Abstract
An improved radiant gas burner which includes a refractory burner tile hag an elongated passageway extending therethrough and a fuel-air mixture burner tube disposed within the passageway. The burner tube is of a one-piece elongated construction, includes a nozzle portion at the interior end of the passageway and is connected to means for introducing fuel gas and air therein by a threaded connection positioned adjacent the exterior end of the passageway. Secondary fuel is discharged from the passageway at a location adjacent the nozzle portion of the burner tube. An improved method of burning fuel gas and air using a radiant gas burner is also provided.
Claims13
In a radiant gas burner comprised of a refractory burner tile adapted to be inserted in a wall of a furnace and including an elongated passageway extending therethrough having an exterior end and an interior end, a burner tube disposed within the passageway having a nozzle positioned at the interior end of the passageway for directing a fuel gas-air mixture adjacent to the refractory burner tile within the furnace space, and means for introducing a fuel gas-air mixture into the burner tube attached thereto, the improvement which comprises:
- said burner tube being of a one-piece elongated construction and being connected to said means for introducing a fuel gas-air mixture thereinto by a threaded connection positioned adjacent to the exterior end of said passageway whereby said threaded connection remains relatively cool during the operation of said burner and said burner tube thereby remains selectively threadedly removable;
- said means for introducing a fuel gas-air mixture into said burner tube including a manifold block having a fuel gas-air mixture passage formed therein threadedly connected to said burner tube at one end and to a device for controlling the ratio of fuel to air at an opposite end, and
- means for sealingly connecting said manifold block to the exterior end of said burner tile passageway to thereby prevent the unregulated flow of air into said passageway attached to said burner tile and to said manifold block.
An improved radiant gas burner comprising:
- a burner tile mounting plate having an opening therein and supporting a refractory burner tile adapted to be connected in a wall of a furnace space, said burner tile having an elongated central passageway extending therethrough which is complimentary to said opening in said mounting plate;
- a sleeve sealingly attached to said opening in said mounting plate;
- a primary fuel gas-air mixture and secondary fuel gas manifold block sealingly connected to said sleeve whereby unregulated air flow is prevented from entering said passageway in said burner tile;
- a one-piece elongated burner tube disposed within said burner tile passageway having an inlet end threadedly connected to said manifold block and having a closed outlet end with a plurality of circumferentially spaced openings formed therein for directing a primary fuel gas-air mixture adjacent to said refractory burner tile within said furnace space;
- at least one secondary fuel gas discharge pipe connected to said manifold block and having the discharge end thereof positioned adjacent to the outlet end of said burner tube for injecting secondary fuel gas into said furnace space;
- means for introducing a primary fuel gas-air mixture into said manifold block and into said burner tube;
- and
- means for introducing secondary fuel gas into said manifold block and into said secondary fuel discharge pipe.
