Title:
CHEMICAL HEAT STORAGE APPARATUS
Document Type and Number:
WIPO Patent Application WO/2017/081955
Kind Code:
A1
Abstract:
This chemical heat storage apparatus (10) is equipped with a recovery control unit (23), a storage unit (24), and a failure detection unit (25). The recovery control unit (23) controls a recovery pump (16) into operation when the temperature of a reactor (11) is higher than T1 but lower than T2, the recovery pump (16) recovering an NH3 from the reactor and forcing the NH3 into an adsorber (12). When the temperature of the reactor is T2 or more, the recovery control unit (23) controls a valve (15) to an open position so that the NH3 can be recovered from the reactor and forced into the adsorber. The storage unit (24) stores the estimate value of the NH3 recovery rate of the adsorber when the recovery pump (16) is in operation and the valve is in an open position. The failure detection unit (25) calculates the actual measurement value of the NH3 recovery rate of the adsorber when the recovery pump (16) is in operation and the valve is in an open position. On the basis of the amount of deviation between the actual measurement value of the NH3 recovery rate of the adsorber and the estimate value of the NH3 recovery rate of the adsorber as stored in the storage unit, the failure detection unit (25) determines the failure in a reactive medium supply system (26) between the reactor and the adsorber.
