The disclosure relates to a burner having a container for storing liquid fuel, a fuel inlet for filling liquid fuel into the container, and a fire outlet for fire from burning liquid fuel to leave the burner. The fire outlet may function as fuel inlet or a separate fuel inlet is provided. The burner includes a stopping mechanism and an actuator for controlling the stopping mechanism. The stopping mechanism is displaced by the actuator towards a first position, when the temperature of the actuator is changed from a relatively high temperature to a relatively low temperature. The stopping mechanism is displaced by the actuator towards the second position, when the temperature of the actuator is changed from a relatively low temperature to a relatively high temperature. The disclosure also relates to a method of operating such a burner and a funnel for a burner.

A furnace includes a gas burner exposed to a heat-exchange tube. An inducer is fluidly coupled to the heat-exchange tube and configured to induce draft air through the heat-exchange tube. A regulator is fluidly coupled to the gas burner. A rollout shield is disposed adjacent to the gas burner. A rollout switch is disposed in the rollout shield. The rollout switch is electrically coupled to the regulator. At least one vent is formed through the rollout shield adjacent to the rollout switch. The vent provides a path for a rollout flame to the rollout switch. The at least one vent is disposed on at least two sides of the rollout switch.

A combustion air proving (CAP) system for a burner assembly having a burner for providing heated air to a location, a controller, and a back plate, where outside air is fed to the burner via a conduit. The CAP system is connected to an inlet of the system. An outlet of the system is connected to the burner via the back plate. A damper within the system is translatable between open and closed positions for allowing and blocking air flow, respectively. A sensor measures an air flow parameter of air flow to the burner. The sensor communicates with the controller, which shuts down the burner if the parameter measured by the sensor meets a predetermined threshold value. An assembly installer may test for proper sensor and controller functions by translating the damper to the closed position and blocking outside air flow.

An apparatus for producing a stabilizing base flame for a premix main burner flame in a burner assembly having a burner end, a first fuel line, a first fuel nozzle, a second fuel line, and a second fuel nozzle. The apparatus comprises a conduit having a first fuel line end in fluid communication with the first fuel line, a second fuel line end in fluid communication with the second fuel line, a valve in fluid communication with the conduit and a center fuel stabilization bluff body mounted in the burner end. The center fuel stabilization bluff body comprises a first ring, a second ring and a cylinder disposed between the first ring and the second ring.

A torch device having a pivoting torch arm, including a fuel delivery system having a fuel tank and microjet burners positioned in the end of the torch arm, and an ignition system including an ignition button and a piezoelectric igniter for igniting fuel, and an interlock mechanism including a mounting tab pivotally attaching the torch arm to the body of the torch, with a guide pocket defined by a laterally-extending wall of the mounting tab, and a rocker arm having a distal arm cooperating with and confined within the guide pocket, and a proximal arm cooperating with the ignition button, and configured to prevent a user from pressing the ignition button based on the angular position of the torch arm relative to the torch body.

A nozzle structure of a burner includes: a housing having an exhaust opening penetratingly-formed at an upper surface thereof, and having therein an accommodation space communicated with the exhaust opening; a fuel supply member connected to the housing such that one end thereof communicates with one side of the accommodation space, for supply of liquid fuel to inside of the accommodation space; a fuel supply controller accommodated in the accommodation space so as to be movable up and down, and having a fuel supply micro-control member at an end thereof, the fuel supply micro-control member configured to micro-control the amount of fuel to be supplied, by being selectively inserted into or separated from the exhaust opening as it moves up and down; and a heating pipe connected to two sides of an outer surface of the housing with different heights, so as to communicate with the accommodation space.

Assembly comprising, on a turbomachine:a combustion chamber (30) having a longitudinal axis (30a) and comprising: internal and external longitudinal walls (90) having a first opening (90a) substantially transverse to said axis (30a), an outer casing (110) having a second opening (110a) likewise substantially transverse to said axis (30a),a turbomachine sparkplug (150),a device (130) for radially securing the sparkplug (150), which device (130) comprises a sparkplug adapter (160) fixed toward a first end to the outer casing (110), facing the second opening (110a) and through which adapter and casing the sparkplug (150) in question passes, and a sparkplug guide (190) kept in contact with the external longitudinal wall (90), facing the first opening (90a) and through which the sparkplug (150) passes to emerge in the combustion chamber (30), the sparkplug (150) and the sparkplug guide (190) each having a screw thread (103, 105), the screw threads (103, 105) being screwed together so as to stabilize the sparkplug (150) radially to the axis (30a) of the combustion chamber (30) with respect to said external longitudinal wall (90), andin this condition, the sparkplug (150) and the sparkplug guide (190) are mounted freely with respect to the outer casing (110) in a direction substantially radial to the axis of the second opening (110a).

A pilot tube assembly for easy repair and/or replacement of a pilot hood is disclosed. In one example, a field configurable burner tube assembly may include a burner tube, a pilot hood, wherein the pilot hood engages the burner tube and can be secured to the burner tube in any of two or more different orientations in the field, a thermo-electric device, and a bracket for carrying the pilot hood and burner tube assembly adjacent to the thermoelectric device.

A gas combustor comprises a gas container, a fuel gas controlling device, a housing, a piezoelectric device and a combustion device. The safety switch is slidably disposed in an opening of the housing and includes a slide member, a fasten member and a passive member, adjacent surfaces of the slide member and the fasten member are disposed with a connecting mechanism and a radial sliding mechanism, thereby enabling the slide member to perform a radial sliding motion towards the left or the right at the front end of the fasten member; a rear surface of the passive member is formed with a lock tenon abutted against a block tenon of the fuel gas controlling device, thereby forming a lucked status; when the slide member is pulled towards the left or the right, the lock tenon is released from the block tenon, thereby forming an unlocked status.

A burner system comprises a reservoir configured to store fuel, a filler coupled to the reservoir and including a fill port, a burn chamber coupled to the reservoir; and a shutter including a fill cap and a snuffer. The shutter is movable between a burn position wherein the burn chamber is operable to burn fuel stored in the reservoir and a fuel position wherein the fill port is usable to fill the reservoir with fuel.
