PROBLEM TO BE SOLVED: To provide a chemical heat storage device in which a reactive medium can be recovered even when the temperature of exhaust gas is low.SOLUTION: A chemical heat storage device 12 includes an annular first reactor 13 arranged around an oxidation catalyst 4, first storage equipment 15 which is connected to the first reactor 13 and adsorbs and stores a first reactive medium (NH), an annular second reactor 16 arranged outside the first reactor 13, and second storage equipment 18 which is connected to the second reactor 16 and adsorbs and stores a second reactive medium (CO). The first reactor 13 includes a first reaction material such as MgClwhich chemically reacts with the NHto generate heat for heating the oxidation catalyst. The second reactor 16 consists of a plurality of reaction chambers 16a divided along the circumferential direction of the oxidation catalyst 4. Each reaction chamber 16a includes a second reaction material such as MgO which chemically reacts with the COto generate heat for heating the first reactor 13. |
