A spacer for a fluid nozzle can include a body configured to fit within a sheath of the fluid nozzle such that a fluid tube positioned within the sheath is held bent over its longitudinal dimension by the body thereby altering a natural frequency of the fuel tube compared to if the fuel tube were not held bent.

Cooktop appliances are provided. A cooktop appliance can include a gas burner; a manifold having a gas input; a primary line extending between the manifold and the gas burner, wherein a gas flow rate in the primary line is controllable by a user selectable interface; and a secondary line extending between the manifold and the gas burner, wherein a gas flow rate in the secondary line is controllable by a flow control valve.

A torch device for household and construction applications is disclosed. The torch device includes a body that is shaped like a firearm having an aft handgrip, a forward handgrip, a trigger guard, and an igniter guard. The body provides a more convenient carriage of the torch and integrates safety features for the torch device. A fuel delivery assembly is coupled with a fuel source. An igniter is carried within the body and operable via the igniter guard. A nozzle tip is coupled with the torch head to discharge the fuel source into a torch head. A fuel delivery conduit communicates the fuel source between the nozzle and a trigger control operable via access through the trigger guard. The torch device provides for easier carriage and safer operation while conducting repair and maintenance tasks.

The disclosure provides a burner and a gas-fired clothes dryer, where the burner includes a combustion barrel, a barrel-shaped gas mixing part and a disc-shaped flow guide part, the combustion barrel has a gas inlet, a barrel wall of the combustion barrel is uniformly provided with a plurality of vent holes; the gas mixing part is arranged in the combustion barrel and parallel to an axis of the combustion barrel, a gas inlet end of the gas mixing part is opposite to the gas inlet; the flow guide part is arranged in the combustion barrel and located between a gas outlet end of the gas mixing part and a closed end of the combustion barrel and inclined relative to the axis of the gas mixing part; a diameter of the flow guide part is between a diameter of the combustion

A gas turbine engine may include a combustion section having a fuel nozzle, a swirler, and a ferrule configured to mount and center the fuel nozzle with the swirler. The combustion section may further include a damper on a cold side of the combustion section. The damper may have an acoustic cavity, a damper neck, and a cavity feed hole. The damper may operate as Helmholtz cavity to absorb a hydrodynamic or acoustic instability present in a region within the swirler.

Smooth, heat-treated glass fragments are created by placing a plurality of heat-treated glass fragments into a tumbling or vibrating apparatus. Each heat-treated glass fragment is formed from glass that has been heated to a temperature of at least 1000° Fahrenheit and rapidly cooled to a temperature below 800° Fahrenheit. The plurality of glass fragments is then tumbled or vibrated for a predetermined period of time such that surfaces of the heat-treated glass fragments are smoother than prior to tumbling. The glass fragments are thereafter removed from the tumbling apparatus, resulting in smoothed, heat-treated glass fragments that have a slightly rounded, bead like-shape and are suitable for direct handling without hand protection. The glass fragments as are able to be provide radiant heat in the temperature range of 400° to 800° Fahrenheit. This temperature range and the use of the heat-treated glass fragments provides for a clean burning fire that virtually eliminates any soot and carbon monoxide while burning.

A burner device includes a fuel tank and an ignition unit. The fuel tank includes a chamber, a first thread portion, and a check valve including a valve body. The ignition unit removably attached to the fuel tank. The ignition unit includes a second connecting portion engageable with the first thread portion, and a top pillar selectively to push against the valve body of the check valve to slide along a longitudinal axis. When the fuel in the fuel tank is depleted during the operation, a user can use a filling assembly to fill the supplemental fuel into the fuel tank or replace another fuel tank instantly to improve convenience.

A burner gun includes a case, an ignition device, a switch and a operational part. By the switch and an operation rail in the case, the ignition device can only be activated by correctly operating the switch and pulling the operational part. The ignition device cannot activated by pulling the operational part if the switch is not correctly operated, so that the ignition device is prevented from being activated unintentionally to reduce possibility of causing fire disasters.
