Thermodynamic Analysis of Advanced Gas Turbine Combined Cycle Integration with a High-Temperature Nuclear Reactor and Cogeneration Unit

Abstract

The EU has implemented targets to achieve a 20% share of energy from renewable sources by 2020, and 32% by 2030. Additionally, in the EU countries by 2050, more than 80% of electrical energy should be generated using non-greenhouse gases emission technology. At the same time, energy cost remains a crucial economic issue. From a practical point of view, the most effective technology for energy conversion is based on a gas turbine combined cycle. This technology uses natural gas, crude oil or coal gasification product but in any case, generates a significant amount of toxic gases to the atmosphere. In this study, the environmentally friendly power generation system composed of a high-temperature nuclear reactor HTR integrated with gas turbine combined cycle technology and cogeneration unit is thermodynamically analysed. The proposed solution is one of the most efficient ways for energy conversion, and what is also important it can be easily integrated with HTR. The results of analysis show that it is possible to obtain for analysed cycles thermal efficiency higher than 50% which is not only much more than could be proposed by typical lignite or hard coal power plant but is also more than can be offered by nuclear technology.

Characteristics Analysis of Combined Cycle Coupled With High Temperature Gas-Cooled Reactor Based on Progressive Optimization

“…Gomez et al (2009) and Gomez et al (2010) conducted optimization studies on the CC-HTGRs, which mainly focused on the optimization method, and research on the system characteristics that were lacking. Jaszczur et al (2018) and Jaszczur et al (2020) carried out thermodynamic analyses and compared the characteristics of CC-HTGRs coupled with single-pressure, double-pressure, three-pressure, interstage superheating, and reheating HRSGs. The authors and their research team of this study conducted studies on CC-HTGRs, including comparisons of the different cycle schemes (Wang et al, 2015;Wang et al, 2016), cycle characteristic analyses (Chen, 2001), cycle optimization (Yang et al, 2020), and offdesign performance analysis (Qu et al, 2019).…”

Power Optimization of a Modified Closed Binary Brayton Cycle with Two Isothermal Heating Processes and Coupled to Variable-Temperature Reservoirs

“…Due to the characteristics of high power density (PD), small vibration, high automation, low operating pressure and easy lubrication, gas turbine plants (Brayton heat engine cycle) are extensively applied in the fields of aviation, energy, transportation, etc. According to the different working fluid (WF) circulation modes, the Brayton cycle is divided into open and closed cycles, and many works concerning the classical thermodynamic analyses and optimizations for various Brayton cycles have been performed [1][2][3]. The WF of closed Brayton cycle is not directly connected with the atmosphere, and does not participate in the combustion process.…”

A neural network model for UAV propulsion system

“…In the context of environmental problems, the effect of greenhouse gases is one of the issues that need urgent solutions by scientists. The solutions focus more on increasing the efficiency of energy conversion systems, determining the performance parameters according to off-design points, and modeling the environmental impacts of the energy conversion system in all operating conditions (partial-load, full-load) while in the design phase (De Sa and Al Zubaidy, 2011;De Santoli et al, 2020;Jaszczur et al, 2020;Kvamsdal et al, 2007;Gialanella and Malandruccolo, 2020;Lefebvre, 1985;Popli et al, 2013;Prakash and Davies, 2020;Rahman et al, 2011;Rice et al, 2020).…”
