Abstract:

To provide a compactly formable heating furnace capable of preventing an object to be heated from being heated locally.

Burners 31, 32 have gas nozzles 411, 421 for injecting fuel gas F and air nozzles 511, 521 for combustion for injecting air A for combustion and the gas nozzles 411, 421 and the air nozzles 511, 521 for combustion protrude from an inner wall 11 to a ring shape combustion space 13. The air nozzles 511, 521 for combustion are provided so that an injection direction of the air A for combustion crosses an injection direction of fuel gas F of the gas nozzles 411, 421. The heating furnace 1 is structured so that the air A for combustion injected from the air nozzles 511, 521 for combustion presses flame toward an inner wall 11 to prevent the flame generated by combustion of the fuel gas F and the air A for combustion from touching the object 2 to be heated.
