A spray-cool system disposed in the interior area. A burner tube at least partially disposed in the interior burner area and extends into the front surface. The burner tube is configured to accept a burner.

A multi-stage flame acceleration device and method for a gas-fuel engine are provided. The device includes a pressing piece, an upper chamber, a spark plug, a fuel ejector, a cooling device, and a flame acceleration nozzle. The spark plug and the fuel ejector are mounted in the upper chamber. The pressing piece is sleeved on an upper part of the upper chamber, and the device is wholly and fixedly connected to a cylinder head through a step groove of the upper chamber. A nozzle sealing ring, the flame acceleration nozzle, and a cylinder head sealing ring are mounted at a bottom of the upper chamber from top to bottom in sequence. Annular obstacles formed by annular plates are arranged in a chamber of the flame acceleration nozzle. In the method, a fuel is ejected in the chamber of the flame acceleration nozzle to obtain a homogeneous gas mixture.

A burner assembly includes a plurality of bumers for mixing fuel and air. Each of the plurality of burners includes: at least one fuel nozzle for injecting the fuel; and a mixing passage into which the fuel injected from the at least one fuel nozzle and the air are introduced. Each fuel nozzle includes a protruding portion protruding upstream of an inlet of the mixing passage in a flow direction of the air. Each fuel nozzle includes a fuel injection hole formed on a side surface of the protruding portion. At least a portion of a first air passage for flowing the air is formed inside the protruding portion. The first air passage includes: an inlet formed on a surface of the protruding portion on an upstream side of the fuel injection hole in the flow direction of the air; and an outlet formed on a side surface of the protruding portion or a passage wall of the mixing passage. At least a portion of the outlet is formed downstream of the fuel injection hole in the flow direction of the air.

A combustor nozzle, a combustor, and a gas turbine including the same are provided. The combustor nozzle includes a nozzle module. The nozzle module includes a central tube having an air flow path, through which air flows from a front-to-rear direction, and an opening hole at a rear end thereof, a shroud into which at least a part of the central tube is inserted, and having an air inlet at a front end thereof, wherein a mixing flow path is formed between the shroud and the central tube so that the air and injected fuel flow therethrough, and a plurality of cooling channels, each of the plurality of cooling channels extending rearward from an inlet communicating with the air flow path to an outlet communicating with the mixing flow path while passing through a sidewall portion of the central tube.

The present invention relates to a burner. At least one first passage, at least one second passage and a mixing chamber are formed in the burner, and the mixing chamber is respectively connected to an outlet of the first passage and an outlet of the second passage, so that a first fluid and a second fluid are mixed in the mixing chamber to form a fluid mixture; wherein the burner includes a nozzle, and at least one through passage fluidly connected to the mixing chamber is formed in the nozzle, so that the fluid mixture flows out from the at least one through passage, and wherein the sum of the sectional areas of the at least one through passage is smaller than the sectional area of the mixing chamber.

The present disclosure discloses a combustion chamber and a combustion apparatus. The combustion chamber includes: a first surrounding plate located on an outer side and a second surrounding plate located on an inner side. A combustion cavity is defined by the second surrounding plate. The first surrounding plate and the second surrounding plate are spaced apart from each other to define at least one air duct in communication with the combustion cavity. Each of the at least one air duct has an air inlet hole formed in the first surrounding plate, and an air outlet hole formed in the second surrounding plate.

A powder coated aluminum barbecue pit burner that burns gas in the same way that stainless steel burner tubes do, but last longer and do not rust. The use of powder coated aluminum makes the burner according to the present invention corrosion resistant. Additionally, the powder coated aluminum burner of the present invention also contain a heat sink element that prevents the temperature of the tubes from getting too high. Controlling temperature and using powder coated aluminum burners, instead of stainless steel, ensures that the burner will last longer. Another embodiment utilizes a water cooled system in connection with the heat sink element.

Embodiments provide a combustion structure that can achieve stable combustion by addressing the aforementioned drawbacks in the prior art such as low flame stability, backfire, deflagration, blockage and/or any other drawbacks. The combustion chamber structure in accordance with the disclosure can include: a grate structure including a first set of elongated components, a fire retention structure including a second set of elongated components. The first set of first elongated components can be arranged along an axial direction within the combustion chamber structure. The second set of elongated components can be arranged along the axial direction in a same direction as the first elongated components. The second set of elongated components can be configured to generate a negative pressure zone within the combustion chamber. The first set of elongated components can form apertures that can be aligned with apertures formed by the second set of elongated components.
