the tubes are connected to a top bonnet. Uncondensed steam and non-condensables are drawn into the top bonnet from the condenser tubes. A steam distribution manifold is suspended from the heat exchange section frame perpendicular to the longitudinal axis of the heat exchange panels and beneath a center point of the heat exchange panels and delivers steam to each heat exchange panel via a single steam inlet located at a center point of each bottom bonnet.

A non-electromechanical, pumpless liquid recirculation system for adiabatic pre-cooling and evaporative heat exchange systems featuring an ejector device including motive fluid nozzle and an annular recirculating fluid chamber surrounding the nozzle. Motive make-up liquid under pressure is expelled from the nozzle into a mixing chamber. Recirculating fluid is introduced to and entrained with the motive make-up liquid at the outlet of the nozzle, and the motive force of the make-up liquid forces the combined make-up liquid and recirculating liquid out through the outlet of the ejector device to a water distribution system for the heat exchange system.

An adiabatic cooling system includes a condenser coil and one or more adiabatic pads positioned such that intake air for the adiabatic cooling system passes through the pads prior to contacting the condenser coil. The adiabatic cooling system includes a vibration device attached to each adiabatic pad. A controller is communicatively coupled to the vibration device for each of the adiabatic pads. The controller determines that cleaning of the adiabatic pads is needed. In response to detecting cleaning is needed, the controller causes the vibration device attached to each adiabatic pad to vibrate, thereby causing debris in the one or more adiabatic pads to become loosened and/or removed from the adiabatic pads.
