Gas burner for reheat for heating steel industry products

机译:燃气加热炉,用于加热钢铁工业产品

摘要

The invention relates to a gas burner, in particular for a furnace for reheating iron and steel products, comprising a central channel (3) of supply of combustible gas, an annular channel 4 for feeding air, concentric, and a nose burner (7), inserted in a housing (9), cylindrical, formed in the internal coating of the roof of the furnace. & br / the nose burner comprises: & br / - a first series of orifices (10) for the passage of the gas, arranged in a circle on a ring having a mean diameter d1 and in communication with the central channel (3), the orifices (10) for the passage of the gas being coaxial with the axial direction (x) of the snout (7) of the burner, & br / - a second series of orifices (12) for the passage of air, arranged in a circle on a ring having a mean diameter d2 around the orifices (10) of the passage of gas, and in communication with the annular channel (4) for feeding air, the orifices (12) for the passage of air being oriented in a helix in order to create a turbulent air flow which causes a depression which draws in the gas.
