Аннотация: Four options for the power cycle using carbon dioxide as a working fluid during oxygen combustion of gaseous fuel are considered. In all the cases, heat is supplied within the zone of supercritical parameters of CO2. The fundamental difference in options lies in the method of increasing the working fluid pressure. The heat is supplПоказать полностьюied to the cycle in the combustion chamber, and the cycle operation is accompanied by continuous updating of the working fluid, since part of CO2 and all steam obtained during fuel combustion are removed from the cycle. It is shown that cycles with a single-stage pressure increase by a pump have the highest thermal efficiency, reaching 64.5 %. The effect of thermodynamic parameters on the energy characteristics of cycles has been estimated quantitatively.
