AB  - This paper presents experimental tests of lignite from the Kostolac open-pit mine, used to operate the boiler of the Kostolac B2 thermal power plant in 2022. Experimental tests were conducted to determine the emission characteristics and carbon emission factor and compare these values with those taken and determined in 2016. A total of 31 samples taken in April 2022 were tested. As with our previous work, the experimental methodology includes proximate analysis, ultimate analysis and determination of calorific value, for the 'as received', 'as determined' and dry basis. Corresponding correlations were established for the tested Kostolac lignite. The emission characteristics of the Kostolac lignite from 2022 were compared with the corresponding values from 2016. Certain changes in the values of the carbon emission factor over time are a regular phenomenon and therefore periodic sampling and experimental determinations are inevitable to follow the changes in the values. For this change in coal properties, new values for the carbon emission factor are proposed, which should be used to calculate the total carbon dioxide emissions in the last period.

AB  - Energy costs are rapidly rising around the world and it is important to find a way to reduce energy consumption. Energy consumption in buildings can account for up to 40% of total energy consumption in developed European countries due to an increase in living space per person, an increase in the need for air conditioning, an increase in the number of appliances used in households, and other factors. Due to the increasingly frequent high temperatures during the summer and the increase in electricity consumption, it is very important to find a way to decrease indoor temperatures in urban residential buildings without using more energy, given the severe energy crisis that has engulfed Europe and the high percentage of energy and electricity consumption in the residential sector. Installation of phase changeable materials is one method for improving the thermal envelope of a building by increasing the thermal capacity of the envelope and thus affecting the reduction of indoor temperature oscillations and, consequently, reduction of summer electricity consumption. In this study, the TRNSYS software package was used to simulate and compare the indoor air temperature in typical detached houses built in period 1946 and 1970 in the Belgrade area, for both, the case without and the case with installed phase change (PCM). It was shown that incorporating a PCM with a melting temperature of 25?C into the inter-floor construction of the house could significantly improve comfort conditions by reduce indoor temperature fluctuations during the warm period without consuming additional energy. When the temperature outside is around 30?C, the maximum air temperature in the house drops by about 2?C.

AB  - This paper presents the importance of the carbon emission factor, the need for its regular determination with the aim of calculating CO2 emissions as accurately as possible, and the monitoring of changes in the value of the emission factor and emissions. This is shown by the example of lignite from the open-pit mine “Kostolac”, which was sampled and experimentally investigated in order to determine the emission characteristics and compare them with the emission characteristics of lignite from the same open-pit mine from the previous year. At the Institute of Nuclear Sciences "Vinca", Laboratory for Thermal Engineering and Energy, an experimental and computational methodology was developed, including proximate analysis, ultimate analysis and the determination of the lower heating value. Based on laboratory tests, the necessary correlation dependencies were determined and a comparison of the values and the dependency curves of the emission factor on the lower heating value was carried out. When comparing the results, it was found that the emission factor changes for a certain value. If one takes into account other variables that are included in the calculation of the annual emission values, such as the consumption of lignite in the thermal power plant, certain small changes in the values of the emission factor are no longer so negligible and have a considerable influence on the difference in the amounts of CO2 emitted. For this reason, regular sampling and experimental determinations are essential to track the changes in emission factor values.

AB  - By ratifying the Paris Agreement, the Republic of Serbia has committed to reduce greenhouse gas emissions by 13.2% by 2030 compared to the 2010 levels. About 70% of electricity is generated in thermal power plants that use low-quality domestic lignite as fuel. Greenhouse gas emissions from electricity generation amounted to 51.5 Mt CO2eq in 2014. The Republic of Serbia has a significant renewable energy source (RES) potential for electricity generation. This research aims to define sustainable scenarios for the years 2030 and 2050 in the transition process of the electricity generation sector in the Republic of Serbia. These scenarios provide an opportunity to gradually reduce CO2 emissions by 2050, with the goal of zero-emission electricity generation in 2050. The scenarios were created using the hourly electricity balance of the Serbian power system in the EnergyPLAN software, with 2010 as the base year for the calculations. The proposed scenarios promote the sustainable use of RES for electricity generation in the Republic of Serbia. The results show a reduction in CO2 emissions of 35% and 59% in 2030 for the scenarios and 66% and 100% in 2050 compared to the reference year 2010.

AB  - Hydrogen produced by the thermal decomposition of natural gas in a low-temperature plasma
reactor is the subject of this study. The main advantage of plasma pyrolysis of natural gas is that a high
yield of hydrogen can be obtained without the emission of carbon monoxide or carbon dioxide since the
main products of the process are carbon in the solid state and hydrogen. The use of plasma allows the
decomposition of natural gas without the use of catalysts, which is one of the main problems of current
technologies for hydrogen production from this feedstock. In this paper, an analysis of the process is
presented using a thermodynamic equilibrium model based on the minimum of the Gibbs function in
the temperature range of 500-2500 K. Undesirable components in the system such as carbon dioxide,
hydrogen cyanide and nitrogen compounds such as ammonia and nitric oxide are evaluated. The
analysis showed the useful energy of the system per kilogram of feedstock and the efficiency of the
high-temperature plasma decomposition process in terms of hydrogen produced. The results of the
numerical analysis showed an optimal temperature for the process evaluation of about 1200 K, at which
an efficiency of about 50 % is achieved.

