Abstract

According to the present disclosure, a flat-flame nozzle is provided for producing a flat flame in a flame chamber included in a burner assembly. The flat-flame nozzle is configured to conduct fuel from a fuel supply to an ignition zone in the flame chamber. In some illustrative embodiments, the flat-flame nozzle is also configured to conduct oxygen from an oxygen supply to the ignition zone to produce a combustible oxygen-fuel mixture in the flame chamber. In illustrative embodiments, a removable first plate-separation border frame is positioned to lie between a first lower plate and a companion first upper plate. This border frame is configured to cooperate with those plates to form in the flat-flame nozzle a fuel-discharge outlet and a fuel-transport passageway communicating with the fuel-discharge outlet.

First claim

The invention claimed is:

1. A burner apparatus comprising:
a flat-flame nozzle configured to conduct fuel and to provide means for generating a flat flame when fuel conducted by the flat-flame nozzle is exposed to oxygen to produce an oxygen-fuel mixture that is ignited, wherein the flat-flame nozzle is formed to include a fuel-discharge outlet and a fuel-transport passageway communicating with the fuel-discharge outlet, and the flat-flame nozzle includes a first lower plate, a first upper plate, a removable first plate-separation border frame interposed between the first lower plate and the first upper plate and configured to cooperate with the first lower plate and the first upper plate to form the fuel-discharge outlet and the fuel-transport passageway, and fastener means for releasably retaining the removable first plate-separation border frame in a stationary position between the first lower plate and the first upper plate to establish a first flow velocity of fuel flowing through the fuel-transport passageway toward the fuel-discharge outlet and for allowing replacement of the removable first plate-separation border frame with a removable alternate first plate-separation border frame of a different thickness to establish a different second flow velocity of fuel flowing through the fuel-transport passageway toward the fuel-discharge outlet;
wherein the removable first plate-separation border frame is configured to include a first separator strip having a first thickness, a bottom gasket positioned to lie between the first lower plate and the first separator strip, and a top gasket positioned to lie between the first upper plate and the first separator strip.

2. The burner apparatus of claim 1 , wherein the removable alternate first plate-separation border frame is configured to occupy a space between the first lower plate and the first upper plate vacated by the removable first plate-separation border frame to establish the different second flow velocity of fuel flowing through the fuel-transport passageway toward the fuel-discharge outlet and the removable alternate first plate-separation border frame is configured to include a second separator strip having a different second thickness, a bottom gasket positioned to lie between the first lower plate and the second separator strip, and a top gasket positioned to lie between the first upper plate and the second separator strip.

3. The burner apparatus of claim 1 , wherein the fastener means includes several fasteners and each of the fasteners extends through a companion fastener-receiving aperture formed in each of the first lower plate, bottom gasket, first separator strip, top gasket, and first upper plate.

4. The burner apparatus of claim 3 , wherein each of the first lower plate and the first upper plate is rectangular and has perimeter portions formed to include fastener-receiving apertures and each of the first separator strip and bottom and top gaskets is U-shaped and arranged to cause an open end thereof to establish a portion of the fuel-discharge outlet.

5. The burner apparatus of claim 1 , wherein the first separator strip is made of stainless steel and each of the bottom and top gaskets is made of copper.

6. The burner apparatus of claim 1 , wherein the first upper plate is formed to include a shallow upper recess facing toward the first lower plate and arranged to lie in spaced-apart relation to the fuel-discharge outlet to locate the fuel-transport passageway therebetween.

7. The burner apparatus of claim 6 , wherein the first lower plate is formed to include a shallow lower recess facing toward the first upper plate and cooperating with the shallow upper recess and an inner edge of one of the removable first plate-separation border frame and the removable alternate first plate-separation border frame to form a fuel-receiving plenum configured to provide fuel distribution means for collecting fuel admitted into the shallow upper recess and distributing collected fuel into the fuel-transport passageway for downstream movement toward the fuel-discharge outlet and the fuel-transport passageway is arranged to conduct fuel discharged from the fuel-receiving plenum to the fuel-discharge outlet.

8. The burner apparatus of claim 6 , wherein the first upper plate includes an exterior surface facing away from the first lower plate and an interior surface facing toward the first lower plate and defining boundary portions of the shallow upper recess and the fuel-transport passageway, the first upper plate is formed to include a fuel-admission port having an inlet formed in the exterior surface and an outlet formed in the interior surface to open into the shallow upper recess, and further comprising a fuel-inlet pipe coupled to the first upper plate at the fuel-admission port and configured to conduct fuel into the shallow upper recess for subsequent movement through the fuel-transport passageway to and through the fuel-discharge outlet.

9. The burner apparatus of claim 6 , wherein the removable first plate-separation border frame is configured to include a first separator strip having a first thickness, a bottom gasket positioned to lie between the first lower plate and the first separator strip, and a top gasket positioned to lie between the first upper plate and the first separator strip, the fastener means includes several fasteners and each of the fasteners extends through a companion fastener-receiving aperture formed in each of the first lower plate, bottom gasket, first separator strip, top gasket, and first upper plate, each of the first lower plate and the first upper plate is rectangular and has perimeter portions formed to include fastener-receiving apertures and each of the first separator strip and bottom and top gaskets is U-shaped and arranged to cause an open end thereof to establish a portion of the fuel-discharge outlet, and each of the first separator strip and the bottom and top gaskets includes a first leg, a second leg arranged to lie in spaced-apart relation to the first leg, and a bight portion arranged to interconnect upstream ends of the first and second legs and lie in spaced-apart relation to the fuel-transport passageway, and the shallow lower recess is located between each of the bight portions and fuel-transport passageway and between each of the first legs and each of the second legs.

10. The burner apparatus of claim 1 , wherein the flat-flame nozzle is also formed to include a lower oxygen-discharge outlet and a lower oxygen-transport passageway communicating with the lower oxygen-discharge outlet and further comprising a second lower plate and a removable second plate-separation border frame interposed between the first and second lower plates and configured to cooperate therewith to form the lower oxygen-discharge outlet and the lower oxygen-transport passageway, and the fastener means is configured to provide means for releasably retaining the removable second plate-separation border frame in a stationary position between the first and second lower plates to establish a first flow velocity of oxygen flowing through the lower oxygen-transport passageway toward the lower oxygen-discharge outlet and for allowing replacement of the removable second plate-separation border frame with a removable alternate second plate-separation border frame of a different thickness to establish a different second flow velocity of oxygen flowing through the lower oxygen-transport passageway toward the lower oxygen-discharge outlet.

11. The burner apparatus of claim 10 , wherein the removable second plate-separation border frame is configured to include a first separator strip having a first thickness, a bottom gasket positioned to lie between the secon
