Zusammenfassung:	PROBLEM TO BE SOLVED: To improve heating efficiency and reduce NOx in a combustion device for a hating furnace. SOLUTION: In the combustion device for the heating furnace, a long fuel jetting body B with a port 11 jetting fuel gas into the furnace provided in a tip side is provided to protrude into an oxygen-containing gas supply passage 6 in an attitude crossing a longitudinal direction of the oxygen-containing gas supply passage 6 supplying oxygen-containing gas for combustion into the furnace. A plurality of ports 11 are provided to be used as the port 11 in the same positions or substantially the same positions in a longitudinal direction of the fuel jetting body B in states aligned at intervals in a lateral width direction of the fuel jetting body B as seen from the longitudinal direction of the oxygen-containing gas supply passage 6.
