Abstract

Disclosed is a method for combusting a fuel, the method comprising providing an oxidizer mass flow, providing a first oxidizer partial mass flow (101), combusting a fuel (102) in the first oxidizer partial mass flow thus providing a mass flow of combustion products (103), providing the mass flow of combustion products to a duct (14), and ducting the mass flow of combustion products through said duct in a flow direction. The method further comprises discharging a mass flow of a first supplementary fluid (104) into said duct, and discharging the mass flow of the first supplementary fluid in a discharge direction essentially aligned with the flow direction such as to provide a flow of the first supplementary fluid (104) essentially aligned with the flow of combustion products (103). The first supplementary fluid is selectively provided as one of an oxidizer and a premixed fuel/oxidizer mixture. In an embodiment the method comprises further discharging at least one further mass flow of a further supplementary fluid (105, 106) into the duct, wherein the further supplementary fluid is selectively provided as one of an oxidizer and a premixed fuel/oxidizer mixture, and discharging the at least one further mass flow (105, 106) essentially aligned with the flow direction. The at least one further mass flow (105, 106) is discharged laterally offset with respect to the discharged mass flow of first supplementary fluid (104) and across the flow cross section of the duct, such as to provide the mass flows of supplementary fluids as laterally stratified layers (114, 115, 116) of the respective supplementary fluids.
