PURPOSE:To enable easy control of temperature distribution at the interior of a furnace, by a method wherein a plurality of burner guns are installed to change fuel distribution of each of the burner guns. CONSTITUTION:A fuel distribution computer 37 is energized by means of a fuel flow rate signal branched from a fuel control part 28 to set their respective openings of fuel distributing valves 38 so as to match a fuel flow rate according to the predetermined fuel distribution. The fuel distributing valves 38 are disposed corresponding to their respective burner branch pipes 24 of a multiburner 23. A fuel branching part 39 feeds out the fuel, fed from a fuel flow rate regulating part 31, to their respective fuel distributing valves 38. Namely, various quantities of the fuel proportioning their respective openings of the fuel distributing valve 38 are fed out to their respective branch pipes 24. This permits easy control of temperature distribution within the furnace. |
