PROBLEM TO BE SOLVED: To provide a heat transfer pipe failure detecting device for finding the failure of a heat transfer pipe earlier without stopping operation, and a heat storage device equipped therewith. SOLUTION: The heat storage device 11 comprises a detection chamber 31 provided outside an outer case 23, a temperature sensor 32 for detecting a temperature in the detection chamber 31, and a control device 51 for determining whether the heat transfer pipe 25 is failed or not in accordance with the temperature in the detection chamber 31 detected by the temperature sensor 32. Heat carrier vapor generated in an inner case 21 is guided via a vapor lead-out pipe 41 to the detection chamber 31. When the temperature in the detection chamber 31 reaches a heat transfer pipe failure determining temperature, the control device 51 determines that the heat transfer pipe 25 is failed. The failure of the heat transfer pipe 25 is therefor found earlier. The failure of the heat transfer pipe 25 can be detected without stopping the operation of the heat storage device 11 or emptying the heat transfer pipe 25 once. COPYRIGHT: (C)2004,JPO&NCIPI
