A RADIANT TUBE BURNER EQUIPPED WITH A COMBUSTION TUBE HAVING RADIAL OPENINGS TO VITIATE AIR WITH COMBUSTION PRODUCT

摘要

A radiant tube burner equipped with a combustion gas circulating combustion container is provided to preclude the temperature from going up and nitrogen oxide from occurring by dropping the oxygen concentration of the second air and slow-moving the response to the second air and the main combustion gas. A radiant tube burner equipped with a combustion gas circulating combustion container is composed of a fuel supply pipe(5); a radiant tube(2) connected with the fuel supply pipe, wherein the outer air is flowed; and a combustion container(3) formed in the radiant tube and communicated with the fuel supply pipe to have a fuel nozzle(10) and a first air supply nozzle at one side. The radiant tube is comprised by forming plural auxiliary combustion gas exhaust ports(20) at the outer wall surface of the combustion container and reducing the inlet of a main combustion gas exhaust port(21) where the fuel discharged through the fuel nozzle is combusted in the combustion container and discharged.
