More Information
Summary:This invention relates to a radiant tube burner used for heating a heating furance, and aims at minimizing the occurrence of NOx during combustion and forming the radiant tube burner to a structure suitable therefor. This invention aims at simplifying the controlling of a fuel supply system and an air supply system, and preventing the necessity of a coking operation. This invention also aims at providing a combustion control method suitable for a radiant tube burner. To achieve these objects, the free ends of fuel nozzles in the present invention, for example, nozzles (11) serving also as pilot nozzles and air throats (13) are disposed in the end portions of a radiant tube (3), and combustion air ejection ports (33) of the air throats (13) are provided eccentrically so as to contact or get close to an inner circumferential wall surface of the radiant tube (3). A controller (307) for subjecting the burner to alternating combustion is also provided.
