“…This method is applicable to one of the most promising, in our opinion, schemes of the cogeneration plants, which is the regenerative air turbine cogeneration (RATC) system. The advantages of this scheme are described in [21]. The analysis of such a scheme was not performed by any of the above methods, unlike the known CGAM CHP system [22].…”

“…In [21], we performed a detailed thermodynamic analysis of the ideal and actual regenerative cycles with the determination of the optimal energy parameters of the RATC system. However, it is not enough to optimize the technological scheme based on energy characteristics only, as suggested in [23].…”

“…• Environmental advantages -the ability to operate the system with gas obtained as a result of thermal treatment of municipal solid waste. The boiler operates at almost atmospheric pressure with less emission of harmful substances into the atmosphere [21]. First, consider the thermodynamic model of the RATC system, which is a component of the general thermoeconomic model of the RATC system, and is necessary to determine the parameters of the working substance in the main elements of the scheme:…”

“…Consequently, the heat produced in the heat exchanger will be considered as a secondary product. In addition, as shown by Rusanov et al [21], for systems operating on the Brighton air cycle, optimal modes should be determined taking into account the operation of this cycle, and not only by system electrical efficiency. This is due to the fact that when the electrical efficiency increases with increasing π c , the cycle work decreases due to the increased consumption of electrical energy by the compressor.…”

The concept of optimization of operating and design parameters of the regenerative air turbine cogeneration (RATC) system is proposed. To determine the energy efficiency indicators of this system, its thermodynamic analysis was performed. At the same time, it is shown that it is not correct to search for the optimal parameters of such a system only by energy indicators, and modern thermoeconomic methods should be more actively involved in pre-design practice, which allow a comprehensive evaluation of the efficiency and economy of the energy-technological system as a whole and its individual elements. Therefore, on the basis of the data obtained during the thermodynamic analysis, exergy destruction and losses in the main system elements were calculated. Then, using the structural-variant method in combination with the graphical apparatus of C-curves, the pre-project thermoeconomic optimization of the RATC system was performed. This made it possible to choose the optimal operating and design parameters of the system and determine the minimum cost for its creation and operation throughout the entire life cycle, taking into account the thermodynamic perfection of the main system elements. Each variable operating mode parameter of the system serves as a kind of navigator when searching for the option of system parameters that is optimal in terms of energy and economic indicators, which is accompanied by graphic visualization. Therefore, the proposed approach makes the optimization of the system being designed convenient and clear. It can be used in the optimal design of various types of thermal transformers and other energy-technological systems.
