A flame sense assembly (100) includes a flame sense electrode having a sense rod (108), at least a portion of the sense rod (108) for placement in a flame area; and an electrically conductive ground screen (110) for electrical connection to ground, at least a portion of the ground screen (110) for placement in the flame area; wherein the ground screen (110) is positioned relative to the sense rod (108) to allow an electric current to pass between the sense rod (108) to the ground screen (110) in the presence of a flame.

Provided are a remote controllable auto-ignition candle and a control system thereof, and more particularly, a remote controllable auto-ignition candle including a wick portion performing combustion after ignition and including a wick made of a conductive material; a first communication unit communicating with a user terminal in a wired or wireless manner; a control unit controlling an ignition state of the wick portion according to a control signal received through the first communication unit; and an ignition means generating a discharge to the wick so that the wick portion is ignited according to a control of the control unit.

An improved and high capacity gas igniter for furnaces and burners. The igniter can include an igniter tip that is annular in shape and includes various holes of different sizes and angular projections distributed throughout. The igniter tip may utilize a slip-joint-like mechanism or sleeve that connects inner and outer tubes of a guide tube that allows the inner tube to slide when undergoing thermal expansion. This configuration alleviates stress from building up on the inner tube and igniter tip, preventing damage.

Systems and methods herein provide retractable and extendable portable ignitors, ignitor systems, and associated methods for lighting industrial fired equipment. In an embodiment, an ignitor includes a main body including a first body portion movable in a longitudinal direction relative to a second body portion so as to extend or retract to a target operating length, thereby to define an adjustable main body. The ignitor includes a flow path extending through the adjustable main body, a fluid outlet, and a fluid inlet. The fluid inlet is configured to receive and direct a fuel flow through the flow path and to the fluid outlet. The ignitor includes a sparking assembly connected to the adjustable main body proximate the fluid outlet to provide an ignition spark to the fuel flow when passing through the flow path, thereby to facilitate lighting industrial fired equipment via a fueled flame maintained proximate the fluid outlet.

One or more techniques and/or systems are disclosed for an ignition control module for a gas appliance. The housing of the ignition control module, and/or the mounting points for mounting the module to a gas appliance, can be configured to dispose the battery in a manner that provides for potential battery leakage to flow away from most operable components of the module. Further, the ignitor connection terminals can be configured to provide for ease of connection, by providing a connector guide disposed in a cylindrically-shaped terminal housing. Additionally, an ignitor actuator terminal can be configured to selectably engage with an ignitor actuator connector, where the ignitor actuator terminal comprises at least two connector points that engage with a single ignitor actuator connector.

A spark plug having a capacitor formed therein and a semi-surface gap, wherein the capacitor permits a high-impulse discharge to occur across the semi-surface gap and the pronounced effects of the Lorentz force, due to the high voltage and high current discharge, cause the spark to project axially away from the end of the spark plug.

An automatic smoker, which ignites a combustion medium placed in a combustion chamber by means of an automatic igniter. An ignition needle of the automatic igniter is positioned inside an air inlet port and extends into the combustion chamber, placing the ignition needle at an upwind position. When the ignition needle performs the ignition operation, air enters the combustion chamber through the air inlet hole, promoting the combustion of the combustion medium, thereby enabling the automatic igniter to ignite the combustion medium within the combustion chamber more easily and quickly.

An automatic ignition and extinguishing candle comprising a candle body with one or two wicks, an electric arc lighter or arc generating circuit for ignition, a fan-based air blower for extinguishing, and a motion sensor for triggering the extinguishing. The single wick version utilizes an electric arc lighter with two electrodes positioned beside the wick, while the two-wick design employs wicks made of combustible and electrically conductive materials, allowing the wicks themselves to serve as electrodes for arc generation. The motion sensor detects nearby motion and activates the air blower to extinguish the flame. Additional features may include a microcontroller for overall control, manual ignition and timed extinguishing capabilities, remote control operation, sound and light sensors for automatic ignition, and specific wick structures and conductive coatings. This invention provides a safe, convenient, and automated way to control the ignition and extinguishing of candles.

The ignition system holds a quantity of a reaction mixture in a hopper. The hopper is closed at the bottom by a movable gate. When the gate is opened, powder falls from the hopper, though a passage, and through an ignition chamber. High voltage electrodes are provided in the ignition chamber. As the powder falls through the ignition chamber, the electrodes are energized, generating an electrical arc. The arc ignites the falling powder. The ignited powder falls from the bottom of the chamber and into the reaction chamber of an exothermic mold, where the ignited powder initiates a thermite reaction that generates molten metal to form an exothermic weld.

An automatic smoker includes a smoker body, a pipe and a base. The pipe has a combustion chamber, an inner wall of the combustion chamber is defined with at least one smoke outlet por. The smoker body and the base are detachably assembled, and the pipe is arranged between the smoker body and the base. The smoker body includes an automatic igniter, the automatic igniter includes an ignition needle, the ignition needle extends into the combustion chamber and is configured to ignite a combustion medium within the combustion chamber.
