An oil boiler according to the present disclosure includes a combustion chamber in which a combustion reaction occurs, a burner including a fuel nozzle that sprays fuel of an oil type into the combustion chamber, an air nozzle that injects air into the combustion chamber, and a spark plug that ignites a mixture of the fuel and the air, an air supply pipe that guides the air supplied to the air nozzle, a duct that releases combustion gas, a heat exchanger that heats heating water by heat from the combustion reaction, and a case that receives said components. The duct includes a flue connecting adaptor to which a corrugated pipe and a flue are connected, in which the corrugated pipe is connected to an inlet of the air supply pipe into which the air is introduced, and the flue releases the combustion gas to the outside of the case.

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 present disclosure relates to novel non-metallic ignition devices, and the method of making and using the novel non-metallic ignition devices.

An electronically controlled igniter device for a wick-containing item, and methods of use thereof, is described. The device is particularly advantageous in that it provides a convenient and safe device for igniting and optionally extinguishing the flame of a wick-containing item. The wick-containing item may be a standalone object, or a set of multiple electrically interconnected objects that can be individually controlled, or several groups of such objects may be remotely or locally controlled.

An igniter assembly comprising an ignition coil assembly connected to a firing end assembly by an extension, with a valve assembly disposed in a pressure chamber of the extension, is provided. The valve assembly includes a valve stem biased toward the ignition coil assembly by a spring to seal the pressure chamber. The valve assembly is used to evacuate contents from the pressure chamber by pressing the valve stem toward the spring and allowing contents of the pressure chamber to travel through and past the valve stem and out of the pressure chamber. The valve assembly is also used to fill the pressure chamber with an insulating medium by pressing the valve stem toward the spring and allowing the insulating medium to travel through and past the valve stem and into the pressure chamber after evacuating the contents out of the pressure chamber.

A gas turbine engine includes a combustion section space between a compressor section in a turbine section. The combustion section defines a combustion chamber and includes a combustor member defining an opening to the combustion chamber. A mounting assembly extends around or is positioned adjacent to the opening defined by the combustor member. In igniter extends through a ferrule of the mounting assembly and includes a distal end positioned proximate the opening in the combustor member. The igniter defines a plurality of channels each channel extending between a first end and a second end. The first end is positioned away from the distal end of the igniter relative to the second end, and the second end is a terminal end spaced from the distal end of the igniter.

A gas appliance includes a burner, a gas valve, an ignitor, a thermocouple, and a control device, wherein the control device is adapted to execute a control method comprising the following steps: controlling the ignitor to ignite and the gas valve to open; receiving a sensing voltage output from the thermocouple; stop the ignitor from igniting and controlling the gas valve to keep a gas pipe be in an open state when the sensing voltage increases to a first voltage; receiving the sensing voltage output from the thermocouple continuously, and controlling the gas valve to block the gas pipe when the sensing voltage decreases from higher than a second voltage to lower than the second voltage, wherein the second voltage is higher than the first voltage. Whereby, an ignition procedure could be speeded up and the gas could be blocked earlier as the flames are extinguished.

A cartridge for use in a smoking device for vaporization including a first area for including a smokeable material, a second area for including a vapor-forming material, and a perforation allowing vapor to exit the cartridge upon heating the cartridge.

An ignition system includes a pulverized fuel pipe receiving a mixture of pulverized fuel and primary air for injection into a combustion chamber for combustion, and an igniter received within the pulverized fuel pipe for igniting the mixture. The igniter is axially movable within the pulverized fuel pipe.
