ABSTRACT:
A method of combustion and a burner assembly wherein at least one fuel and at least one oxidizer are injected separately. The oxidizer comprises a primary oxidizer stream and a secondary oxidizer stream. The primary oxidizer stream is divided into at least two portions. One portion is injected close to the fuel whereby generating a first incomplete combustion. The second portion is injected downstream of the first injection point with the fuel source consisting of the remaining uncombusted fuel of the first incomplete combustion in addition to the fuel. The secondary oxidizer stream is injected downstream from the primary oxidizer stream, whereby resulting in combustion with the unreactive fuel gases remaining from the first combustion.
