| Research Abstract |
Feasibility of hybrid thermal energy system which combines magnesium oxide/water chemical heat storage system and high-temperature process was discussed experimentally as an energy saving system. New heat storage composite material mixed with expanded graphite and magnesium hydroxide was demonstrated as high-performance material compared with conventional pure magnesium hydroxide. Pelletized material using the composite was developed also. The pellet was charged into a packed bed reactor of chemical heat storage system and measured its thermal performance. The chemical heat storage system using the composite was expected to contribute on load leveling and energy saving of a high-temperature process.
