摘要:
A fire hole part structure of a gas burner, which is constructed to be manufactured at a low cost, can improve flame stability, and can prevent incomplete combustion due to the length of flame. The structure is provided to a premixing ignition burner, which is installed to apply heat to a heat exchanger of a boiler, and includes fire hole pieces which are installed parallel to one another in mounting openings of a burner body, and each of which is defined with fire holes at regular intervals. An upper wall of at least one of the fire hole pieces is bent or curved to extend in at least two directions, and the fire holes are defined through respective surface portions of the upper wall, which extend in different directions, to face different directions.

A cooking device is provided. The cooking device includes a cavity and a burner. The cavity provides a cooking chamber. The burner is at the cooking chamber in the cavity and heats food in the cooking chamber. The burner includes a supply part and a combustion unit. A gaseous fuel mixed with air flows in the supply part. The combustion unit is connected to the supply part to receive the mixed gaseous fuel and to burn the received mixed gaseous fuel flowing within the combustion unit. The combustion unit has a single loop shape.

The present invention relates to a device for heating furnace installations (10) for articles, in particular for glassware. The furnace installation (10) in this case has at least one furnace space (11), in which the articles are located. Also provided is a burner (20), in which a gas/air mixture (21) is burned, whereby a hot, gaseous medium is produced. The hot medium can be conducted into the furnace space (11), which is thereby heated. Also provided is a fan (30), which provides the circulation of the air (14) in the furnace space (11). The burner (20) is formed here as a surface burner and is located inside the furnace space (11). Furthermore, the burner (20) is arranged in the vicinity of the fan (30) in such a way that the hot medium can be distributed by the fan (30) directly.

There is provided a burner structure used for a portable gas cooking stove, including a mixing tube (31) with an open end, a burner head (32) with an open bottom surface, and a top surface with at least one opening (32a), an inner cup (33) sized to be housed in the burner head (32), and having an open bottom, and a bottom plate (35) with a through-hole through which the mixing tube (31) is inserted, covering the open bottom of the burner head (32), characterized by that the inner cup (33) is installed inside the burner head (32) in such a manner that an inner surface of the inner cup (33) faces the mixing tube (31), and that the mixing tube (31) is installed on the bottom plate (35) so that the open end thereof is positioned higher than a bottom of the inner cup (33).
摘要:
A gas burner (1) for a heater comprises a planar metal frame portion (2) with an elongated opening (3) defined by two longitudinal edges (5) and by two transversal end edges (6), as well as a combustion membrane (7) in the form of a tridimensional shell, connected to the frame portion (2) along the longitudinal (5) and transversal (6) edges, wherein the combustion membrane (7) has a diffuser layer (8), which forms an outer combustion surface (9) made of a perforated metal sheet, and which extends between the two longitudinal edges (5) with a single curvature out of the plane of the frame portion (2), and two closure portions (11) made of metal sheet extending from the transversal edges (6) out of the plane of the frame portion (2) and which close end areas (12) between the diffuser layer (8) and the transversal edges (6) of the frame portion (2).
