    • 专利摘要:
    A ceramic gas burner for a combustion chamber of a hot-blast stove of a blast furnace has parallel vertical supply ducts (1,2) for the two combustion components (gas and air). One duct (1) opens upwardly at a first outlet opening (3) which is rectangular in shape. The second duct (2) opens at second outlet openings (5) which are on each side of and above the first outlet opening (3) and whose outflow directions are oblique to that of the first outlet opening (3). Recesses (8) extend in each long side of the first opening (3) towards the second openings (5). To improve the mixing of the two components, opposite each recess (8) there is another such recess (8) in the other long side of the opening (3).

    专利说明:

    This invention relates to the combustion of gaseous fuel in burners of combustion chambers of air heaters, mainly used with blast furnaces.
    The purpose of the invention is to improve the quality of mixing of the combustion components.
    FIG. 1 shows schematically the head of a ceramic burner; FIG. 2 is a section A-A in FIG. one"
    The ceramic gas burner contains a burner head 1 with an upwardly directed outlet 2 and located in a horizontal plane, connected to a vertical gas supply pipe 3 on the periphery of which in the head 1 parallel to this pipe 3, air supply channels 4 are equipped with inclined outlet nozzles 5 the long sides of the rectangular outlet 2 are grooves 6 inclined towards the outlet nozzles 5 of the air supply ducts 4 located above the rectangular outlet hole 2. The grooves 6 on one long side of the outlet 2 are located opposite and coaxially with the corresponding kagava 6 of the other side of this hole 2. Each groove 6 can be located opposite each of its outlet nozzles 5 of channel 4, in addition, grooves 6 can be made a cross section extending along the course of the flows can be made with an upward expanding depth to form a channel of the diffuser profile. The head 1 is located in the combustion chamber 7.
    The burner works as follows.
    When the burner is operating, gas is supplied to the combustion chamber 7 through pipe 3, and air is supplied.

    Claims (4)
    [1]
    Claim
    1. Ceramic. Gas burner of the combustion chamber of the blast stove containing a burner gas. 15 artful with an upwardly directed and horizontally discharged outlet connected. to the vertical gas supply pipe, on the periphery of which in the head there are air channels parallel to this pipe, which have inclined outlet nozzles, and on the long sides of the rectangular outlet opening there are grooves inclined towards the outlet nozzles for air supply; above the specified rectangular outlet, is distinguished by the fact that, in order to improve the quality of mixing of the combustion components, the grooves on one long side of the outlet are located but also coaxially corresponding to the other side of this hole.
    [2]
    2. Burner on π. 1, characterized in that each groove is located opposite each of its exhaust nozzle channel for supplying air.
