PURPOSE:To prevent the deflection of respective glass tubes and the deviation of the centers of the tubes from one another from occurring and at the same time keep the gaps of respective gas flow passages constant by a structure wherein a plurality of spacers are interposed between the outer peripheral surface of one glass tube and the inner peripheral surface of another glass tube in such manners as distributed circumferentially in a burner consisting of a plurality of concentric glass tubes. CONSTITUTION:Respective spacers are interposed between the inner peripheral surfaces of respective tubes 6, 7 and 8 and the outer peripheral surfaces of respective tubes 5, 6 and 7 in such manners as distributed circumferentially in a burner consisting of a plurality of the concentric glass tubes 5, 6, 7 and 8. In addition, the spacers 5a-5d and the spacers 5e-5h are respectively welded at the tip part side and at the base end part side of the glass tube 5, the spacers 6a-6d and the spacers 6e-6h are respectively welded at the tip part side and at the base end part side of the glass tube 6, and further the spacers 7a-7d and the spacers 7e-7h are respectively welded at the tip part side and at the base end part side of the glass tube 7. At the same time, the tips of the spacers 5a-5h closely contact with or are held with minute gaps with the inner peripheral surface of the glass tube 6. Similar relationship exists between the tips of the spacers 6a-6h and the inner peripheral surface of the glass tube 7 and between the tips of the spacers 7a-7h and the inner peripheral surface of the glass tube 8.
