<P>PROBLEM TO BE SOLVED: To provide a chemical heat storage device that outputs heat of high temperature while suppressing pressure rise in the device. <P>SOLUTION: The chemical heat storage device is provided for heating an exhaust emission control device 7 by reaction heat generated in producing calcium hydroxide by reaction of calcium oxide and water, and storing the heat by separating calcium hydroxide into calcium oxide and water by external heat as the heat generated outside of the system. The device includes first and second reactors 11, 12 receiving calcium oxide, a storage container 2 for storing the water, a condenser 6 for condensing water vapor, a first passage 41 for guiding the water stored in the storage container 2 to the first reactor 11 in a liquid state, a second passage 42 for guiding the water vapor generated in the first reactor 11 to the second reactor 12, a third passage 43 for guiding the water vapor generated in separating calcium hydroxide in the second reactor 12 to the condenser 6, and a forth passage 42 for guiding the water in the liquid state condensed by the condenser 6 to the storage container 2, and the second reactor 12 is thermally connected with the exhaust emission control device 7. <P>COPYRIGHT: (C)2012,JPO&INPIT |
