Abstract
This article provides the dataset of working fluid parameters and performance characteristics for the oxy-fuel, supercritical CO(2) cycle by the thermodynamic optimization procedure employed in the research article "Thermodynamic optimization and equipment development for a high efficient fossil fuel power plant with zero emissions" (Rogalev et al., 2019) [1]. The performance characteristics of the different air separation units, which were used for the investigation of an influence of the produced oxygen purity on power consumption, are presented. Moreover, the methodology for the evaluation of gross and net efficiency is described. The working fluid parameters and performance characteristics are subdivided into several tables differing from each other by the values of initial pressure.
