A fuel injection device for injecting an air-fuel mixture to a combustion chamber in a combustor of a gas turbine engine includes a fuel injector which is arranged on an axis of the fuel injection device. The fuel injector includes a fuel injection portion for injecting fuel in the radial direction of the fuel injection device, a fuel flow path portion forming a passage through which fuel is supplied to the fuel injection portion, and a heat shield cover that covers an end portion facing toward the combustion chamber side of the fuel injection portion such that an air layer is formed between the heat shield cover and the end portion.

The invention relates to an evaporator burner (1; 101) for a mobile heating device, comprising: a combustion chamber (3), a fuel feed line (4) for feeding liquid fuel, and an evaporator for evaporating fed fuel. The evaporator has a support body (6; 106) made of a nonporous material, comprising a fuel preparation surface (6a; 106a) which faces the combustion chamber (3) and which comes into contact with the liquid fuel. A surface structuring (11) with a plurality of depressions (11a) and elevations (11b) is introduced into the fuel preparation surface (6a; 106a) and/or into a support body (6; 106) rear face (6b; 106b) facing away from the fuel preparation surface.

A well test burner system has a plurality of burner nozzles supported by a support structure. Each burner nozzle has an air inlet, a well product inlet and an air/well product mixture outlet. At least one of the burner nozzles is supported to pivot relative to the support structure while the burner nozzle is operating to expel air/well product mixture.

An injector of a propellant combustion member, the injector including a first feed and a second feed; the first feed being connected to a plurality of feed chimneys arranged around a longitudinal axis; the second feed being configured so as to feed an injection chamber; and the injection chamber being connected to a plurality of feed sheaths with injection orifices, each feed chimney being surrounded by a coaxial feed sheath; the injector including a takeoff chamber connected to a takeoff duct for taking off the second propellant, the takeoff chamber being arranged in such a manner as to take off the second liquid propellant from the injection chamber; and it is configured to achieve uniform injection of the second propellant via the injection orifices.

A smudge pot with a pot, a pot lid, a chimney, a return pipe, and an access port. The pot has an interior configured to hold liquid fuel. The pot lid has a combustion hole and a return hole extending therethrough. The chimney is aligned with the combustion hole. The return pipe has a first end positioned inside of the chimney, a second end coupled with the pot lid at the return hole, and a pipe wall extending between the first end and the second end. The first end has a first opening aligned with a center of the return pipe and the second end has a second opening aligned with the center of the return pipe. The pipe wall comprises an arc adjacent to the first end and may be parallel to the chimney adjacent to the second end.

A torch canister with a fuel reservoir has a neck extending from the top of the fuel reservoir defining a wick holder. The torch canister has a flame guard affixed to the neck.

A burner includes an atomizing chamber, a flame tube in front of the atomizing chamber adapted to direct combusting fuel introduced by the atomizing chamber along an interior of the flame tube, and a controller. The controller is programmed to independently control rate of fuel flow to the atomizing chamber, rate of atomizing air flow to the atomizing chamber, and rate of combustion air to the flame tub. The controller is also programmed to perform operations including regulating, based on output of a gas sensor, at least the rate of combustion air to the flame tube to substantially maintain a first predetermined amount of excess air in the flame tube.

A method for turning an atomizing burner from an ON state to an OFF state is provided. The burner has independently controllable flows of atomizing air, combustion air, and fuel flow, the burner in the ON state having flow values of burner parameters including flow of atomizing air, flow of combustion air, and fuel flow. The method includes: changing, in response to an OFF instruction, flow of at least one of the flow of atomizing air, combustion air and/or fuel to a lower non-zero value; first discontinuing, after a first period of time since the changing, flow of fuel and flow of atomizing air; maintaining, for a second period of time since the first period of time, flow of combustion air; second discontinuing, after the maintaining, flow of combustion air; wherein the maintaining prevents buildup of excess heat inside the burner during the transition to the OFF state.

The invention relates to particular burners, and e.g. to a burner comprising a central main fuel lance, a pilot fuel conduit, a main oxidant conduit, an auxiliary oxidant conduit, and optionally a secondary fuel conduit, which are arranged in a particular and advantageous way to surround each other at least in their downstream sections. The invention further relates to furnaces including the burners and methods of operating the burners. Among others, the burners of the present invention allow a particularly advantageous way of including a pilot burner as an integral part of the main burner to ignite liquid fuel flame in a cold furnace. If required, the pilot flame can assist in extending the flammability limit or operating range of the liquid fuel burner.

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.
