Abstract

A rankine cycle arrangement, the arrangement (100) comprising: an expander (1), a heat exchanger (2) connected to an inlet channel (3) of the expander (1) for heating working fluid to be fed in the expander (1), a condenser (5) connected to an outlet channel (6) of the expander (1) for cooling working fluid expanded in the expander (1), and a pump (8) connected to an outlet (9) of the condenser and to an inlet (10) of the heat exchanger for rising pressure of working fluid. The arrangement further comprises an ejector (11) comprising a high-pressure inlet (12), a low-pressure inlet (13), and an outlet channel (14). The ejector (11) is connected in parallel with the expander (1) such that a first portion of working fluid is capable to bypass the expander through said ejector (11).
