Burner

摘要

A gas burner including a burner body having a lower housing, an inlet conduit and a combustion surface element attached to the lower housing. A diffuser/reflector positioned within the body encourages even distribution and mixing of a combustible gas/air mixture. The diffuser/reflector is preferably of a sheet metal construction and includes a plurality of stamped openings with each of these openings having an overhanging guide plate. The combustion surface element includes a plurality of integrally formed rigidizing ribs and is made from a high temperature steel alloy wire cloth. The inlet conduit is secured directly or indirectly to an access door/bulkhead that is used to close off an access opening formed in a water heater wall through which the burner is installed. In one construction, an air scoop shrouds the inlet conduit and at least partially defines a flow path of primary air, substantially isolated from the combustion chamber.

1. A gas burner comprising:
a) a burner body including:
i) a lower housing said lower housing having a sidewall;ii) a steel alloy screen element defining a combustion surface attached to said lower housing;iii) a diffuser/reflector positioned below said element; b) an inlet conduit communicating with said burner body through which a gas/air mixture is delivered to said burner body in a region located below said diffuser/reflector wherein said inlet conduit extends at least partially into said burner body; and, c) said diffuser/reflector including a plurality of openings, each opening having an overhanging guide plate; d) said diffuser/reflector having a somewhat inverted V-shaped configuration, and said openings are arranged in sets of parallel rows and said diffuser/reflector including a second plurality of openings located in an upper region of said diffuser/reflector which do not include associated guide plates; e) said openings of said parallel rows being oriented to direct said gas/air mixture in a direction generally toward said sidewall, said direction being generally transverse to an axis of said inlet conduit.
