Classification: CPC F  Y | IPC F

Claim 0:
1. A regenerative burner comprising: a combustion chamber; a heat exchange chamber; and a communication passage between the combustion chamber and the heat exchange chamber,
wherein the combustion chamber comprises a tip of a fuel nozzle and a flame ejection port, and the combustion chamber is configured such that fuel introduced from the fuel nozzle into the combustion chamber can be burned in the combustion chamber using combustion air introduced into the combustion chamber through the communication passage to produce a flame within the combustion chamber before the flame is ejected from the flame ejection port;
wherein the fuel nozzle is configured such that a total amount of fuel burned in the regenerative burner is introduced into the combustion chamber;
wherein the heat exchange chamber comprises: an air port provided on a wall of the heat exchange chamber such that the air port is perpendicular to a port of the communication passage on a combustion chamber side, and a heat accumulator interposed between the communication passage and the air port, and the heat exchange chamber is configured such that combustion air introduced from the air port into the heat exchange chamber can pass through a space filled with the heat accumulator and then be introduced into the combustion chamber through the communication passage, and such that an exhaust gas introduced into the heat exchange chamber through the communication passage can pass through the space filled with the heat accumulator and then be discharged from the air port; and
wherein a port of the communication passage on the combustion chamber side is disposed on a surface of the combustion chamber perpendicular to a surface of the combustion chamber on which the fuel nozzle is disposed.
