RADIANT TUBE BURNER, AND ATTACHING STRUCTURE FOR RADIANT TUBE

摘要

PROBLEM TO BE SOLVED: To suppress deterioration of junction strength of a radiant tube by optimizing an attaching structure to a holding part 6 of the radiant tube 1 and suppressing an occurrence of a gap by a difference of coefficients of thermal expansion in a radiant tube burner provided with the ceramics made radiant tube 1 exposed in a furnace and formed with a combustion chamber in an interior, and the holding part 6 fixed to a furnace wall and holding the radiant tube 1. SOLUTION: A cylindrical sleeve 2 enveloping a rear end side outer surface of the radiant tube 1 via an adhesive layer 4 is fixed to the holding part, and a slit 2d extending along a cylinder axis direction is formed in a predetermined arrangement area L in the cylinder axis direction of the sleeve 2.
