Title:
CHEMICAL HEAT STORAGE DEVICE
Document Type and Number:
Japanese Patent JP2016196969
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To appropriately prevent an abnormal overpressure state within a reactor and a storage unit.SOLUTION: A chemical heat storage device 10 includes: a heater 11 having a reaction material 13; a storage 12 for storing NH; a supply pipe 15 that communicates the heater 11 with the storage 12 to make NHflow between the heater 11 and the storage 12; a valve 16 arranged in the supply pipe 15 to open/close a flow passage of NHbetween the heater 11 and the storage 12; reactor pressure control means 19 for making NHin the heater 11 flow in one direction from the heater 11 to the storage 12 when the pressure in the heater 11 reaches preset first set pressure or larger with the valve 16 closed; and storage unit pressure control means 22 for discharging NHin the storage 12 to outside of a reaction system when the pressure in the storage 12 reaches preset second set pressure or larger with the valve 16 closed. The second set pressure is larger than the first set pressure.SELECTED DRAWING: Figure 1
