PROBLEM TO BE SOLVED: To provide a chemical heat storage system capable of improving heat utilization rate more than heretofore.SOLUTION: A chemical heat storage system 1 comprises: a reactor 11 filled with a chemical heat storage substance capable of reversibly performing hydration reaction and dehydration reaction; an evaporation condenser 12 configured such that steam to be used for hydration reaction of the chemical heat storage substance can be generated and steam generated by dehydration reaction of the hydrated chemical heat storage substance can be condensed; a communication path 13 for communicating the reactor 11 and the evaporation condenser 12 and circulating steam; and a flow rate adjusting means 14 which is disposed on the communication path 13 and adjusts flow rate of steam circulated within the communication path 13. The chemical heat storage system 1 is configured such that reaction heat accompanied by hydration reaction of the chemical heat storage substance in the reactor 11 and evaporation latent heat accompanied by generation of steam in the evaporation condenser 12 can be recovered and is configured such that a part or all of recovered reaction heat can be heat-exchanged with a portion 2 of a system outer part. |
