1. a kind of method for controlling combustion of continuous heat treating furnace, the continuous heat treating furnace is along the band advanced in heat-treatment furnaceThe direct of travel of steel is arranged side by side multiple radiant tube burners, and to the radiant tube burner fuel and combustion air are supplied,Fuel is set to burn in radiant tube burner, so as to be carried out continuously heat treatment to the strip advanced in heat-treatment furnace, its featureIt is,The combustion control device being respectively controlled to the burning in each radiant tube burner and stopping is set,Using the combustion control device, stop the burning in the radiant tube burner of part, and switching makes what burning stoppedRadiant tube burner,In the radiant tube burner for carrying out combustion event, to suppress NOxThe mode of generation reduces supplied combustion airAir, to be burnt, on the other hand, in the radiant tube burner that combustion event stops, supplying combustion air to remove than μ

  • Remove the flue dust produced in radiant tube burner.
