Definitions
- This invention concerns a gas burner.
- a gas burner including a body defining a combustion chamber, the body comprising a profiled integral member, with a plurality of ports being provided extending through a face of the body to provide a flame strip, with a combustion surface on the external side of the flame strip, the gas burner also including a frame member which is mounted to the body by a mechanical joint.
- the frame member and body may be mounted together by mechanical pressing.
- a flange may be provided around the body, and a part of the frame member may be folded around the flange.
- the body may comprise an at least generally planar part defining the flame strip, and side walls extending from the planar part, with the flange provided at opposite ends of the side walls from the planar part.
- the flame strip may be domed.
- Metal fibre may be provided on the exterior side of the flame strip.
- the metal fibre may be provided on only a part of the flame strip.
- the metal fibre may be provided on just a central part of the flame strip.
- the metal fibre may be mounted to the body by spot welding.
- a method of forming a gas burner comprising forming a plurality of openings in a piece of planar material to define a flame strip with ports therethrough, mechanically shaping the planar material to define a body, and mounting the body to a frame member by forming a mechanical joint therebetween.
- the body and frame member may be mounted together by pressing.
- a flange may be provided on the body, and the frame member may be profiled to engage on either side of the flange to provide a mechanical joint therebetween.
- Metal fibre may be mounted on an external side of the flame strip.
- the metal fibre may be mounted on the flame strip by spot welding.
- the metal fibre may be mounted on the flame strip prior to shaping of the planar material to form the body.
- Figs. 1 to 3 show a gas burner 10 of a type useable for instance in a central heating boiler, a cooking appliance or otherwise.
- the gas burner comprises a body 12 formed of an integral profiled sheet 14 of an appropriate metal.
- the body 12 has an upper slightly raised area which defines a flame strip 16 with a combustion surface on the external side of the flame strip 16.
- a layer of metal fibre 17 is mounted on the flame strip 14.
- a plurality of ports 18 are provided through the flame strip 16.
- the ports 18 may be in the form of circular holes or slots, or a combination of the two, or other shaped openings.
- a flange 20 is provided around the body 12 at the edges thereof away from the flame strip 16.
- a frame 22 is provided on the burner 10.
- the frame 22 comprises a peripheral strip 24 defining a central opening 26, with a pair of support members 28 extending across the opening 26.
- the body 12 is mounted to the frame 22 by the edges of the peripheral strip, being pressed around the flange 20.
- the ports 18 may be formed in the sheet 14.
- the sheet 14 can then be profiled to form the body 12.
- the frame 22 can be mounted on to the body by pressing edges of the frame on to the flange as shown in Fig. 1 .
- the metal fibre 17 extends across just a central portion of the flame strip 16, as is indicated by the lighter shaded ports 18 in Fig. 3 , with a row of ports 18 at each end and side not covered by the metal fibre 17.
- Fig. 4 shows a second gas burner 28 with a layer of metal fibre 30 extending wholly across the flame strip 16 and covering all of the ports 18.
- the metal fibre 17, 30 may be mounted to the body 12 by spot welding, and could be mounted on to the flame strip 16 during manufacture and prior to shaping of the body 12.
- the metal fibre 17, 30 is required to only cover a part of the flame strip 16, and may for instance only be required to cover a central part of the flame strip 16.
- the metal fibre is used to reduce or substantially eliminate noise or resonance during use of the burner. Leaving some of the ports uncovered by the metal fibre, provides for a retention of flame for instance with lean or poor gases, and thereby avoids nuisance shutdown of the burner.
