4. Example of the industrial application of thermocline storage to recover industrial waste heat: Eco-Stock® solution

4.1 Implementation context

The Eco-Stock solution ^® , developed by Eco-Tech Ceram, is a solution for capturing, storing and recovering high-temperature waste heat using thermocline systems. This solution has been implemented on an industrial scale to recover waste heat from clay tile and brick factories .

The terracotta manufacturing process comprises several stages: mixing and kneading clays, pressing, drying for several hours at low temperatures (below 100°C) and firing at high temperatures (up to 1,000°C). Dryers and kilns generally run on burners...
