Patent number: 11248850Abstract: A heat exchanger includes a separator member that divides a first flow passage from a second flow passage. The heat exchanger also includes a plurality of first hollow members that extend across the first flow passage at respective non-orthogonal angles. The plurality of first hollow members are fluidly connected to the second flow passage. Moreover, the heat exchanger includes a plurality of second hollow members that extend across the second flow passage at respective non-orthogonal angles. The plurality of second hollow members are fluidly connected to the first flow passage.Type: GrantFiled: August 8, 2019Date of Patent: February 15, 2022Assignee: HONEYWELL INTERNATIONAL INC.Inventors: Joseph Jensen, Jorge Alvarez, Francis Carbonell, Mark C. Morris, Donald G Godfrey, Karl Fleer

Patent number: 10222142Abstract: A heat exchanger may include at least one fluid passageway adjacent a heat transfer plate and a plurality of heat transfer elements positioned in the at least one fluid passageway and joined with the heat transfer plate. The heat transfer elements may be positioned with first spacings therebetween at an inlet end of the at least one fluid passageway. The heat transfer elements may be positioned with second spacings therebetween at an outlet end of the at least one fluid passageway. The first spacings may be smaller than the second spacings.Type: GrantFiled: February 27, 2017Date of Patent: March 5, 2019Assignee: HONEYWELL INTERNATIONAL INC.Inventors: Jorge D Alvarez, Douglas Czaplicki, Karl Fleer, Mark C Morris, Donald G Godfrey

Patent number: 6584760Abstract: Emissions are controlled in a recuperated gas turbine engine using an apparatus and/or method. A fixed boundary recuperator comprises a gas inlet through which flows a gas and a gas outlet in communication with the gas inlet. An air inlet flows an air through the recuperator so that the air is in heat exchange relationship with the gas. An air outlet is in communication with the air inlet. A catalyst is disposed at least at one of a plurality of locations, with the locations selected from the group that includes a position immediately upstream of the recuperator heat exchange core, a position within the recuperator heat exchange core, and a position immediately downstream of the recuperator heat exchange core. At least one parameter of the engine is tuned based on desired NOx emissions and remaining undesired emissions are catalyzed in or immediately adjacent a recuperator.Type: GrantFiled: September 12, 2000Date of Patent: July 1, 2003Assignee: Hybrid Power Generation Systems, Inc.Inventors: John Lipinski, Karl Fleer, Tony Prophet, Peter Zheng, Di-Jia Liu, George Lester

Publication number: 20020040576Abstract: A recuperator movable between a first position and a second position in or relative to a power generating system. When the recuperator is in the first position, a gas side inlet of the recuperator is coupled to a turbine exhaust outlet of the turbomachine. When the recuperator is in the second position, a gas side outlet of the recuperator is coupled to the turbine exhaust outlet, whereby the direction of gas flow inside the recuperator is reversed. Reversing the gas flow direction extends the life of the recuperator by reducing the total amount of time that the gas inlet face is exposed to high temperatures. Reversing the gas flow direction also allows for the removal of condensation of exhaust gas byproducts on cooler passage surfaces of the recuperator gas side. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to ascertain quickly the subject matter of the technical disclosure.Type: ApplicationFiled: October 31, 2001Publication date: April 11, 2002Inventors: Karl Fleer, Ahmed Hammoud
