A gas stove equipped with an anti-dry-burning device comprises the anti-dry-burning device and a gas cooker with a flameout protection device. The anti-dry-burning device is arranged at the central position of a combustor of the gas stove and is fixed on the gas stove. The anti-dry-burning device at least comprises a temperature controller, a temperature controller insulating base, a spring, an anti-dry-burning probe body and an anti-dry-burning probe base. The temperature controller is a bimetal thermostat, and is serially connected between an inductive probe of the gas cooker flameout protection device and a gas solenoid valve. The inductive probe of the gas cooker flameout protection device at least comprises a thermocouple and an ion sensor needle.

A rich-lean combustion apparatus includes a first plate and a second plate provided to face each other to allow a rich mixture to flow therebetween through a rich mixture passage, a third plate provided to allow a lean mixture to flow through a lean mixture passage formed between the second plate and the third plate, a first burner port member for combusting the rich mixture, and a second burner port member for combusting the lean mixture, wherein, between the first plate and the second plate, a mixture inlet into which some of air supplied from a ventilator and a fuel gas injected from a nozzle are introduced, a mixture passage introduction portion and a mixture passage diffuser for allowing the rich mixture flowed into through the mixture inlet to flow to the rich mixture passage, an air inlet into which the remaining of the air supplied from the ventilator is introduced, and an air passage introduction portion through which the air flowed into through the air inlet flows are formed, and wherein a plurality of air through-holes are formed to pass through the second plate to allow the air of the air passage introduction portion to be spouted into an air passage formed between the second plate and the third plate, and a plurality of distribution holes are formed to pass through the second plate to allow some of a mixture passing the mixture passage diffuser to be spouted into the lean mixture passage.

Systems and methods are disclosed that may include providing a wellhead gas burner to burn wellhead gas produced from a wellhead to heat water and/or other chemicals used in hydrocarbon production and/or well completion processes, including, but not limited to hydraulic fracturing (fracking). The wellhead gas burner may include a pressure regulator and an expansion chamber that permit the wellhead gas burner to continuously operate and accommodate wellhead gas pressure fluctuations. The wellhead gas burner may also be configured as a primary heat source and integrated with a traditional propane/diesel gas burner system configured as a supplemental heat source. The wellhead gas burner may also be mounted to a mobile superheater truck.

A burner device (190) comprising an air intake, a burner head (192) including an ignition device, a body section (196) defining a fluid flow channel between said air intake and said burner head (192), and a gas injector (205) for injecting combustible gas into said fluid flow channel. The burner head (192) is oriented such that its longitudinal axis is substantially perpendicular to the plane in which the channel is defined and in which fluid flows, in use, along said channel.

An adjustable fit for torch head includes a hollow ring or circular body; an elongated tube or stem. The fit for torch head in different sizes which easily attached to an existing torch head leading to a circular piece at the end of the tube that opens like a jaw.

An over or grill burner includes a hollow body with a supplying port receiving a gaseous fuel mixture and outlet holes emitting the gaseous fuel mixture, and a conveying duct conveying the gaseous fuel mixture toward the hollow body, which has a delivering port and a supplying/mixing port with a first aperture for a fuel gas and a second aperture for a gaseous combusting product, and a reflector conveying a flame produced by combustion of the fuel mixture from the outlet holes. The supplying port of the hollow body and the delivering port of the conveying duct have a substantially circular cross-section and are connected to each other in a freely rotatable manner.

An orifice holder includes a body that defines an inner chamber and inner wall portions. The inner wall portions each have a first width that is defined relative to the upper portion of the body. A first cup extends outwardly from the inner wall portions. A second cup extends outwardly from the inner wall portions and interconnects with the first cup through the inner wall portions. An airflow path is defined to the inner chamber from the first and second cups.

A burner base for a stacked burner assembly to secure a uniform distribution of gas flow. The burner base couples with a top burner cover and together define an internal gas mixture chamber. The burner base includes a barrier structure along a perimeter having a plurality of structural zones. A first structural zone includes a semi-circular barrier structure having a height that is taller at a middle portion than at the end portions. A second structural zone includes an arc structure having a height that is taller than the heights of adjacent structural zone heights. A third structural zone includes a semi-circular structure having a consistent height along the structure. A fourth structural zone includes a non-raised semi-circular structure. The barrier structure is configured to facilitate the distribution of the gas within the mixture chamber.

An orifice holder includes a body defining inner wall portions facing each other and spaced apart at a first distance for receiving a portion of a stem of a spreader therebetween. The body further defines a first cup and a second cup, each extending outwardly from opposing sides of the inner wall portions. Each of the first cup and the second cup has a peripheral rim extending around an upper perimeter thereof and open at respective adjacent ends of the inner wall portions to define a fluid path past the peripheral rims, through the respective first and second cups, between the inner wall portions, and into the stem.
