A PROCESS AND A SYSTEM FOR ENERGY GENERATION UTILISING LIQUID AND/OR GAS HEAT SOURCES ON BOARD NAVAL UNITS

摘要

A process and a system for energy generation aboard naval vessels utilising liquid and/or gaseous heat sources at temperatures ranging between 50 and 800 Celsius degrees deriving from the motor apparatus and/or from the same onboard auxiliary units comprise the following stages: a) indirect heat exchange between said gaseous heat sources and/or direct or indirect exchange with said liquid sources and one or more subsystems capable of generating energy through Rankine thermodynamic cycles where organic fluids ORC (Organic Rankine Cycles) circulate, b) production of mechanical energy by means of ORC subsystems, c) heat removing from the ORC devices to the external environment, d) onboard use of said mechanical energy and/or conversion of mechanical energy produced by the ORC turboexpanders into electric energy by means of electric generators, e) distribution of the electrical energy produced to the onboard electric loads and/or to electric propulsion motors.
