Abstract
A burner () which is useful for operating a heat generator includes a first upstream swirl generator () capable of swirling a combustion air stream, a device for injecting at least one fuel into the combustion air stream from the upstream swirl generator (), an exit ring () located at the downstream end of the burner () at the edge to the combustion chamber () where the fuel is burnt, and preferentially a mixing section () downstream from the upstream swirl generator () having a downstream end, having at least one transfer duct () for transferring downstream a flow of combustion air and fuel formed in the upstream swirl generator (), and having a mixing tube () downstream from the at least one transfer duct () and receiving flow from the at least one transfer duct (), wherein the downstream end of the mixing section borders the combustion chamber () and is formed by the exit ring (). Pilot mode operation of such a burner () is advantageously and economically made possible by providing a pilot burner system () in the exit ring () for injecting liquid fuel () into the combustion chamber ().
