A burner system configured to distribute gas evenly to multiple gas release nozzles shaped to generate increased flame height and a more aesthetically pleasing and consistent flame.

A heating torch (10) for burning a mixture of fuel and air. The heating torch (10) includes a fuel inlet port (12) for supplying fuel from a fuel source to an air entrainment chamber (14). The air entrainment chamber (14) includes at least one air inlet (22) for supplying air from the atmosphere to the air entrainment chamber (14). The air entrainment chamber 14 includes an outlet (26) for discharging from the air entrainment chamber (14) a mixture of fuel and air in a flow path extending from the outlet (26). The heating torch (10) also includes a combustion chamber (28) provided in the flow path A and spaced from the outlet (26). The combustion chamber (28) has an open end (30) facing in a generally downstream direction away from the outlet (26). The combustion chamber (28) includes at least one side opening (36) extending along a side of the combustion chamber (28).

The present disclosure provides a nozzle structure for a hydrogen gas burner apparatus, capable of reducing an amount of generated NOx. A nozzle structure for a hydrogen gas burner apparatus, includes an outer pipe, an inner pipe disposed concentrically with the outer pipe, and a stabilizer configured to throttle a space between the outer pipe and the inner pipe. The inner pipe includes an inner pipe end part with an axial opening hole and a circumferential opening hole formed therein, the axial opening hole penetrating in an axial direction of the inner pipe, the circumferential opening hole penetrating in a radial direction of the inner pipe. A hydrogen gas flows through the inner pipe. The circumferential opening hole lets the hydrogen gas flow out from the inner pipe in the radial direction of the inner pipe.

A gas premix burner and a gas water heater. The gas premix burner has a combustion direction, the gas premix burner can be matched and connected with a premix chamber that is disposed upstream the combustion direction of the gas premix burner, gas and air can be burned by the gas premix burner after mixed in the premix chamber; the gas premix burner comprising: a burner substrate, a main combustion hole provided on the burner substrate; an auxiliary combustion hole disposed downstream the main combustion hole along the combustion direction on the burner substrate; an auxiliary flame of the auxiliary combustion hole intersects a main flame of the main combustion hole. The present application provides the main combustion hole upstream the auxiliary combustion hole along the combustion direction, since the main flame is usually larger in scale than the auxiliary flame, by providing the main flame upstream the auxiliary flame, it will be easier for the auxiliary flame and the main flame to intersect each other, and then the effect of stabilizing the flame is realized by opposed flames formed by the auxiliary flame and the main flame.

A burner has: a combustion plate part for ejecting air-fuel mixture; and a flame rod which lies opposite to a portion of the combustion plate part which has a picture-frame-like burner frame; a metal-fiber knit which covers an opening enclosed by the burner frame; and a distribution plate which has formed therein distribution holes and which sandwiches the metal-fiber knit between the burner frame and the distribution plate through the distribution holes and the metal-fiber knit. The flame rod has: a rod base part which lies opposite to a portion of opening peripheral part of the burner frame which is positioned on the same surface level as the opening; and a rod main body part which lies opposite to a portion of the metal-fiber knit. The distance between the rod base part and the opening peripheral part is made smaller than the distance between the rod main body part and the metal-fiber knit.

A water heater includes a water tank having an inlet and an outlet, and a flue extending through the tank. A nozzle is positioned near a first end of the flue, arranged so as to emit a fuel stream into the flue, and a flame holder is located within the flue in a position to receive the fuel stream and to hold a flame entirely within the flue.

An inlet assembly for a burner and a method are disclosed. The inlet assembly comprises: an inlet nozzle defining an inlet aperture coupleable with an inlet conduit providing an effluent gas stream for treatment by the burner, a non-circular outlet aperture, and a nozzle bore extending along a longitudinal axis between the inlet aperture and the outlet aperture for conveying the effluent gas stream from the inlet aperture to the outlet aperture for delivery to the combustion chamber of the burner, the nozzle bore having an inlet portion extending from the inlet aperture and an outlet portion extending to the non-circular outlet aperture. In this way, the non-circular outlet aperture provides a non-circular effluent gas stream flow into the combustion chamber. The non-circular effluent gas flow enables a greater volume of effluent gas stream to be introduced into the combustion chamber whilst still achieving or exceeding the required levels of abatement. This is because a non-circular effluent gas stream provides a reduced distance along which diffusion and reaction needs to occur compared to that of an equivalent circular effluent gas stream. Hence, an increased volume of effluent gas stream can be abated, compared to that of an equivalent circular effluent gas stream.

An improved combustion system in a combustion turbine engine is provided. The combustor system may include an injector assembly disposed in a combustion stage disposed downstream from a main combustion stage of the combustor system. The injector assembly may include a reactant-guiding structure arranged to deliver to the combustion stage respective jets of reactants through an array of ejection orifices disposed on one or more side walls of the reactant-guiding structure. The reactant-guiding structure may be configured to form a stream-lined body relative to a flow of a fluid to be mixed with the jets of reactants delivered to the combustion stage. The ejection orifices of the array may be aerodynamically-shaped to define a respective stream-lined orifice cross-section, (e.g., airfoil shaped).

Systems and methods are disclosed that include providing a cooking system that comprises a burner assembly and a heat exchanger, the burner assembly having a high velocity burner configured to provide the necessary high velocity, volumetric flowrate through the heat exchanger, and the burner assembly also having a low velocity burner configured to significantly reduce and/or substantially eliminate lift off that could result from operation of only the high velocity burner.

A heat gun includes a head portion. The head portion defines a flow passage having an inlet end at one end and an outlet end at another opposite end, and includes an inlet portion, an outlet portion and a flow guiding portion disposed between the inlet and outlet ends. The outlet portion is formed with two long sides and two short sides. The flow guiding portion is disposed between the inlet and outlet portions. The flow passage includes two flow guiding protrusions disposed at the flow guiding portion. The two flow guiding protrusions are disposed oppositely and extend oppositely along the long sides.
