BURNER EQUIPMENT FOR HEATING FURNACE

摘要

PROBLEM TO BE SOLVED: To provide a burner equipment for a heating furnace that can lower the concentration of NOx in combustion exhaust gas in the burner equipment for the heating furnace, which has a fuel feed part for feeding fuel inside the furnace and an oxygen-containing gases feed part for feeding the oxygen- containing gases for combustion inside the furnace separately to perform premixed combustion of the fuel and the oxygen-containing gases for combustion in the fuel feed part side inside the furnace. SOLUTION: A fuel feed part 5 is provided with a burner for combustion 51 having a fuel discharge hole 15 from which fuel G is discharged inside a furnace, and is provided with an exhaust gas flow path 16 having an exhaust gas discharge hole 17 from which combustion exhaust gas(g) that is produced by the combustion of the fuel is discharged inside the furnace from the outer periphery of the fuel discharge hole 15.
