📄 Abstract（原文）
Abstract The efficient use of secondary and natural energy resources to generate additional electricity is an important factor in improving the economic performance of industrial sectors. In the mining industry, considerable volumes of secondary and renewable heat resources with temperatures between 27 and 75ºC are available. Their effective utilization is possible through gas turbine systems operating with carbon dioxide as the working fluid. Although thermodynamic tables for carbon dioxide exist, they are difficult to apply in analytical studies involving variable parameters. Simplified analytical equations have been developed for carbon dioxide thermodynamic properties at several isobars within typical gas turbine pressure ranges. However, to determine and analyze optimal gas turbine operating modes when using low-potential heat resources from mining enterprises, it is necessary to have analytical expressions covering the entire temperature and pressure range relevant to turbine operation. Developing such equations was the main objective of this work. The study also demonstrates their practical application using specific thermal source parameters.
