A method of minimizing damage to a tip of an igniter in a combustor of a gas turbine engine includes mounting the igniter to a liner of the combustor downstream of the fuel nozzles using a floating collar, and directing pressurized air from a plenum surrounding the combustor through a plurality of purge openings and into an annular cavity surrounding the tip of the igniter. The purge openings are located in one or both of the igniter and the floating collar, and create cooling purge air jets into the annular cavity. The purge openings are formed within an arc that is disposed upstream of a bisecting plane extending along an igniter axis to a chamber axis of the combustor, such that the igniter axis lies in the bisecting plane. The igniter is free from the purge openings downstream of the bisecting plane relative to the stream of hot gases.

A cooking device is provided. The cooking device includes a frame that forms a cooking chamber; a burner provided inside the frame and having a plurality of gas outlet holes; an ignition unit provided inside the frame to ignite a mixed gas discharged from at least one of the plurality of gas outlet holes; and a fixing device to affix a position of the ignition unit with respect to the burner.

A gas heating device includes a main body defining a combustion chamber, a catalyst disposed in the combustion chamber, and an electric thermal device providing electric thermal energy to heat the catalyst and disposed in the combustion chamber and adjacent to a side of the catalyst.

In a fuel and oxidant combustion system, a flame holder support structure includes a heating element that receives electrical energy from an electrical power source. The heating element is raised to an auto-ignition temperature of a fuel and oxidant mixture directed, along an axis proximate the flame holder support structure, to a flame holder for combustion thereof.

A fresh-air intake according to aspects of the disclosure includes an outer cover having a pair of side panels disposed in a generally parallel spaced relationship, a top panel coupled to, and disposed generally perpendicular to, each panel of the pair of side panels, a bottom panel disposed generally parallel to the top panel, and a front panel coupled to, and disposed generally perpendicular to, each panel of the pair of side panels and the top panel, the front panel having a window formed therein, a supply line coupled to the bottom panel, a weir extending above the bottom panel and surrounding a junction with the supply line, a baffle disposed inside the outer cover, the baffle being disposed inwardly of the window so as to prevent infiltration of moisture into the supply line, and a weep hole formed in the bottom panel.

Sparkless igniters comprising a hot surface igniter assembly and a nozzle that produce a flame plume with diameter substantially similar to the diameter of the fire tube, and flame length less than the length of each leg of the U-shaped fire tube in heater treaters are disclosed. The disclosed igniters and methods are applicable to both vertical and horizontal heater treaters and improve the durability of fire tubes while reducing igniter fuel consumption by at least 30%.

A blow torch includes a casing, an igniter received within the interior, and a safety control device for preventing the actuator being operated from an unactuated position to an actuated position movably coupled to the casing and connected to the igniter. The safety control device includes an actuator movably coupled to the casing, a release movably coupled to the actuator, a first biasing member positioned between the actuator and the release, a retainer movably coupled to the actuator, and a second biasing member positioned between the actuator and the retainer.

An apparatus and method for reclaiming uncondensed hydrocarbons normally exhausted to the atmosphere from a still column of a glycol dehydrator system, and combusting the uncondensed hydrocarbons in a burner assembly of a reboiler after the burner assembly has been ignited by fuel gas.

A combustion system includes an electrically actuated flame location control mechanism.

Provided is a torch including a body having a first portion and a second portion angled relative to the first portion, a control knob at a top of the second portion for adjusting a flow of fuel through the torch, a trigger at a top of the first portion that is movable from an off position to an on position to at actuate an igniter, and a burn tube extending from an end of the second portion away from the first and second portions.
