Abstract
A self recuperative burner which can be fired with oil or gaseous fuel or both. The oil feed pipe is surrounded by a passage through which compressed air or fuel gas is conveyed to the burner head in such a way that it reduces the tendency for the oil to overheat. Additional cooling means are provided for the oil feed pipe. The burner has a burner head which is supported by a tubular part carried by a common wall between the combustion air supply passage and the combustion products exhaust passage, there being a sliding joint between the burner head and the tubular part which provides a circumferential series of arcuate gaps around the periphery of the burner head for the flow of combustion air between the burner head and the tubular part. The burner has an exhaust flue which is surrounded by a tubular part in which the combustion air inlet port is formed, the flue being cooled by incoming combustion air.
