化学蓄熱システム
Document Type and Number:
Japanese Patent JP6973322
Kind Code:
B2
Abstract:
To provide a chemical heat storage system whose heat storage tank (reaction tank) is simple and can be miniaturized, which prevents a chemical heat storage medium from being deteriorated.SOLUTION: A chemical heat storage system 1 used for a co-generation system includes; an engine 3 that generates heat; an exhaust gas boiler 5 that generates steam by the heat of the exhaust gas of the engine 3; a reaction tank 9 which stores a chemical heat storage medium 7 for absorbing heat by a dehydration reaction and generating heat by a reaction with steam; a first heat exchanger 11 for exchanging heat with the chemical heat storage medium 7 in the reaction tank 9; and a condensation evaporator 13 provided so as to communicate with the reaction tank 9 for performing condensation and evaporation of water. At heat storage time, the steam generated by the exhaust gas boiler 5 is supplied to the first heat exchanger 11, the chemical heat storage medium 7 is heated, and the heat is stored. At heat radiation time, water to be heated is supplied to the first heat exchanger 11, steam is supplied from the condensation evaporator 13 to the chemical heat storage medium 7, and the water supplied to the first heat exchanger 11 is heated by the heat generation of the chemical heat storage medium 7 to generate steam.SELECTED DRAWING: Figure 1
