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.摘要翻译： 提供了一种能够提高燃烧器系统的燃烧效率，向整个检验室供给高温燃烧气体并抑制对燃烧器管道的内壁上的耐火材料的损害的顶烧式热风炉。 顶烧式热风炉10具有燃烧器系统，该燃烧器系统包括：燃烧器1，用于使多个管道结构中的三条或更多条管线中的每一条通过燃料气体或燃烧空气; 核心管线1b和中心管线1c包括用于产生燃料气体或燃烧空气的回旋流的旋流生成装置，而最外管线1d承载着线性流 燃料气体或燃烧空气，使得在燃烧器管道2中产生包括线性部件HG“和旋转部件HG'的燃烧气体HG。燃烧气体HG从至少一个或多个 燃烧器系统处于不通过燃烧室3的中心位置的流入方向。
