PURPOSE:To simplify the structure of an apparatus, as well as to meet the temperature in discharged steam to the purpose for use, by forming a high temperature zone and a low temperature zone in a melted salt in a tank in the vertical direction, and by connecting a high- temperature steam pipe to the upper parts, and a low-temperature steam pipe to the lower parts of heat transfer pipes which are provided multi-stagedly in a heat accumulating tank in the direction of height. CONSTITUTION:When a melted salt 15e is heated by high-temperature steam fed from a steam drum 1 or a superheater 2, the heated part is gradually spread and is expanded from the upper part of a layer down. On the other hand, when a low-temperature steam from a low- temperature steam pipe 7 is fed into a tank 15 under the condition that a valve 3 is closed, the steam is heated while it is fed out of a tank 15, becoming a high-temperature steam. In the former case, part of steam passing through a heater 2 is fed into a steam feed pipe 22 through a high-temperature steam pipe and is mixed with the low-temperature steam from the low-temperature steam pipe 7, to make a purposed temperature condition. In the latter case, the high-temperature steam from a pipe header 15c in the upper part of a tank 15 is fed through a pipeline 6, and at the same time, the low-temperature steam from an accumulator 4 is fed through a pipeline 7, and is mixed to make a purposed temperature. A steam in constant temperature can continuously be supplied by exhaust heat from a converter. |
