FIXING STRUCTURE OF RADIANT TUBE AND RADIANT TUBE BURNER

摘要

PROBLEM TO BE SOLVED: To realize a fixing structure of a radiant tube 1 in a radiant tube burner 100 comprising a ceramic radiant tube 1 internally forming a combustion chamber 9, and a member 3 for holding the radiant tube wherein shift of the radiant tube 1 can be suppressed and sealing performance of the holding member 3 and the radiant tube 1 can be prevented from lowering by employing an appropriate structure for fixing the radiant tube 1 to the holding member 3. SOLUTION: The holding member 3 is provided with a sleeve face 2a surrounding the outer surface of the radiant tube 1 on the rear end side, and a face 5a abutting on the end face of the radiant tube 1 on the rear end side wherein an adhesive layer 4 is provided on the sleeve face 2a side in a gap formed between the holding member 3 and the radiant tube 1 and a seal layer 15 is provided on the abutting face side 5a of the adhesive layer 4 in the gap or on the forward end side of the sleeve face 2a.
