The invention relates to a burner with surface burning, which comprises a burner head (12) having a housing (14), which has a supply (18) for a fuel-air mixture upstream and has a fabric membrane (16) downstream on an outlet side and comprises a flame flash-back barrier (17), which is arranged upstream of the fabric membrane (16) at a distance to this, wherein at least the fabric membrane (16) and the flame flash-back barrier (17) are arranged by at least one releasable connection element (54) which engages with a receiving region (47) in the housing (14).

An infrared radiator for the heat treatment of a material web has an incandescent body with a flow-receiving surface that is subjected to a flow of a gas-air mixture supplied to the infrared radiator and heated by combustion of the gas-air mixture. The incandescent body is manufactured as a sheet material formed of a multiplicity of threads and connecting elements that at least indirectly connect the threads to one another. The connecting elements at least partially engage around the threads and thus connect them at least indirectly to one another. The connecting elements are configured in such a way that they may be detached from the connection with the threads, preferably by hand, while breaking up the sheet material.

A fuel nozzle assembly includes one or more tapered fuel nozzles. Each tapered fuel nozzle includes an acute trailing edge or tip at a top portion of the fuel nozzle. One or more fuel orifices are arranged proximate the acute trailing edge or tip. A tapered fuel nozzle having a toroidal airfoil structure includes a fuel channel to distribute a fuel to the fuel orifice(s). The fuel nozzle assembly may be provided as part of a burner system, including a perforated flame holder, and associated method, in which the fuel nozzle assembly is oriented to direct fuel from the fuel orifices toward the perforated flame holder.

A burner has a dual use pot whereby the pot can be machined to provide for single flow control to inner and outer flame rings (directly related to each other) as a single flow configuration or maintained in a dual flow configuration whereby a user can separately control flow to inner and outer flame rings (independently related to one another). A lateral passage is fed from an inlet to feed outer flames while a transverse passage possibly elevationally displaced from the transverse passage for some embodiments can feed the inner ring. The lateral and transverse passages are joined to be in fluid communication through the method taught herein.

The present device relates to a system of gas burners, in particular for a cooking top for household use and including a pair of substantially concentric burners. The pair of burners including an outer burner equipped with a first base, a first burner body and a first flame divider, and an inner burner equipped with a second base, a second burner body and a second flame divider. The present device is characterized in that the first base of the outer burner and the second base of the inner burner are made from a metallic sheet that is shaped by deep drawing.

A gas burner (1) comprises a support plate (2) with a passage opening (8) for the gas and an annular wall (11) formed around the passage opening (8), a diffusing wall (19) and a further flow element (20,21,22) inserted on the annular wall (11) in flow communication with the passage opening (8), wherein the annular wall (11) forms a plurality of punches (16) with a recess (17) and an opposite projection (23), wherein the recess (17) accommodates a locking protuberance (25) of the diffusing wall (19) and the projection (23) extends in a locking hole (24) of the further flow element (20, 21, 22).

A burner tip for installation in a burner, wherein the burner tip has a surface facing a combustion chamber, an air channel structure leading to the surface and defining an air channel, and a fuel channel structure leading to the surface, and wherein the fuel channel structure defines a fuel channel, which extends in a surface region of the burner tip in a first direction parallel to the surface and then extends back, at least in part, in a second direction, different from the first direction, in order to cool the surface region of the burner tip by a fuel flowing through the fuel channel during operation of the burner tip.

A portion of a submerged combustion burner is disposed into a pressure vessel. The portion of the submerged combustion burner has a welded area that has a first microstructure defined by a first number of voids. The vessel is filled with an inert gas, pressurized, and heated. Pressurizing and heating operations are performed for a time and at a temperature and a pressure sufficient to produce a second microstructure in the welded area of the burner. The second microstructure is defined by a second number of voids less than the first number of voids.

The present disclosure is related to a dual ring gas burner wherein the outer ring includes multipoint injection with bottom breathing and the inner ring works with top breathing. Two flame rings are included along with burner ports on the caps. As a result, better heating distribution is achieved along with greater ease in cleaning and combined simmer functions with high ratings by having the outer ring gas flow not interfering with the inner ring.

A multi-tube burner system for efficient mixing of fuel and air for combustion is disclosed. The multi-tube burner system includes an air supply plenum, a multi-tube burner, and a combustor. Further, the multi-tube burner includes a set of tubes including the air supply section to receive combustion air and supply the received combustion air to a mixing section. Furthermore, the multi-tube burner includes a set of fuel pipes to receive fuel from a set of fuel inlets and supply the received fuel to a set of fuel plenums. Furthermore, a pair of fuel receiving channels receive the fuel from the set of fuel plenums and a fuel injector pin injects the received fuel from the pair of fuel receiving channels to the mixing section. Further, a set of mixing holes allow egression of the combustion air and the fuel mixture from the mixing section to the combustor.
