Provided is a burner including a burner head configured to receive a mixed gas; and a burner cap configured to cover the burner head, wherein the burner head includes an outer wall having a plurality of first flame holes at which flame are generated, an inner wall spaced from the outer wall and having a plurality of second flame holes at which flame are generated, and a mixed gas chamber formed between the outer wall and the inner wall, and a staying guide provided at an inner circumferential surface of the inner wall and configured to allow the mixed gas flowing from the mixed gas chamber to be stayed thereon.

The present invention discloses a burner, a gas water heater and a processing method of fire row, wherein the burner comprising: a plurality of fire rows; an air channel is formed between at least two fire rows; the fire row has a burning substrate; the burning substrate is provided with main burning holes; the burning substrate is further provided with auxiliary burning holes downstream of the main burning holes; at least one the auxiliary burning hole is disposed on at least one side of the main burning hole in a length direction of the burning substrate; flame of the auxiliary burning hole intersect with flame of the main burning hole; and a frame for mounting the fire rows. The burner, the gas water heater and the processing method of the fire rows disclosed in the present invention can help to decrease flame height, facilitate manufacturing and reduce costs.

A burner includes a base and a combustion tray, wherein the base has an inlet pipe and two horn-shaped tubes. The horn-shaped tubes are connected to opposite sides of the inlet pipe, wherein each of the horn-shaped tubes respectively has a first section. A length of the first sections is no less than an inner diameter of the inlet pipe at where the horn-shaped tubes are connected to. The combustion tray is engaged with the base, and communicates with the horn-shaped tubes. Whereby, gas and air could be fully mixed while flowing through each of the first sections. The symmetrical horn-shaped tubes could direct the airflow to the combustion tray, where the airflow could be outputted from flame vents of the combustion tray, whereby to generate more even flame, and to enhance the heating efficiency.

The invention concerns a surface-combustion gas burner comprising a combustion grate consisting of a metal sheet pierced with a series of slots. This burner is remarkable in that said metal sheet comprises a series of deflectors made in one piece with said metal sheet and protruding on the outer face of same, each deflector extending longitudinally and laterally above the entire surface of a slot, and in that each deflector comprises a guide portion for guiding the gas flow and a junction portion joining to the metal sheet, said guide portion being spaced from the metal sheet in such a way as to provide therewith at least one lateral gas ejection port, said deflectors being disposed in pairs in such a way that the lateral gas ejection ports of same face each other.

A flame holder assembly includes a flame holder element and a flame shield element. The flame holder element has a first plurality of apertures extending through the flame holder element. The flame shield element has a second plurality of apertures extending through the flame shield element. Each of the second plurality of apertures has a lateral dimension that is no greater than a flame quenching distance. The flame shield element is positioned facing the flame holder element, and the flame holder assembly is configured such that fuel is supplied to the flame holder element via the second plurality of apertures of the flame shield element.

A burner combustion system comprising: a burner casing comprising a first inlet and a first outlet; a combustion substrate disposed in the burner casing, wherein the combustion substrate is porous, and wherein the burner casing first outlet is disposed on an exterior of the combustion substrate; an inlet conduit disposed in the burner casing, the conduit comprising a second inlet and second outlet, wherein the second inlet of the conduit is outside the burner casing, and, wherein the second outlet of the conduit is connected to the burner casing first inlet, and wherein the combustion substrate may have a flat shape and wherein the burner combustion system may further comprise a baffle.

A burner includes a diffuser wall delimiting an inner space in flow communication with an inlet passageway and forming a diffuser perforation for the gas mixture to pass from the inner space to an outer side of the diffuser wall where combustion occurs. A pilot chamber is formed in the inner space and delimited by a pilot portion of the diffuser wall, forming a pilot perforation, and by a pilot wall extended into the inner space. The pilot chamber forms pilot inlet openings supplying air/gas-air pre-mixture into the pilot chamber. A pilot gas opening supplies non-premixed fuel gas into the pilot chamber. A main chamber formed in the inner space is delimited by a diffuser wall main portion, forming a main perforation, and by the pilot wall. The main chamber delimits a main inner volume and is in flow communication with the inlet passageway to supply air/gas-air pre-mixture.

A combustion membrane (14, 14) for a gas burner (2) forms a multilayer panel (22) including a gas-permeable diffuser layer (24) of a porous or fibrous solid material other than metal sheet, the diffuser layer (24) forming a combustion surface (25) facing an outer side (17), a support layer (26) formed by a metal sheet (32), arranged on an inner side (23) with respect to the diffuser layer (24), opposite to the combustion surface (25), and connected to the diffuser layer. The metal sheet has a pattern (27) of passage openings (28), a local deviating layer (29), bordering the support layer (26). Diverter flaps (30) bent transversely out of the support layer (26) and delimited by cutting or tearing edges (42) of the support layer metal sheet (32), form guide surfaces (31) oblique to a direction (40) orthogonal to an extension plane (41) of the multilayer panel (22).

A gas burner membrane is provided. The gas burner membrane comprises a plurality of first layers, each first layer comprises at least one inlet formed therein for receiving a combustible gas mixture, and a plurality of second layers. Successive first layers are separated by a second layer, and at least one outlet is formed between successive first layers.
