HEAT TRANSFER ANALYSIS OF THE INORGANIC DECOMPOSITION CHEMICAL REACTION THERMAL STORAGE SYSTEM.

The heat transfer characteristics of the chemical thermal storage system based on decomposition reactions of the inorganic hydroxides Mg(OH)//2 and Ca(OH)//2 are carried out numerically and experimentally to investigate the configuration effects on storage performance. Experimental results show that the change in the temperature distribution and interface location of a fin-equipped packed bed can be validly simulated by a numerical model. In addition, the suitable configuration for high performance storage is found to be 0. 4-0. 6 cal/cm**2 - sec of power input, 0. 03-0. 04 cm of fin thickness, 0. 05-0. 1 cm of bottom plate thickness, 20-30 cm**3/cm of packed capacity, and the ratio of fin height to interval up to 10-12.
