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. 展开▼
