FLAT-FLAME NOZZLE FOR BURNER

摘要

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.

主权项

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.
