PROBLEM TO BE SOLVED: To provide a top-combustion hot blast stove that has a simple structure and is capable of reducing pressure loss of fuel gas or combustion air supplied.;SOLUTION: The top-combustion hot blast stove 1 is equipped with: a mixing part 2 having therein a mixing chamber also serving as a burner; and a regenerator that is located below the mixing chamber and is communicated with the mixing chamber. In the periphery of the mixing part 2 a fuel gas branch pipe 8 and an air branch pipe 9 are disposed around the mixing part 2. A fuel-supplying pipe 10 and a plurality of fuel nozzle pipes 19 are connected to the fuel gas branch pipe 8, provided that the fuel nozzle pipes 19 are connected to the mixing part 2 for blowing the fuel gas into the mixing chamber. An air-supplying pipe 16 and a plurality of air nozzle pipes 20 are connected to the air branch pipe 9, provided that the air nozzle pipes 20 are connected to the mixing part 2 for blowing the combustion air into the mixing chamber.;COPYRIGHT: (C)2012,JPO&INPIT
