Assignee:

The Babcock & Wilcox Company - New Orleans LA

International Classification:

F16L 1700

Appl. No.:

6/859278

Inventors:

David W. Gerber - Massillon OH
Frederick M. Untch - Canton OH

Assignee:

The Babcock & Wilcox Company - New Orleans LA

International Classification:

F28D 1704

US Classification:

165 4

Abstract:

A labyrinth articulation joint (38) for use in the seal frame (35) of a rotary regenerative air heater (20). An internal labyrinth arrangement of intercooperating tabs (54,55) and slots (44,45) in the two hinges (41,51) of the labyrinth articulation joint (38) present a series of successive right angle turns that increases the pressure drop through the labyrinth articulation joint (38) thus reducing the leakage of air through the labyrinth articulation joint (38), and thereby minimizing erosion of the labyrinth articulation joint (38) due to abrasive particles that would otherwise be carried through the joint by the leakage air.

Appl. No.:

6/521518

Inventors:

David W. Gerber - Massillon OH

Assignee:

The Babcock & Wilcox Company - New Orleans LA

International Classification:

F16L 2700

US Classification:

285 11

Abstract:

A floating seal for a rotating pipe joint joins two generally parallel and axially aligned pipes and provides a substantially fluid tight seal between them, while permitting relative rotation of the two pipes as well as limited relative lateral movement of the two pipes. The joint also accommodates dimensional changes, particularly in length, such as those generated by temperature change. A preferred embodiment includes a floating seal assembly having a plurality of spaced parallel circumferential grooves about the inner wall of the aperture which retain mating compression rings which are inwardly biased against the inlet pipe.
