Abstract
The object of the present invention is to provide a method for burning a burner which has NOx reduction effects and has practical value, and a device therefore; the present invention provide A method for burning a burner in a heating furnace including a step of: periodically changing at least one of a flow rate of a fuel fluid and a flow rate of an oxidizing agent fluid which are supplied to the burner while periodically changing an oxygen concentration in the oxidizing agent fluid, thereby an oxygen ratio which is calculated by dividing an amount of oxygen supplied by a theoretical necessary amount of oxygen is periodically changed, and the periodical change of the oxygen ratio is made different from the periodical change of the oxygen concentration to cause combustion in periodically vibrational conditions.
