ABSTRACT:
The burner is constructed with three concentric annular spaces which terminate in a ceramic muffle and a plurality of straight passages which extend coaxially through the muffle. The innermost space surrounds a burner lance and is supplied with fresh air while the other annular spaces and passages are supplied with a flue gas/air mixture from a distribution chamber. This latter chamber is connected to a take-off line of the combustion chamber in order to receive the flue gas and various means can be used to mix fresh air into the flue gas before entry into the distribution chamber.
