A swirler includes a swirler body defining a longitudinal axis. A stack of swirler plates is assembled to the swirler body stacked in a direction along the longitudinal axis. Each of the swirl plates defines a vane portion. The swirler plates are mounted rotated circumferentially about the longitudinal axis relative to neighboring ones of the swirler plates so the vane portions form a swirler vane.

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).

The disclosed technology includes a combustion system providing ease of access to components of the combustion system and optimal placement of a burner such that efficient combustion and heat transfer can occur. The combustion system can include an inner tube having a first end and a second end, the second end having a flange with a sensor port, and an outer tube having a first end and a second end. The inner tube can be disposed within the outer tube. The inner tube can have an outer diameter less than an inner diameter of the outer tube, creating a gap between the outer tube and inner tube. An ignitor assembly and a flame sensor assembly can extend through the sensor port and the gap and be positioned proximate a burner.

Adjustable gas grill burners are disclosed. Methods of making and using adjustable gas grill burners are also disclosed.

A method for assembling a fuel distribution system for a turbomachine fuel injector includes inserting a liquid fuel distributor into an interior cavity of a shroud to create a liquid fuel distribution circuit between the liquid fuel distributor and the shroud and inserting a gas fuel distributor into the interior cavity of the shroud and into an interior cavity of the liquid fuel distributor to create a gas fuel distribution circuit between the gas fuel distributor and the liquid fuel distributor. The method includes inserting a fuel transfer tube into an outer diameter of the shroud. The method includes brazing or shrink fitting at least one of the fuel transfer tube, the gas fuel distributor, or the liquid fuel distributor to the shroud.

A cooking appliance includes a cooking area. A hob can be located in the cooking area. The hob includes an injector holder base defining an air chamber and a burner interface chamber. An injector holder cover overlies the injector holder base. The injector holder base and the injector holder cover collectively define a venturi tube extending between the air chamber and the burner interface chamber. An injector is carried by at least one of the injector holder base or injector holder cover. A burner is supported on the injector holder cover.

An evaporator subassembly for mobile heating devices, in particular for a motor vehicle, having the following: an evaporator, an evaporator receptacle which is constructed to receive the evaporator, a glow plug and a combustion chamber, wherein the glow plug extends or is constructed to be extensible obliquely relative to a main surface of the evaporator into the combustion chamber.

The invention relates to a burner as well as to a waste gas treatment device for generating a flame for the combustion of process gas, especially of contaminants, in a combustion chamber, in each case having feed lines for a fuel gas and for an oxidizing agent so that they flow into a pre-mixing chamber, and having an ignition device for igniting the gas mixture contained in the pre-mixing chamber. According to the invention, a sensor for detecting and/or monitoring the flame is provided on the burner, especially at one end of the burner situated opposite from the pre-mixing chamber.

A method for assembling a fuel distribution system for a turbomachine fuel injector includes inserting a liquid fuel distributor into an interior cavity of a shroud to create a liquid fuel distribution circuit between the liquid fuel distributor and the shroud and inserting a gas fuel distributor into the interior cavity of the shroud and into an interior cavity of the liquid fuel distributor to create a gas fuel distribution circuit between the gas fuel distributor and the liquid fuel distributor. The method includes inserting a fuel transfer tube into an outer diameter of the shroud. The method includes brazing or shrink fitting at least one of the fuel transfer tube, the gas fuel distributor, or the liquid fuel distributor to the shroud.

A heat source device including a sheet-metal burner body (30), a fan casing (40) connected to the burner body (30), an annular packing (90) connecting a burner-side connection end surface (340) with a fan-side connection end surface (410) in an airtight state, a sheet-metal connection part (80) disposed between the burner-side connection end surface (340) and the fan-side connection end surface (410), wherein the connection part has an opening (85) and a packing storage portion (84) storing the annular packing (90), wherein the opening (85) is provided in such a manner that an opening edge is positioned outside of those of an inlet port (35) and a blowout port (44) in a state where the connection part (80) is disposed between the burner-side connection end surface (340) and the fan-side connection end surface (410).
