Swirl-stabilised burner having an inertisation front and related methods

A method for combusting a combustion medium in which a fuel medium, an oxidation medium, and a process medium having inerting properties are supplied to a burner of a downstream combustion chamber such that a stabilised flame is formed in the combustion chamber, the method comprising:

• swirling the process medium in a passage with a swirl generator about a swirl axis in a flow direction;
• providing one or more partial mass flows to the passage through one or more openings in the passage;
• mixing the one or more partial mass flows in the process medium to produce a combustion medium;
• combusting the combustion medium downstream a front distance from the openings;
• and
• establishing an inertisation front displacing a flame the front distance from the openings in the flow direction.

A burner for making a combustion product in order to supply to a combustion chamber downstream of the burner a fuel medium, an oxidation medium, and a process medium having inerting properties such that a swirl-stabilised flame having an inertisation front is formed in the combustion chamber, the burner comprising:

• at least one swirl generator configured to swirl the process medium about a swirl axis extending in a flow direction;
• an inlet device having at least a first passage and a second passage in fluid communication with the at least swirl generator;
• and
• a plurality of openings downstream in the flow direction from the at least one swirl generator, the plurality of openings configured to provide one or more partial mass flows including at least the fuel medium and the oxidation medium to the passage of the inlet device.
