Research Abstract |
A novel chemical heat storage system is proposed to utilize waste heat from industrial chemical processes. In this system, steam can be effectively generated by adsorption heat using the direct heat exchange method. The cycle experiment which consisted of steam generation and regeneration of adsorbent was carried out under atmospheric pressure. As a result, steam could be generated for each cycle. The feasibility of this process was experimentally confirmed. Steam with high pressure up to 4 atm was generated from water at 80 degC. Numerical models for steam generation and regeneration were developed to study the effect of operating conditions on the process. Calculated results agreed with the experimental ones.
