• 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.

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 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.
