Abstract: Energy-intensive industrial processes, such as those occurring in steel billet reheating furnaces, usually release waste heat characterised by a fluctuating and/or intermittent nature, which limits the efficiency of current waste heat recovery systems. In fact, current waste heat recovery systems are usually designed for one single operating point, which forces them to operate at off-design conditions when subjected to power fluctuation of the waste heat.
