A radiant tube burner device and a heat storing element unit have a simple structure, high reliability, and excellent heat storing performance. A radiant tube burner device used for a heating device for a continuous steel-strip annealing facility has a burner device (11) mounted on the one end side of a radiant tube (5), an air supply pipe (15) for supplying combustion air to the burner device (11), a gas discharge pipe (17) connected to the other end side of the radiant tube (5), a pair of heat storing elements (19, 21) provided in a piping system for interconnecting the gas discharge pipe (17) and the air supply pipe (15), a first four-way switching valve (31) provided in a piping system for interconnecting the gas discharge pipe (17) and the pair of heat storing elements (19, 21), and a second four-way switching valve (33) provided in a piping system for interconnecting the air supply pipe (15) and the pair of heat storing elements (19, 21). |
