Systems and methods provide for capturing heat energy in a power generation system. The system includes: a first compressor configured to exhaust a first compressed, heated air flow; a heat exchanger connected to the first compressor and configured to rece...

Disclosed is a method and a system. The method and system involve compressing an atmospheric gas stream to form a supercritical atmospheric gas stream, forming at least a first stream from the supercritical atmospheric gas stream, directing the first strea...

Disclosed are a method and system involving pressurizing an atmospheric gas stream to form at least a compressed atmospheric gas stream, directing the compressed atmospheric gas stream to a first regenerator for cooling, pressurizing to above a second pred...

A method for controlling emissions of a heat engine includes sucking air (Q A ,Q A ') from outside, burning a mixture including fuel (Q F ) and at least a fraction (Q A ,') of sucked air (Q A ,), whereby exhaust gas (Q E ) is produced, and detecting concen...

The exhaust gas from a gas turbine (3) is fed to a first heat exchanger (5) to heat the air supply (41) from a compressor (9) supplying an air turbine (7). Further heat is extracted from the exhaust gas in a second heat exchanger (11) together with the exh...

Gas turbine system is constructed such that no fuel gas compressor is used and a turbine is operated at low temperature so that a life of the system is elongated and the safety is enhanced. Air compressed at a compressor (11) of about 200 DEG C enters a he...
