The Analysis on Powering the ORC (Organic Rankine Cycle) System by Heat Storage Device

orc2019 Tracking Number 98

Some of the heat sources, such as e.g. waste or solar, are featuring floating thermal and output characteristics. Heat recovery from such sources is difficult while the changes in the heat source output and heat carrier temperature negatively influences the continuity and operational conditions of energy conversion systems and devices. Especially vapour power plants, such as ORCs, should utilize the heat sources having steady thermal and output characteristics. The heat source floating characteristics can be stabilized using the heat storage devices providing the thermal energy accumulation at stable output and temperature level. Heat storage device can be adopted as a steady-level heat source for ORC system. In this paper the results of the experiments carried on the ORC system powering from heat storage system, which were carried out on a prototype ORC test-stand are presented. The results showed that adopting the heat storage devices for powering the ORC systems is a promising way of utilizing the floating waste and solar heat sources.
