An apparatus for heating water comprises a main burner, a pilot burner, a valve assembly with a main valve and a pilot valve having a shutter, a magnetic thermoelectric safety assembly with a thermocouple device holding the pilot valve open in the presence of a flame in the pilot burner, a button member mounted on a rod that is slidingly guided in the valve assembly and an electrical ignition member supplied via an electrical connection circuit, a switch device in the circuit being designed to be switched by means of the button member so as to close the electrical circuit when said button member is pressed in order to carry out actuation of the magnetic assembly so as to open the passage of gas through the pilot valve towards the pilot burner and to ignite the pilot flame by means of the sparks generated by the ignition member.

A torch igniter and a method of igniting a torch flame. An example embodiment includes a body including an oxidizer inlet configured to facilitate oxidizer flow through the body toward an output end of the body. The body includes a group of fuel inlet passages configured to distribute fuel in a direction tangential to the oxidizer flow through the body to create a swirling fuel-oxidizer mixture. A sparking element can be mounted on the body to produce a spark in the path of the swirling fuel-oxidizer mixture to ignite the mixture. The output end of the body is configured to emit a torch flame when the fuel-oxidizer mixture is ignited. Thus, a swirl torch igniter is configured for oxidizer and fuel flow through the igniter body to create an internal swirling fuel-oxidizer mixture to be ignited by a sparking element.

The invention relates to a re-ignition system for a gas device comprising an electrode element (1) provided next to a burner (2); an igniter (60) in communication with the electrode element (1) for transmitting electrical signal and providing a spark arc with high voltage towards burner (2) in electrode element (1) in ignition mode; and an ignition control unit (30). Re-ignition system further comprises at least one battery (10); a flame detection unit (50) receiving a flame presence signal (3) by flame rectification and a transformer (20) which converts the direct current supplied through the battery (10) from one inlet (22) to alternating current at an outlet (24) and is connected with the ignition control unit (30) and flame detection unit (50) to provide electrical signal.

An apparatus for heating water comprises a main burner, a pilot burner, a valve assembly with a main valve and a pilot valve having a shutter, a magnetic thermoelectric safety assembly with a thermocouple device holding the pilot valve open in the presence of a flame in the pilot burner, a button member mounted on a rod that is slidingly guided in the valve assembly and an electrical ignition member supplied via an electrical connection circuit, a switch device in the circuit being designed to be switched by means of the button member so as to close the electrical circuit when said button member is pressed in order to carry out actuation of the magnetic assembly so as to open the passage of gas through the pilot valve towards the pilot burner and to ignite the pilot flame by means of the sparks generated by the ignition member.

The hydrogen gas burner has a first pipe extendable into an oven chamber, having a plurality of through-holes in a sidewall thereof, fluidly communicating an interior of the first pipe with an exterior thereof. A combination gas valve and pressure regulator is connected to an inlet of the first pipe and fluidly connects a hydrogen gas source with the first pipe, such that the hydrogen gas flows into the first pipe and exits therefrom through the through-holes. An igniter ignites and initiates combustion of the exiting hydrogen gas. A second pipe is extendable into the oven chamber, having apertures in the sidewall thereof fluidly communicating an interior of the second pipe with an exterior thereof. The second pipe fluidly connects at an inlet thereof with an air source, whereby the air flows into the second pipe from the inlet thereof and exits out of the second pipe through the apertures.

A temperature sensor detects the presence of a flame by measuring the temperature near the flame site, and an actuator positions an ignition device in based on the temperature sensor's reading. The ignition device is positioned near the flame site if the flame is not present and further from the flame site if the flame is present.

An ignition switch assembly is configured to be operatively connected to a gas valve. The ignition switch assembly may include a first ignition contact and a second ignition contact. The first and second ignition contacts may be sized and shaped the same. A hub may be configured to be rotated within the ignition switch assembly. A rotation of the hub in a first direction causes a portion of the first ignition contact to engage the second ignition contact. Further rotation of the hub in the first direction or rotation of the hub in a second direction that is opposite from the first direction causes the portion of the first ignition contact to disengage from the second ignition contact.

A gas pipe ignitor for igniting a non-premixed air and fuel mixture includes a housing having an axially interior space along its length, a supply end segment, a flame end segment axially spaced from the supply end segment, and a flexible segment spaced between the supply end segment and the flame end segment. A fuel supply conduit extends axially within the housing, and the fuel supply conduit is operatively flexible with the flexible segment. An ignition conduit extends axially within the housing, and the ignition conduit is operatively flexible with the flexible segment. A detector conduit extends axially within the housing, and the detector conduit is operatively flexible with the flexible segment. An air supply conduit is operatively connected to the housing at the supply end segment and provides combustion air within the interior space.

An aspect of some embodiments of the current invention relates to a device, that may ignite a substance without the user directly causing the ignition. for example, the device may perform ignition in a manner that does not transgress Jewish religious prohibitions, for example the Jewish religious law prohibits kindling a flame on the Sabbath and/or festivals. In some cases, kindling may be permitted in an indirect manner referred to in Jewish law by the Aramaic term “Grama”. For example, the device may be designed to ignite a cigarette. Optionally, the device may be designed to be carried safely in a pocket. In some embodiments, the device may initiate ignition without direct user action and/or the initial ignition may be used to ignite another object in accordance with Jewish law allowing transfer of fire but prohibiting starting of a new fire on a holiday.
