COMBUSTION DEVICE FOR HEATING FURNACE

摘要

PROBLEM TO BE SOLVED: To provide a combustion device for a heating furnace, capable of simplifying installation work even while the entire heating object can be uniformly heated.SOLUTION: An oxygen-containing gas supply port 5 is formed in a laterally long shape on a furnace sidewall and is provided for supplying oxygen-containing gas for combustion in a flow state to be wider toward a combustion area above a heating object inside a heating furnace. A gas fuel jetting part W for jetting gas fuel to the combustion area is provided on a lower part of the oxygen-containing gas supply port 5 on the furnace sidewall. As the gas fuel jetting part W, a burner tile 8 with a plurality of fuel jetting ports 7 formed in a state of being dispersed over the entire width in a lateral width direction is installed on the furnace sidewall.
