Organic rankine cycle for energy recovery system

This book contains the successful invited submissions [1–9] to a Special Issue of Energies entitled “Organic Rankine Cycle for Energy Recovery System”, focusing on a modern technology committed to energy saving and thus capable of producing positive environmental outcomes. Indeed, the organic Rankine cycle (ORC) is a thermodynamic concept already demonstrated as an engineering viable solution for waste heat recovery systems. Industrial realizations of the ORC in large- to small-scale applications are currently available, with power sizes ranging from few tens of kW to several MW of electric power output. In the near future, this technology can play an increasing role within the energy generation sectors and can help achieve the carbon footprint reduction targets of many industrial processes. As also demonstrated within this book, there are still many un-used hot streams available for recovery in various stationary power generators for civil and tertiary applications and in several highly intensive industries. Additional applications can come from the transportation sector, where waste engine heat in heavy vehicles and ships can be used to achieve fuel savings. Moreover, low-enthalpy flows from renewable sources can be exploited in thermodynamic cycles based on the Rankine architecture
