    摘要: A rotary heat exchanger for preheating air using waste heat comprises a plurality of heat transfer elements movable between first and second openings in a housing to exchange heat between heated exhaust gases and a stream of fresh air. At least one heat transfer element comprises a first plate having a plurality of elongate notches formed therein at spaced intervals and oriented at a first angle relative to the flow direction. The plate further comprises a plurality of elongate undulations formed therein at spaced intervals and oriented a second angle relative to the flow direction, wherein the first angle is different than the second angle. A first height of each of said plurality of elongate notches is larger than a second height of each of said plurality of elongate undulations. The heat transfer elements may be stacked in a container for installation in the rotary heat exchanger.

    摘要: A lifting lug is disclosed for use with a low profile heater basket. The lifting lug can include a corner portion including first and second legs. The first and second legs are coupled to each other at respective first ends. The first and second legs can be oriented at an angle with respect to each other. The angle can be from 82.5-degrees to 97.5-degrees. The lifting lug can further include a hook engaging portion having first and second ends connected to respective second ends of the first and second legs. The hook engaging portion has a cylindrical cross-sectional shape. Further, an outer surface of the hook engaging portion is recessed from a bottom surface of a plane formed by bottom surfaces of the first and second legs. Other embodiments are disclosed and claimed.

    摘要: A heating surface element with a zig zag arrangement of longitudinal undulations which serve to minimize the skew flow of the gas. The angle of the undulations is preferably 15° to 35° to the primary flow direction of the gas. When used in combination with a notched heat surface element, the undulation preferably crosses no more than one opposing notch before changing direction.

    摘要: A stack of heating surface elements includes a first heating surface element (4) having first (10), second (12) and third (14) zones arranged sequentially along a primary gas flow direction (A). The first zone (10) includes a herringbone structure, the second zone (12) includes a flat structure, and the third zone (14) includes a plurality of corrugations extending in the primary gas flow direction (A). The corrugations have flat peak and trough regions. The stack also includes a second heating surface element (36), where the second heating surface element includes a plurality of corrugations extending in the primary gas flow direction (A).
