Patent number: 11933542Abstract: 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.Type: GrantFiled: November 17, 2022Date of Patent: March 19, 2024Assignee: Evapco, Inc.Inventors: Thomas W.

Publication number: 20230251038Abstract: Large scale field erected air cooled industrial steam condenser having heat exchanger bundles constructed with an integral secondary section positioned in the center of the heat exchanger, flanked by identical primary condenser sections. A bottom bonnet runs along the bottom length of the heat exchanger bundle, connected to the bottom side of the bottom tube sheet, for delivering steam to the bottom end of the primary condenser tubes 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 flow into the top bonnet from the primary condenser tubes and flow toward the center of the heat exchanger bundle where they enter the top of the secondary condenser section tubes. Non-condensables and condensate formed in the secondary section tubes enter a secondary bottom bonnet inside the primary bottom bonnet and are withdrawn from the secondary bottom bonnet via outlet nozzle.Type: ApplicationFiled: November 15, 2022Publication date: August 10, 2023Inventors: Thomas W. Bugler, Jean-Pierre Libert, Mark Huber

Patent number: 11719494Abstract: A new heat exchange tube fin design in which a plurality of arrowhead shapes are pressed into or embossed onto each fin, the arrowhead shape defined by two intersecting wedge sections. The pressed arrowhead shapes are grouped into nested pairs, and one of the arrowheads in a pair is pressed as a positive relative to the fin plane and the other of the pair is pressed as a negative relative to the fin plane. The arrowhead pairs are placed in rows parallel to the air flow direction and arrowhead pairs in one row are preferably staggered relative to the arrowhead pairs in the adjacent row along the fin in the air flow direction.Type: GrantFiled: November 2, 2020Date of Patent: August 8, 2023Assignee: Evapco Inc.Inventors: Thomas W.

Publication number: 20230051944Abstract: 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.Type: ApplicationFiled: August 15, 2022Publication date: February 16, 2023Inventors: Jean-Pierre Libert, Mark Huber
