“…Consequently, it drives the interest of scholars and practitioners around the globe and stimulates research on the Russian energy and fuel complex. For instance, there are well established and continuously developing groups of scientific knowledge devoted to Russia's traditional energy resources: (a) Oil (Kryukov and Moe, 2018;Vatansever, 2017;Kapustin and Grushevenko, 2018;Tuzova and Qayum, 2016;Depellegrin and Pereira, 2016;Locatelli and Rossiaud, 2011;Locatelli, 2006;Reynolds and Kolodziej, 2007); (b) natural gas (Pierk and Tysiachniouk, 2016;Orazalin and Mahmood, 2018;Shvarts et al, 2016;Talipova et al, 2019;Visenescu, 2018;Mitrova et al, 2016;Korppoo, 2018); and (c) coal (Gorbacheva and Sovacool, 2015;Grammelis et al, 2006;Das, 2001;Alekseenko et al, 2018;Krasil'nikova, 2001;Artobolevskiy, 2003;Sperkach, 2010;Tumanovskii, 2017;Lakhno, 2015).…”

The authors argue that the contemporary scholarship on hydro energy in Russia lacks a comprehensive overview of development trends, global and regional challenges, and future prospects in connection with the ongoing processes in other sectors of the national economy. Consequently, this paper addresses the gap existing in the scholarship by providing a holistic view of the current state of Russia's hydro energy. It also identifies and discusses the key developmental constraints, including the general economic and political situation developing both in Russia and in the world, negative trends in the country's wholesale electricity market and the long-term capacity market, the Russian Government's focus on development of nuclear power stations and not hydroelectric power stations, as well problems of ensuring the technical and environmental safety of hydropower facilities. Finally, the paper outlines prospects of hydro energy in Russia, taking into account global, regional, and national trends in energy development

“…At present ironmaking is connected with significant overconsumption of coke. Only 80 % of total coke quantity is suitable for black furnace because of it's fraction [1]. At the same time coking coal deposits in the world are equal to approximately 400 billion tones [2,3] and rate of their extraction has increased by 200% over the last 10 years [4].…”

A mathematical model based on the use of artificial neural networks for forecast of resistance coefficient of burden to the gas at the bottom of the blast furnace with using of coke nut by processing of data array for the OJSC "MMK" blast furnaces (capacity of 1370 m3), equipped with a chute-type bell-less charging device has been created. This test has shown the adequacy of the model to real data. Influence of such factors as characteristics of blast (oxygen content, temperature, natural gas and water steam consumption), iron ore (raw material consumption per time unit, FeO, MgO, Al2O3 content, fraction, basicity), coke (wearability (M10), impact strength (M25), coke strength reactivity (CSR), coke reactivity index (CRI)) on gas dynamics variation at the lower part of the black furnace have been determined. Average relative prediction error does not exceed 0.28 %, the maximum of the sample is 2.82 %. The oxygen content in the blast has the biggest effect on the burden resistance coefficient. When oxygen concentration is more than 25.2 %, the increase of natural gas consumption improves gas-dynamic conditions in the lower part of blast furnace. With the decrease of oxygen content in the blast, the influence of natural gas consumption on coefficient of burden resistance varies in the opposite direction. The reduction of coke wearability (M10) by 0.05 % abs. or the increase of coke strength reactivity (CSR) by 0.14 % abs. has compensated negative effect of coke nut (consumption 4 kg/t of iron) on blast furnace operation.
