摘要

The system has a pilot burner (1) including a primary tube (2) opened at its downstream end (2a) and including a first conveying line (4) for conveying combustible gas in the primary tube. The burner has a secondary tube (3) opened at its downstream end (3a), where the secondary tube includes a second conveying line (6) for conveying oxygen-rich gas in the secondary tube. The burner has a third conveying line (5) supplying air to the primary tube. An ignition spark (7c) is arranged for ignition of the burner. The primary tube is partially located at inside of the secondary tube. Independent claims are also included for the following: (1) a combustion installation comprising an air separation unit for delivering oxygen-rich gas (2) a method for combustion of fuel.
