Abstract
The burner has at least two fuel-carrying tubes which are arranged in parallel, the distance between adjacent fuel-carrying tubes being 5 to 30 cm. Each fuel-carrying tube is surrounded by a steam-carrying tube, which at its orifice end has a supply line for oxygen-containing gas. The steam-carrying tubes are surrounded by a common first cooling chamber through which cooling liquid is passed, the first cooling chamber constituting an annular chamber and extending into the area of the orifice ends of the steam-carrying tubes. Coaxial to the first cooling chamber a common second cooling chamber preferably is provided, which is surrounded by the first cooling chamber.
