An invention is provided for a spiral flame torch apparatus. The spiral flame torch apparatus generally includes a base having a bottom plate, lower stabilization plate, and an upper stabilization plate. Situated on the base is a glass halo comprised of a plurality of rounded glass sheets. The glass sheets each include vertical sides that overlap one the vertical side of another rounded glass sheet, leaving gaps between the sheets. Disposed within the glass halo is a paraffin based flame source having a large wick disposed centrally within the flame source.

A fuel fired burner is provided for receiving a premixture of fuel and air. A ceramic flame support extends across the burner chamber and has a plurality of elongate slots through which the fuel and air flows. Each slot has a narrow constant dimension portion that opens into a wider constant dimension portion. The outlet end of the latter portion opens into a short diverging outlet. The arrangement is such that when the burner is operating within a given heat output range, the burner flame can move between the upstream and downstream ends of the diverging outlet to seek stabilization as the heat output changes within that range, without retracting into the slot upstream of the outlet.

A fuel fire burner has a plenum chamber to which fuel and air are supplied. One of the walls of the plenum chamber is generally flat and has a plurality of substantially rectangular slots extending therethrough, the slots serving as combustion ports for the fuel. The wall also has an integral rim extending therefrom on a side thereof opposite the plenum chamber.

A gas torch includes a base couplable to a gas source supplying gaseous fuel and gas ports formed in a top surface of the base to emit gas upwardly therefrom. A plurality of diverters is stacked in a spaced apart relationship directly above the base, each diverter having an inner edge and an outer edge. Each diverter is positioned above a lower diverter so that the inner edge and the outer edge are positioned intermediate one of the inner edge and the outer edge of the lower diverter. The lowest diverter, that which is adjacent the base, is positioned such that the gas ports are positioned directly underlying and intermediate the inner edge and the outer edge thereof.

Prior to annealing of cold rolled stainless steel strip, soot is deposited on the surface of the stainless steel strip by a soot generating burner, and thereby the heat absorption efficiency of the stainless steel strip in the annealing furnace is increased to enhance the heat treatment capability in the annealing furnace. This soot generating burner forms a flame by injecting a premixed gas at low air ratio of fuel gas and pure oxygen or high oxygen enriched air from the nozzle opening, and an air injection port for injecting air for guiding the flame is formed on the outer circumference of the nozzle opening. By this guide air, the flame is guided to form, so to speak, an air curtain, and it is therefore possible to direct the flame efficiently to the surface of the stainless steel strip, thereby preventing the soot from depositing near the nozzle opening.

A fuel gas burner adapted for mounting in a heat treating furnace and for generating a relatively large expanse of radiant energy toward an object to be heated or heat treated. The burner has a housing with separate inlets for fuel gas and air and an air plenum with a forwardly facing throat. Surrounding the plenum throat is a combustion block formed of refractory material shaped to define a forwardly-facing frusto-conical heat radiating surface. A central fuel gas supply tube coaxial with the plenum throat has a nozzle element and a cooperating distributor mounted on its forward end to define with the plenum throat an annular air passage and a fuel gas chamber communicating with the supply tube. The nozzle element has radially extending circumferential vanes that define with the plenum throat, swirl producing slots adapted to receive air from the plenum chamber through the annular passage and fuel gas through ports communicating with the fuel gas chamber. The resulting fuel-air mixture which has a swirling motion imparted by the slots is ignited and propelled radially outward against the frusto-conical surface of the combustion block to produce a generally flat-flame. This produces a relatively large expanse of heat radiation directed toward the area to be heated.

Aspects and features of a burner for a cooking appliance include a first plate defining flame ports arranged in flow-sharing groups around a periphery of a combustion surface and a second plate coextensive with the first plate. Each plate is contoured so that the plates define an annular void within the burner. The annular void is fluidly coupled to the flame ports. In some aspects, each flow-sharing group includes clusters of flame ports, with each cluster including flame ports of two different diameters. The plates can each be made using the same tool such as a die, stamp, or mold, and the burner can be sized and installed in a cooking appliance so that it extends to cover a large portion of a wall of the cooking cavity of the appliance.
