Ronald Moulder - Newark OH

Assignee:

The Marley Company - Mission Woods KS

International Classification:

F22B 718
F22B 3740

US Classification:

122 131

Abstract:

A gas boiler having a boiler unit constructed by interconnected boiler sections each having an internal waterway bounded by one or more heat transfer surfaces. Baffles on the boiler sections define serpentine flue passages, and the baffles include bypass openings formed by notches and/or slits to suppress standing waves and associated noise. A burner includes a conical burner element having burner ports arranged in clusters to enhance the flame distribution and stability. A distributor cone nested within the burner element provides a pressure drop for noise suppression. The blower shaft is equipped with a magnetic plastic washer which effects a seal against air infiltration while allowing the blower shaft to shift from side to side.
