Development of Sensible Heat Storage Materials Using Sand, Clay and Coal Bottom Ash

In this paper, the mechanical and thermal properties of a sand-clay ceramic with additives coal bottom ash (CBA) waste from incinerator power plant are investigated to develop an alternative material for energy storage (TES). Ceramic balls developed at 1000°C 1060°C using sintering or firing method. The obtained ceramics were compressed compression machine thermally analyse Decagon devise KD2 Pro analyser. A muffle furnace was also used cycling 610°C. It found that CBA increased porosity, which resulted in increase axial tensile strength reaching 3.5 MPa ceramic. required TES selected. Their volumetric heat capacity, conductivity range respectively 2.4075 MJ·m-3·°C-1 3.426 their 0.331 Wm-1·K-1, 1.014 Wm-1·K-1 depending on sand origin, size temperature. selected formulas have good stability because most fragile specimens after 60 cycles did not present any cracks. These allow envisioning use as filler thermocline (structured beds) Concentrating Solar Power plants. And other applications like solar cooker dryer.
