Abstract

The present invention provides a waste heat recovery system, comprising: an internal combustion engine for supplying a high grade waste heat thermal resource fluid and a low grade waste heat thermal resource fluid; an intermediate thermal cycle by which an intermediate fluid is vaporized by means of the high grade waste heat thermal resource fluid and is expanded within a first turbine, whereby produce is produced; and an organic thermal cycle by which an organic motive fluid is preheated by means of the low grade waste heat thermal resource fluid and is vaporized by means of the discharge of the intermediate fluid from the first turbine, said vaporized organic motive fluid being expanded in a second turbine, whereby power is produced.
