Analysis of the working conditions of the recuperative and heat recovery systems of a compressor-less combined cycle gas turbine

This article is dedicated to consideration of a variant of the implementation, developed by the authors, of the oxygen-fuel cycles- compressor-less combined-cycle plants in comparison with combined-cycle power. The analysis of heat exchangers’ the working conditions of a compressor-less combined cycle gas turbine (CCGT) carried out. The proposed solution ensures efficient recovery and utilization of the heat of the exhaust working fluid, which ensures the fuel efficiency of the installation as a whole. The heat utilization process in these devices allows to fully take advantage of the direct-contact heat exchangers. The proposed fundamental solution of the heat and mass transfer process organization of the compressor-less combined cycle gas turbine (CCGT) allows increasing the fuel utilization factor and reducing the amount of harmful emissions into the atmosphere.
