A system for use with a fired vessel of production/separators or dehydration equipment that includes a metal box, a main burner, a pilot burner, and a flame arrestor. The main burner and the pilot burner extend through the metal box and the first flame arrestor is connected to the metal box.

A flame out candle system and method for automatically retracting and extinguishing a wick flame. The system includes a candle, a wick, and a puck assembly. The candle includes a bore to receive the wick, and a cavity to receive the puck assembly. The puck assembly can include a motor driven power screw or spur gears associated with spaced apart pinion gears. The puck assembly is removable from the candle for reuse in another candle. A wick engaging member can be operatively associated with the power screw for linear movement that is transferred to the wick. The pinion gears can be engageable with a rack gear positioned therebetween so rotation of the pinion gears translates into linear motion of the wick. A computer system can be utilized to control the motor based on a time signal, an activation signal, a sensor signal or any wireless signal.

A blowtorch includes a casing and a control unit. The control unit includes an activate button and a lock button. The lock button is switchable between a first lock position and an intermediate position, or between the intermediate position and a second lock position. The activate button is switchable between a standby position and an activation position when the lock button is in the intermediate position. The lock button contacts the activate button and restricts the activate button to hold in the activation position when the activate button is in the activation position and the lock button is in the first lock position or the second lock position.

A gas combustor includes: a housing, a storage cylinder, a fuel gas controlling device, an igniting device, a safety switch, and a combusting device. The safety switch has a fastening unit and a locking unit abutted against a locking bolt formed on a bottom surface of a press button; the fastening unit has an accommodation chamber allowing the locking unit to be accommodated, and a swing arm having a latching hook and longitudinally disposed at a front end of the accommodation chamber; the locking unit has a main body accommodated in the accommodation chamber, a longitudinal spring is disposed between the main body and the accommodation chamber, and the main body has a push button protruded from a penetrated slot longitudinally formed on a rear wall of the accommodation chamber, and a locking hook protruded towards the latching hook.

A system for use with a fired vessel of production/separators or dehydration equipment that includes a metal box, a main burner, a pilot burner, and a flame arrestor. The main burner and the pilot burner are within the metal box and the first flame arrestor is connected to the metal box.

A fuel nozzle including a plurality of fuel lines is provided, which has low thermal stress caused by a temperature difference between fuel and combustion air which are passed through the fuel nozzle, and also a gas turbine combustor using the fuel nozzle is provided. The fuel nozzle includes a plurality of channels including a first channel through which either fuel or combustion air is passed, and a second channel through which either fuel or combustion air is passed and which is distinct from the first channel. Of components of the fuel nozzle, a single-piece component makes up at least a region where the first channel and the second channel are placed.

A system for use with a fired vessel of production/separators or dehydration equipment that includes a metal box, a main burner, a pilot burner, and a flame arrestor. The main burner and the pilot burner are within the metal box and the first flame arrestor is connected to the metal box.

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 polymeric protective cover for a torch includes a thermal insulation surface layer for isolating the heat emitted, to protect a user from burns, and such protection for any belonging that may come into contact with the torch. The polymeric cover includes any or all of the following: (i) an open end, (ii) a closed end, (iii) an optional flexible strap, and (iv) a plurality of ridges on the inside and outside surface area. The heat and fire-resistant cover is shaped to fit securely on the torch barrel immediately after use of the tool so that its user may use it as a transportable, light-weight cover which may be used with the strap that circumvents the torch and secures to the polymeric cover. The aforementioned strap may also be attached to securely hold the torch barrel upright at various angles while in use by its user.

A downhole torch system and method of use includes a cylindrical housing, a protective material provided on at least one of the cylindrical housing and the fuel load, and a fuel load located within the cylindrical housing. The protective material is provided between the fuel load and the cylindrical housing to protect the cylindrical housing from adverse effects caused by the reaction of the burning fuel and/or the subsequent production of combustion products for cutting and/or perforating processes during operation of the torch system. The protective material significantly improves the cutting and/or perforating performance of the torch system.
