Abstract
The present invention relates to a combustion method for reducing the emission of nitrogen oxides. More particularly, the quick mixing of the air and fuel in the early stage of combustion is suppressed by setting the direction of fuel injection at an angle to the direction of the air stream axis and a position of a burner, in a preferable range resulting in the consequent effective use of a combustion exhaust gas, thereby minimizing the emission of nitrogen oxides to a great extent.
