Experimental and Analytical Examination in Mortar Hollow Circular Cylinder Block for Heat Storage

Abstract

A low cost solid sensible heat storage system using concrete and industrial waste as a heat storage medium has been considered in the heat storage system of concentrating solar thermal power generation plant. Ferronickel slag produced as a by-product in the refining of ferronickel can be used as a low cost solid sensible heat storage medium. In this study, the effect of ferronickel slag mix on heat storage in the mortar hollow circular cylinder block using ferronickel slag as a fine aggregate is evaluated by both heating test of the heat storage block and numerical calculation of heat storage based on unsteady heat conduction analysis.
