Combustion control unit and method for uniform heat storage in a regenerator of regenerative reheating furnace

摘要

The present invention relates to a heating furnace for heating a material to be heated, and the thermocouples 20 and 21 are installed in the upper and lower spaces of the heating furnace 1, respectively, and the thermocouples 20 and 21. Is connected to an input terminal of the distribution controller 22 (DCS), and a differential pressure gauge (G _{P1 to} G _P4 ) is connected to each of the fuel flow control valves (V _{A1 to} V _A4 ) to the output terminal of the distribution controller 22 (DCS). Each of the differential pressure gauges G _{P1 to} G _{P4 is} connected to each of the air flow control valves V _{B1 to} V _B4 , and each of the differential pressure gauges G _{P1 to} G _{P4 is} connected to each of the switching valves V _{5 to} V ₈ . In the heat storage combustion apparatus employed in the heating furnace, which is formed by connecting each of the right burners 3, 2, left burners 9, and 8 through the heating chamber, physically generated upper and lower temperature differences occur in the furnace. Problems such as deviation of heat storage amount of each heat storage device, deviation of supply temperature of combustion air, and nonuniform heating of material. The advantage is that you can.
