In this work, a study of the efficiency of carbon dioxide energy cycles of different architecture is carried out. The relevance of these technical solutions in modern conditions is shown. Basic options of zero emission thermodynamic cycles using CO2 as an cycle fluid are presented. It is shown that the efficiency of the analyzed CO2-cycles with an initial temperature of 1000 °C will be 54-58%, depending on their configuration. It is presented that the efficiency can be increased up to 65% with an initial temperature increase up to 1500 °C.

It is created technology of evaluation of CPP application efficiency in consideration of energy budget and systems' limitations. It is determined efficient TPP capacity structure of SFD.

The technique of the analysis of combined-cycle power plants with binarity coefficient which is less than one is offered. The technique enters a heating indicator. The index characterizes warmth anneafling by combined-cycle power plant. Plant is equipped with the steam turbine with heating selection of steam. Plants with afterburning and dual-fuel plants are considered. Interference of again entered index, degrees of binarity, various efficiencies is at each other shown in this article. The heat balance diagrams and the power streams’s integrated charts of combined-cycle plants on the basis of the gas-turbine unit V64.3 are submitted. The calculated quantitative values of an efficiency on power generation on thermal consumption, coefficient of binarity, a heating index, the relative annealing of warmth and other characteristics for some of the actual or being in a stage of the project combined-cycle plants are given.
