Abstract: A power plant with heat transfer, in which power is generated by an arbitrary number of heat engines, described above and illustrated in FIGS. 1 to 18. is disclosed. The heat engines (A) are arranged in series with a cooling medium (22) and a heating medium (30) passing through them in a counter flow principal. After exiting the last heat engine the heated-up cooling medium is used as a combustion air. The heating medium (30) exiting in the opposite direction the last heat engine (A) can be used further on for heating purposes or other heating consumers.
