The usage of waste heat of industrial processes is a huge potentiality to increase energy efficiency and to reduce primary energy input. Up to now, the waste heat of industrial furnaces is frequently utilized only partially. A new, innovative and modular heat store upgrades the possibilities of waste heat recovery. The heat store is characterized by:
Together with the plant operator, a concept for the integration of the heat store and for the use of the stored heat is developed.
Based on this, the heat store is equipped with an automatic GIWEP control for heat charging and discharging. The control system comprises:
