<p>A heat storage device (10) is provided with: a reactor (11) positioned in the upstream side of a diesel oxidation catalyst (DOC) (4) in an exhaust pathway (3); a medium tank (13) for storing ammonia which is connected to the reactor (11) via a conduit (12); and a cooling fan (14) for sending the cooling air for cooling the reactor (11) back inside the reactor (11). In the reactor (11), a compact (chemical heat storage material) comprising CaCl2, an air flowpath for circulating cooling air and an ammonia flowpath for circulating ammonia (NH3) which chemically reacts with CaCl2 are arranged.</p> |
