    Bojan Dimitrijević, Bogoljub Vučković, Radmila Gaćina (2023)
    Geology explorations in KCM runs from 1936. year up to these days and still ongoing. Results in >7,200 drill holes with ≈600,000 m of core drilling and gave lignite ore resources of > 4,1Bt, which 1,15Bt are excavated since 1986. of XIX up to early years of XXI century. For further mining operations in open pits stay 1,5Bt of lignite. Under waste heaps are ≈80 km2, additional 85 km2 should be filled. All of that masses/areas were, are ...

  • Available technological procedures for capturing CO2 in the industrial and power generation sectors

    Lola Tomić, Vesna Karović Maričić, Dušan Danilović, Branko Leković, Miroslav Crnogorac (2021)
    Climate change is a major environmental issue caused by anthropogenic emissions of greenhouse gases. Capturing CO2 and storing it in suitable geological formations is one of the main technological solutions that can provide mitigation of CO2 emission into the atmosphere. Capturing CO2 represents the first phase in process of carbon capture and storage, and includes the application of various technologies for the separation of CO2 produced in the energy and industrial sectors. There are four main systems for capturing ...

  • Determining the Impact of Cutting Elements State on the Bucket–Wheel Excavator Vibration and Energy Consumption

    Filip Miletić, Predrag Jovančić, Miloš Milovančević, Miloš Tanasijević, Stevan Đenadić (2022)
    Background There are two types of specifc sizes’ measurements. The frst is the measurement of energy consumption in a working technological process, and the second is the measurement of vibration, which is displayed over amplitudes of speed. There is an interplay between these two processes. Increasing the power consumption, the value of the vibration speed amplitudes increases. Purpose The process of the determination of machining parameters was based on minimizing the power consumption and vibration of the cutting tool, ...

  • Препреке декарбонизацији система даљинског грејања у Србији - ставови представника топлана

    Марија Живковић, Дејан Ивезић, Бобан Павловић, Дејан Стојановић (2024)
    Производња топлоте у системима даљинског грејања у Републици Србији тренутно се заснива искључиво на процесима сагоревања, с доминантним уделом природног гаса из увоза. Иако су технологије за коришћење обновљивих и алтернативних извора енергије добро познате, њихова примена у системима даљинског грејања у Републици Србији још увек је занемарљива (око 2%). Како би се убрзао и олакшао процес транзиције ка обновљивим изворима енергије и разумело тренутно стање и перспектива, спроведена је анкета међу представницима топлана Србији. Циљ је био ...

  • Valorization of non-balanced coal reserves in Serbia for underground coal gasification

    David Petrović, Lazar Kričak, Milanka Negovanović, Stefan Milanović, Jovan Marković, Nikola Simić, Ljubisav Stamenić (2019)
    In the name of a better and safer energy future, it is our responsibility to focus our knowledge and activities to save on imported liquid and gas fossil fuels, as well as coal on which energy security of Serbia is based. The rationalization in the use of available energy resources certainly positively affects economy and the environment of a country. This paper indicates motivations for the application of the underground coal gasification process, as well as surface gasification for ...

  • Hidrogeotermalni resursi teritorije grada Beograda

    Ana Vranješ (2012-12-12)
    Republika Srbija je izrazito bogata hidrogeotermalnim resursima. Podzemne vode satemperaturama preko 20oC (pa do 96oC, Vranjska Banja) relativno su dobro iskorišćene.Nasuprot njima, podzemne vode sa temperaturama do 20oC do sada uglavnom nisu bilepredmet istraživanja sa bilo kog aspekta izuzev za potrebe vodosnabdevanja. Razvojemsistema toplotnih pumpi, mogućnosti višenamenskog korišćenja ovih voda značajno suuvećane.Teritorija Beograda odlikuje se značajnim resursima podzemnih voda, pre svega u okvirualuvijalnih peskovito-šljunkovitih naslaga i neogenih tortonsko-sarmatskih krečnjačkihnaslaga.

  • Industrial Waste Heat Potential for Meeting Heat Demand in the Republic of Serbia

    Dejan Ivezić, Marija Živković (2023)
    Finalna potrošnja energije u industrijskom sektoru čini skoro 25% finalne potrošnje energije u Republici Srbiji. Procenjuje se da je 50-70% potrošnje energije u industriji namenjeno proizvodnji toplotne energije u različitim industrijskim procesima. Deo proizvedene toplotne energije se nepovratno gubi kao energija odvedena u okolinu: prenosom toplote kroz zidove procesne opreme, dimnim gasovim, otpadnim vodama itd. Korišćenjem otpadne toplote povećava se efikasnost korišćenja primarne energije i smanjuje ukupna potreba za energijom. Otpadna toplota se može koristiti u samom industrijskom objektu ...
