Abstract

A tubular combustion chamber including a tubular combustion chamber whose front-end is open; and, fuel-gas spraying nozzles and oxygen-containing-gas spraying nozzles, for spraying a fuel and an oxygen-containing-gas separately and individually, or for spraying a premixed gas; wherein respective orifices of the respective nozzles face toward an inner surface of the combustion chamber, so as to spray the fuel-gas and the oxygen-containing-gas in a neighborhood of a tangential direction of an inner circumferential wall of the combustion chamber; wherein the tubular flame burner is a multi-stage tubular burner that is unified in a body, by using a plurality of the tubular flame burners, and by connecting the front-end of the tubular flame burner with a smaller inner diameter of the combustion chamber into the rear-end of the tubular flame burner with a greater inner diameter of the combustion chamber.
