Claims

[Claims for Utility Model Registration] 1. A plurality of heat transfer accelerators are fitted in series in the exhaust side tube body, and the furnace inner end is fitted in the exhaust side tube body on the downstream side of the exhaust side of the heat transfer accelerators. A first tube consisting of a cylindrical air permeable solid closed by a sealing plate.
The partition is arranged at a position inside the furnace from the inner wall surface of the furnace, and a second partition made of a cylindrical breathable solid is arranged at a position downstream of the exhaust gas from the first partition. The partitions are connected via a seal ring fitted into the exhaust side tube body to form a heat exchange chamber surrounded by the two partitions, and a heat exchanger for preheating combustion air is provided in the heat exchange chamber, A self-recirculating burner is attached to the burner side tube body, and includes an injector tile, a fuel nozzle, a combustion air nozzle concentric with the nozzle, and a recirculation chamber, and the preheated air that has passed through the heat exchanger is 1. A radiant tube comprising: a pipe for introducing the combustion air into the nozzle; and a pipe for introducing part of the exhaust gas that has passed through the heat exchange chamber into the recirculation chamber. 2. The radiant tube according to claim 1, wherein the injector tile of the self-recirculating burner is provided at a position protruding from the inner wall surface of the furnace to the inside of the furnace. 3. The radiant tube according to claim 1 or 2, wherein the tip of the fuel nozzle of the self-recirculating burner protrudes from the tip of the combustion air nozzle and opens within the injector tile. 4. The radiant tube according to claim 1, 2, or 3, wherein the injector tile of the self-recirculating burner is fixed in an inner cylinder fitted into the burner-side tube body.
