PURPOSE:To efficiently purify an intermediate heat medium regardless of the operation of a power plant by providing a purifying system having a heater of the intermediate heat medium and an adsorbing section purifying it regardless of the operational condition of the plant. CONSTITUTION:An intermediate heat medium of a full exchange quantity is prepared in advance in the storage tank 15A of a separate purifying system, and after the full exchange quantity of the intermediate heat medium deteriorated within a limit is recovered in sequence in a tank 10, the purified and clean intermediate heat medium in the storage tank 15A is transferred into the evaporator 1. Thereby, the clean intermediate heat medium is obtained in the evaporator 1, and a normal plant operation is available. On the other hand, the deteriorated intermediate heat medium recovered in the tank 15B can be purified by an adsorbing and removing unit 19 and a foreign matter removing unit 17 regardless of the operational condition of the evaporator 1. |
