| Outline of Final Research Achievements |
To generate high temperature steam by solar energy, elemental researches for the development of the conversion system applying the chemical heat storage technology are carried out. The major findings are summarized below: Dominant factors in the energy storage process are studied using the numerical model considering transport phenomena occurred in the process. Appropriate operating conditions are shown by the model. To increase mass of steam generated, application of thermal energy storage in the system for the promotion of the preheating process is proposed. Effect of heat capacity of adsorbent on the cyclic operation of the process is studied. As a result, it is found that there is the appropriate heat capacity of adsorbent to increase mass of steam for each condition. In addition, the novel method to enhance heat transfer in the packed bed is proposed. Damage of the adsorbent particles by the cyclic operations is also studied to improve the durability of the system.
