Claims
- 1. A burner plenum, for use with a burner apparatus, configured for receiving combustion air and gaseous fuel from a gaseous fuel manifold, for mixing same for delivery to a desired location for ignition of the mixed gaseous fuel and combustion air, for promoting the production of a stabilized flame for providing heat to be transferred to a location remote from the burner apparatus, comprising:
- a plurality of side walls, defining an interior volume comprising a mixing region having a substantially constant width and a substantially constant thickness and a pressure recovery region disposed downstream from the mixing region, having a substantially constant width;
- an inlet plate, connected to the side walls at one end of the burner plenum, and having means for enabling injection of gaseous fuel from at least one gaseous fuel outlet into the interior volume of the burner plenum,
- the inlet plate further having means for enabling ambient air to be drawn into the interior volume of the burner plenum by a suction source disposed downstream of the burner plenum.
- 2. The burner plenum according to claim 1, wherein the means for enabling injection of gaseous fuel comprises:
- at least one gas inlet aperture disposed in the plate member, for receiving therethrough a jet of gaseous fuel being emitted from at least one gaseous outlet of a gaseous fuel manifold.
- 3. The burner plenum according to claim 2, wherein the means for enabling ambient air to be drawn into the plenum comprises:
- a plurality of air inlet apertures, substantially surrounding the at least one gas inlet aperture, so that ambient air can be drawn into the interior volume of the burner plenum by a suction source disposed downstream of the burner plenum.
- 4. The burner plenum according to claim 1, wherein the interior volume further includes a pressure recovery region, the burner plenum further comprising:
- a baffle member, positioned within the pressure recovery region of the interior volume, for facilitating distribution of the mixed gaseous fuel and combustion air across the width of the burner plenum and for facilitating distribution of the mixed fuel and air across a burner plate disposed in an outlet region of the burner plenum.
- 5. A burner plenum, for use with a burner apparatus, configured for receiving combustion air and gaseous fuel from a gaseous fuel manifold, for mixing same for delivery to a desired location for ignition of the mixed gaseous fuel and combustion air, for promoting the production of a stabilized flame for providing heat to be transferred to a location remote from the burner apparatus, comprising:
- a plurality of side walls, defining an interior volume;
- an inlet plate, connected to the side walls at one end of the burner plenum, and having means for enabling injection of gaseous fuel from at least one gaseous fuel outlet into the interior volume of the burner plenum,
- the inlet plate further having means for enabling ambient air to be drawn into the interior volume of the burner plenum by a suction source disposed downstream of the burner plenum,
- wherein the side walls defining the interior volume of the burner plenum, further comprise:
- a mixing region having a substantially constant width and a substantially constant thickness; and
- a pressure recovery region disposed downstream from the mixing region, having a substantially constant width and a substantially continuously increasing thickness.
- 6. The burner plenum according to claim 5, wherein the side walls of the burner plenum defining the pressure recovery region are operably configured for association with a burner plate, for directing mixed gaseous fuel and combustion air to the burner plate.
