PROBLEM TO BE SOLVED: To obtain a heating furnace burner equipment in which the inside of the furnace including the neighbourhood of a gas discharge section can be heated evenly, and production of NOx can be suppressed. SOLUTION: There are provided as a gas supply section 50 a main gas supply section 5 and a sub gas supply section 51. On the main gas supply section 5 there is provided a main combustion burner 5a for supplying main combustion gas G1, and there is provided an auxiliary combustion burner 5b for supplying auxiliary combustion gas G2 and oxygen rich gas A1 for combusting the auxiliary combustion gas G2 to form an auxiliary flame 14, and for heating the main combustion gas G1. There is further provided a sub gas supply section 51 for injecting the combustion gas G into the furnace at an injection speed slower than the injection speed of the combustion gas from the main gas supply section 5. |
