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),

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.

In a system for generating power including a combustion machine and a compressor for compressing incoming combustion air, in which exhaust gases after their expansion in the combustion machine contain both sensible heat and latent heat of vaporization in the form of water vapor, means for recovering heat from said exhaust air compressing means for transferring both latent heat and sensible heat from said exhaust gases to said incoming combustion air before its entry into said compressor and for storing at least a portion of the transferred heat as latent heat, in the form of vaporized water, in said incoming combustion air, and means, arranged between said compressor and said combustion machine, for removing stored latent heat from said combustion air for use in another system, comprising a condensing cooler means for condensing at least a part of the water vapor.
