摘要： A heat transfer media that provides more complete and more even use of the media volume by enhancing the characteristics and/or directions of fluid flow across the media. The heat transfer media includes a heat transfer block having one or more layers that include longitudinal flow passages for enabling fluid flow in the longitudinal direction across each layer, and also include transverse flow passage for enabling lateral cross-flow between the longitudinal flow passages. The heat transfer block may include a plurality of stackable plates, with each plate having fins laterally spaced apart to define longitudinally extending channels, and at least one aperture extending transversely through at least one fin for enabling transverse cross-flow between the longitudinal channels. The aperture may be configured as a recessed groove in the fin, and the fin may have ridge portions longitudinally spaced apart to at least partially define the recessed groove.

摘要： A treatment apparatus for treating an effluent gas comprising:includes a combustion chamber; a burner; an inlet for receiving secondary combustion air; an exhaust gas outlet for outputting exhaust gases from the combustion chamber; and a heat exchanger. The heat exchanger is configured to exchange heat between a first fluid and a second fluid flowing through respective first and second fluid flow paths. The first fluid flow path is connected to the inlet such that the secondary combustion air flows from the inlet into the first fluid flow path and the second fluid flow path is connected to the outlet such that the exhaust gases received at the outlet flow into the second fluid flow path. The heat exchanger comprises a fluid flow communication path for providing a path for flow of a portion of the exhaust gases from the second fluid into the first fluid; and at least one inlet aperture for inputting the first fluid to the combustion chamber.

摘要： A fuel-fired heating appliance has two fuel flow paths to a burner, each actuatable to a closed state and to an open state. A heat exchanger is in fluid communication with an area proximate the burner. A controller executes the steps: (a) while the first fuel flow path is closed, opening the second flow path; (b) following ignition of fuel flowing from the second flow path, opening the first fuel flow path; and (c) following step (b), closing the second fuel flow path while opening the first fuel flow path.

摘要： Heat transfer sheets (70) for a rotary regenerative heat exchanger (10) have a alternating first and second undulation surfaces (71,81). The first and second undulation surfaces (71,81) are composed of parallel ridges (75,85) angled in alternating directions. When the heat transfer sheets (70) are stacked, they create passageways (79) between them that direct air/gas through them. The ridges (75,85) redirect the air flow near the surface of the heat transfer sheet (70) imparting turbulence reducing laminar flow to improve heat transfer. The heat transfer sheets (80) employ curved ridges (95) having valleys (97) between them that define passageways (99) that constantly redirect the air/gas flow minimizing turbulence, creating efficient heat transfer.
