摘要

Most excess heat/cold in industrial processes is unrecovered due to intermittency and variability in grades (dueto e.g. temperatures) and amounts (due to e.g. flow rates), which complicates the heat-to-power conversionand heat upgrade using traditional technologies. The decoupling of heat sources/sinks and thermal powerutilisation via generation/heat upgrade enabled by the integration of a suitable storage system has the potentialto address the challenges. The aim of this study is to develop a framework based on heat storage (latent andthermochemical), heat-to-power (organic/steam Rankine cycle, Kalina cycle, etc.) and/or heat upgrade (heatpumps, etc.) options, already available or nearly ready for the market, for the utilization of the industrial wasteheat. A wide temperature range is considered which spans applications to as wide as the food and steel sectors.Based on an extensive literature survey, mutual links are established on the basis of temperature and illustratedin maps. This facilitates the primary screening of the latent heat and thermochemical storage systems for heatto power and heat upgrade applications. With such generalized maps, the application of the Rankine cycle(both direct and reverse) using refrigerants in relationship to the thermal energy storage technologies isdiscussed.
