PROBLEM TO BE SOLVED: To contrive a further reduction in cost due to a simple structure by having a constitution placing an ignition device through a refractory material in addition to a fuel feed member, and by integrating the ignition device and the fuel feed member. SOLUTION: This fuel feed mechanism has a constitution, in which a refractory material 6 that is provided with a channel 4 comprising a part of a combustion part is placed in the front side of a packed bed 2 of a heat reservoir 3, and in which a fuel feed member 7 is placed from the upside to the channel 4 through this refractory material to feed fuel into the channel. In this case, the mechanism has such constitution as to place an ignition device 8 through the refractory material in addition to the fuel feed member 7. As a result, the structure in the rear side of a burner becomes simple, and a further reduction in cost and space saving in the rear side of the burner can be permitted. |
