Outline of Final Research Achievements

This study attempts to deal with research and development on a low cost solid sensible heat storage system for a central solar power tower plant. Mortal hollow circular cylinder blocks for heat storage using ferronickel slag as a fine aggregate are fabricated. Geopolymer concrete hollow circular cylinder blocks using blast furnace slag as a fine aggregate are also fabricated. The effect of mix of ferronickel slag on the amount of heat storage in the mortar hollow circular cylinder block using the slag as a fine aggregate is evaluated by both heat storage test of the block and numerical calculation of the amount of heat storage based on the unsteady heat conduction analysis. Methods of analysis and optimum design for the solid sensible heat storage using hollow circular cylinder block fabricated reusing slags are established.
