Abstract

A method and apparatus for combustion of fuel in a combustion chamber with a hydraulic diameter D. Fuel and a primary oxidant are introduced via a burner lance into the combustion chamber, having a certain mean velocity u1 at entry, and a secondary oxidant with a mean velocity of u2 is introduced into the combustion chamber. The burner lance has a position p that has a distance Id1I defined as the smallest distance between p and a combustion chamber centerline.
