Comparative Analysis of the Efficiency of Alternative Electric and Thermal Technologies of Natural Gas Energy Production

Resumo

This article presents a comparative analysis of the efficiency of six conventional energy technologies for the production of electrical and thermal energy and three original alternative technologies developed at the Joint Institute for High Temperatures, Russian Academy of Sciences, that have been proposed for implementation. The thermal efficiency of all the of the considered options for the ratio of electric and thermal energy production typical of Russia’s average climatic conditions is compared with a unified methodology. The efficiency values of electric power generation based on heat consumption is compared for all the options. It is demonstrated that, when domestic gas turbine units are used, the efficiency of the electric energy generation of the developed technologies can significantly exceed that in the best existing energy technologies with the use of promising, imported, high-power gas turbines. These advantages can be attained not only by increasing the parameters of the working fluid but also by optimizing the structure of the thermodynamic cycle of the energy technology.
