Abstract: An apparatus for controlling gas valves in a gas drier is provided. The apparatus includes an igniter, a closed flame detection switch and a sustaining relay. The igniter, which starts a flame, connects to a first terminal which provides a power signal with respect to a neutral terminal. The closed flame detection switch is connected between the igniter and the neutral terminal thereby receiving the power signal via the igniter. The closed flame detection switch also detects a flame by opening. The sustaining relay provides an alternative path of conduction with respect to the closed flame detection switch.

Abstract: A burner having an elongate, generally tubular sheet metal body having an inlet end, a closed distal end and a tubular segment extending between the ends. The inlet end is formed to define a gas orifice holder which is adapted to mount a gas orifice element. The inlet end is further formed to define at least one primary air opening arranged to admit primary air from a source of primary air. Rows of flame ports are defined in the tubular segment and are arranged to create a desired predetermined flame pattern. When used as a fireplace burner the flame ports may be slot-like in construction and include tabs which determine the effective size of the ports. In a fireplace application, flame ports located below a crossover log, are eliminated and/or formed of reduced size, thus providing a flame of lower height and/or less intensity, thus substantially eliminating sooting.

Abstract: The aim of the invention is to produce a spray burner, starting from a conventional spray burner, for the atomisation and combustion of sulphur-containing residues, comprising a residue nozzle, for the introduction of sulphur-containing residue, which is surrounded by an outer nozzle, for the introduction of an atomising agent, whereby said burner is suitable for a method in which oxygen can be introduced in the cracking oven as additional oxidising agent to increase the capacity and improve the economic efficiency without the above disadvantages and limitations and is also optimised for a variable throughput of residue for atomising. Said aim is achieved whereby the residue nozzle comprises a multiplicity of individual nozzles which may be switched on and off, connected to an input for the residue, an inlet for fuel is provided and the outer nozzle is connected to an inlet for an oxygen-enriched gas stream.

Abstract: A cooking device with a muffle bounding a cooking space, a linear door for closing a muffle opening and a drive device for moving the linear door to open or close the cooking space. In order to increase the operational reliability the cooking device has an anti-trapping device which detects an object outside the muffle opening between the inside of the linear door and a front face of the muffle frame. The anti-trapping device prevents trapping of the object between the linear door and the front face of the muffle frame when the object is detected.

Abstract: A miniature combustor comprising a combustion chamber having at least one critical dimension that is sub-centimeter. Combustion is confined within the chamber by injecting a liquid fuel as a film over substantially the entire area of the chamber walls. In a preferred embodiment, a swirl or vortex generator may be included at the entrance of the chamber to cause the in-flowing oxidizing gases to swirl within the chamber. The liquid fuel may be applied as a film through one or more orifices or a porous wall material, or may be applied by spraying the fuel on a surface within the chamber. The liquid fuel may be augmented with an inert liquid such as water.

Abstract: The present invention is directed to an apparatus for use in cooking over an open fire. Specifically, the invention discloses a tripod having a grill suspended therefrom. The tripod includes an elongate adjustment rod with a distantly situated handle. By attaching the suspension line, holding the grill to the handle, which is slidingly affixed to one leg of the tripod, the height of the grill over the fire can be changed. This arrangement allows the grill to be adjusted over the fire to accommodate the heat of the fire or to provide a preferred cooking temperature for the articles on the grill without adjusting the grill directly or having to touch the hot surfaces near the fire.

Abstract: A cooking appliance includes burners having ports that are aligned in a defined alignment with respect to an adjacent structure of a burner body or the cooking appliance within a piloting zone so that the adjacent structure guides the formation of a flame kernel at an outlet of the port. The adjacent structure may be ports which also form flame kernels withing the piloting zone of the burner port outlet, a structural portion of the burner body such as an extended lip protruding beyond the burner port or a separate structure such as a flame rod or other target that stabilizes the flame kernels at the burner port outlet. Such structures provide a method for improving the turndown ratio of burners by preventing lifting or backlash of the flame kernels generated at the burner port outlets by aligning the ports in conjunction with an adjacent structure within a piloting zone.

Abstract: An exhaust hood (125, 225, 325, 425) captures and contains a thermal plume (170, 370, 470) with a minimum of exhaust air by defining a short-throw vertical curtain jet (150, 350, 453) around a protected perimeter. The jet augments the formation of a vortex (135, 335) within the hood which extends beyond the hood protected by the curtain jet. The effect is the extension of the buffer volume of the hood recess. This reduces the fluid strain that generates the turbulent eddies that cause breach of containment. Also, the curtain jet augments the vortical flow which is stable and contains less fluid strain than would otherwise occur. The hood recess is shaped to assist in defining the above vortex in terms of both its shape and its size. For example, the recess may be made smooth-walled according to an aspect of the invention.
