Abstract
Apparatus, systems and methods are provided for the improved use of waste heat recovery systems which utilize the organic Rankine cycle (ORC) to generate mechanical and/or electric power from waste heat of large industrial machines (prime movers) generating power from biofuel such as biogas produced during the anaerobic digestion process. Waste heat energy obtained from prime mover(s) is provided to one or more ORC system(s) which are operatively coupled to separate electrical generator(s). The ORC system includes a heat coupling subsystem which provides the requisite condensation of ORC working fluid by transferring heat from ORC working fluid to another process or system, such as anaerobic digester tank(s), to provide heat energy that enhances the production of fuel for the prime mover(s) without requiring the consumption of additional energy for that purpose.
