PROBLEM TO BE SOLVED: To provide a radiant tube burner which uses two heat storage parts and is miniaturized by forming piping systems for exhaust gas and combustion air into one system, and in which it can be easily changed over whether the exhaust gas or the combustion air is caused to pass through the two heat storage parts.SOLUTION: A radiant tube burner 1 is provided that includes: a heat storage body holding part 8 having a cylindrical inner space; a rotary heat storage part including heat storage bodies 12, 13 at both sides of a partition wall 11; and a rotary actuator 25 for turning the rotary heat storage part. In the radiant tube burner 1, when the rotary heat storage part is inserted into the heat storage body holding part 8, the inner space is partitioned into two divided spaces, combustion air piping 5 for supplying combustion air and an intake 4 for supplying combustion air to a burner are communicated with one divided space, and an exhaust port 6 and exhaust gas piping 7 for discharging exhaust gas are communicated with the other divided space.SELECTED DRAWING: Figure 1 |
