ABSTRACT:
System for waste heat recovery, comprising a combustion machine (2,3) with a compressor (4) for the combustion air (30) and means (7) like a heat exchanger (13) and/or a recirculation duct (14), to transfer heat, contained in the combustion gases (37,38,39) after their expansion in the machine (3), to the combustion air flow (33) before its entry into the compressor (4). Water (8,8') is introduced into the (to be) heated combustion air flow (30,33) cooling it by its evaporation, and the vapor is partially condensed again in a cooler (6) fitted in the compressed flow (34) after leaving the compressor (4). The condensation can take place at higher temperature, thus the system acts as heat pump for the waste heat. The compressed air flow (35) enters extra cooled into the combustion chamber (2) which provides an additional advantage. For the compressor (4), combustion chamber (2) and turbine (3) a normal gas turbine may be used.
