Horizontal venturi burner construction

摘要

A horizontal venturi burner has at least one burner ring, if not several, supplied by respective ports which supply air/fuel mixture thereto. The ports are directed at orifice holders which are received in receivers preferably formed in cast top and bottom pots. The receivers may have openings on either side which allow single direction installation of the holders and preferably prevent rotation by having adjacent and cooperating flats/faces therein, as well as openings which properly position the holders in a desired axial arrangement.

1. A horizontal venturi burner comprising:
a first burner ring supplied with a gas/air mixture from a first port, said first port having a first inlet; a pot top and a pot bottom connected together forming a first receiver, the first receiver having a first planar face; a first orifice holder having a middle section with a first planar flat and a first protrusion spaced from and directed toward the first inlet of the first port wherein gas directed through the first orifice holder mixes with air introduced through the first inlet of the first port, wherein the first flat is adjacent to the first planar face thereby preventing the first orifice holder from rotating relative to the first receiver, and the middle section is entrapped within the first receiver preventing axial movement along a gas flow axis when installed.
