Method for controlling flame shape in burner for steel heating furnace


PURPOSE: To uniformly heat a material to be heated by making flame shape in a burner for a heating furnace constant regardless of the combustion load. CONSTITUTION: A combustion air nozzle at the inside of a fuel gas nozzle in the burner S.B. for the heating furnace and flow rate controllers 3, 4, a combustion air nozzle at the outside of the fuel gas nozzle and flow rate control devices 21, 24 are disposed and the ratio of the combustion air rates on the inside and the outside is controlled. Therefore, the uniform heating of the material to be heated can be attained. COPYRIGHT: (C)1992,JPO&Japio
