    摘要: There is provided a top-firing hot blast stove capable of enhancing combustion efficiency in burner system, supplying high-temperature combustion gas to an entire checker chamber, and suppressing damage on a refractory material on an inner wall of a burner duct.
    A top-firing hot blast stove 10 has a burner system including: a burner 1 for passing fuel gas or combustion air to each of three or more pipe lines in a multiple pipe line structure; and a burner duct 2. A core pipe line 1b and a central pipe line 1c include a swirling flow generating means provided for generating a swirling flow of the fuel gas or the combustion air, while an outermost pipe line 1d carries a linear flow of the fuel gas or the combustion air, so that combustion gas HG including a linear component HG" and a swirling component HG' is generated in the burner duct 2. The combustion gas HG is supplied to a combustion chamber 3 from at least one or more of the burner systems in an inflow direction which does not pass through a center position of the combustion chamber 3.

    摘要: In order to overcome the problems that earlier methods and apparatus have experienced, in particular in order to provide for a method and burner producing NOx lower than 850 mg/Nm 3 at eight percent O 2 with adjustable flame shape and with higher heat transfer, it is proposed to provide oxygen enriched fuel into a combustion atmosphere (70) of a furnace (60), comprising:
    - injecting a fuel stream (32, 132, 232, 332, 432, 532) into the combustion atmosphere (70); and
    - providing, in particular injecting, oxygen (17, 117, 217, 317, 417, 517) into the fuel stream (32, 132, 232, 332, 432, 532) during the injecting of the fuel stream (32, 132, 232, 332, 432, 532) into the combustion atmosphere (70).
