Japanese Patent JPS648277
Kind Code:
B2
Abstract:
PURPOSE:To lower as far as possible both the amount of a heating gas that will mingle with a gas to be heated and the amount of the gas to be heated that must be supplied, by introducing the gas to be heated that has remained in a heat exchanger into another heat exchanger from which the remained heating gas has been evacuated after the completion of the heat accumulation thereby recovering said gas to be heated, and purifying said gas to be heated followed by introducing into a circulating circuit. CONSTITUTION:A gas 1e to be heated flows into a heat exchager is wherein it is heated, and at the same time a heating gas 1i flows into a heat exchanger 2a wherein the heat is accumulated. On the other hand, in the heat exchanger 3a, the remaining heating gas has been evacuated, the gas 1f to be heated that has remained in a heat exchanger 4a flows into the heat exchanger 3a and then into a tank 2b that has been evacuated. Thus, the heating gas remained in the heat exchanger 3a wherein heat accumulation has been completed is accompanied by a gas to be heated that has remained in the heat exchanger 4a and flows into a tank 2b. Therefore, the heating gas can be prevented from mixing into the circulating circuit for the gas to be heated. Further, the gas 1g to be heated is fed from a tank 1b that is filled with the gas to be heated that has remained in the heat exchanger 2a into an apparatus 1b for purifying a gas to be heated wherein the impurities are removed and the gas flows into a tank 3b.