AB  - This paper proposes a mathematical modelling approach to determine the thermodynamic equilibrium of chemical systems in order to optimise the operating parameters of the plasma chemical processes in a lowtemperature thermal plasma pilot reactor with a direct current electric arc for the treatment of hazardous waste containing polychlorinated biphenyls. The model is primarily based on the principles of mass action and minimum Gibbs free energy. The obtained results can serve as a basis for multi-criteria optimisation based on ecological aspects, reduction of energy consumption and the possibility of using the produced synthetic gas for energy recovery in the process. The analysis carried out clearly showed the advantages of using water vapour as a plasma working medium and the appropriate mixing of the organic waste containing polychlorinated biphenyls with used engine oil for enriched syngas production. The presented analysis determines the optimal reactor temperature for an ecologically efficient treatment and shows possibilities for energy recovery in the process. The proposed model can also be used for other chemical reactors and for the treatment of other chemical substances

AB  - Incorporating phase change materials (PCM) into building structures as passive latent heat thermal energy storage technologies offers a potential solution for reducing energy demand and regulating thermal comfort in occupied buildings. Integrating PCM into lightweight walls can improve their thermal performance by increasing building heat capacity and decreasing energy consumption. The effects of phase change materials (PCMs) added to the thermal envelope of lightweight residential containers on building thermal comfort are investigated in this study. The simulations were run for the summer period because it is difficult to achieve thermal comfort without using a lot of energy at that time. Thermal comfort is highly dependent on both, climatic conditions and the materials used to construct the building's thermal envelope, and the simulation was performed for weather conditions in five different geographic locations using TRNSYS simulation software. The paper examines the effects of PCM on indoor air temperature, specifically on reduction of maximum air temperature and temperature fluctuations

AB  - Due to the excessive use of air conditioners and heating systems, energy consumption by the builiding sector has been growing significantly in recent years, which leads to the accelerated depletion of conventional energy sources and to the fact that renewable energy sources are becoming more and more popular. Phase change materials are suitable for use in latent heat energy storage technology due to their high storage density and stable thermal properties. The thickness of phase change materials (PCMs) added to the thermal envelope of a lightweight building is investigated in this study. The simulations were run for 7 days in July, which was determined to be the hottest period of the summer based on the Meteonorm weather file, and when it is difficult to maintain thermal comfort without using a lot of energy. The thermal behavior of the building without PCM and with builtin PCM in the envelope of the building in one wall on the south side and on the ceiling, with different thicknesses of phase-changing material was simulated and the results obtained were analyzed with the aim of establishing which thickness of phase-changing material is optimal for installation in the envelope of the building

AB  - Devolatilisation is a process of volatile components formation that takes place immediately after the drying process and precedes combustion or gasification. The paper presents the procedure for determining the composition of devolatilisation products on the wheat residue biomass sample. The components considered devolatilisation products are carbon monoxide, carbon dioxide, hydrogen, water vapor, hydrogen sulfide, ammonia, ethene, methane, and tar. The procedure relies on two independent models that adopt two distinct principles. The first model of energy and mass balance does not consider the analysis of the influence of temperature, and therefore the system is indeterminate. The second model that involves the temperature influence is based on defining the equilibrium composition of gaseous components of the devolatilisation process by applying the principle of minimum Gibbs function. This model gives the gas-phase composition of the water/carbon dioxide, carbon monoxide/carbon dioxide, and hydrocarbons/carbon dioxide systems. Combining these two models using an iterative procedure leads to an exact composition of the devolatilisation products, including tar as a condensed product. The analysis was performed in the temperature range of 700–950 K. The model is validated against already published numerical and experimental work and presented a high level of agreement. The main advantage of the proposed combined parametric modelling relies on the simplicity of its input data which refers to the proximate and the ultimate analysis of the biomass feedstock.

AB  - Population growth, consumerism, and industrial development have led to the increased hazardous and solid municipal waste amounts worldwide. Incineration, gasification, pyrolysis, smelting, or glazing have been proposed to treat the hazardous waste before disposal in inert soil. This paper discusses the management of hazardous waste, proper legislation treating this field, the quantity of the hazardous waste substances, and energy production potentials from this type of waste materials in the territory of the Republic of Serbia. This paper gives an overview of the available thermal treatment methods and waste-to-energy technologies in terms of their performance and environmental impact suitable for the Republic of Serbia. The analysis showed that proper development of this industrial sector could contribute to increased opportunities for new jobs to help mitigation of environmental issues, which will significately improve overall Serbian economy.

AB  - The paper presents the methodology for the determination of the average annual efficiency of CHP plants. The method is based on determining the effective efficiency on three different loads in order to obtain a functional dependence of the efficiency and unit load. For the calculation of the average annual efficiency, the annual load of the plant and the calculated functional dependence of the efficiency are taken into account. When calculating the effective efficiency, both methods, direct and indirect, were used. The methodology for determining the average annual efficiency of the CHP plant was implemented on the example of the cogeneration gas power plant "VELEBIT 3B" within the petroleum company NIS, Serbia. The presented methodology can be applied to similar plants for the determination of average annual efficiency.

AB  - Oxy-fuel combustion is the most promising carbon capture and storage technology, which eliminates carbon dioxide emissions into the atmosphere and also decreases nitrogen oxides emissions thereby lowering global warming potential. In order to implement oxy-fuel combustion technology in full scale power plants, its costs, mainly connected with the amount of pure oxygen produced, must be lowered. The main hypothesis is that it is possible to maintain similar velocity and heat transfer distribution while maintaining stable and efficient burner operation during both combustion technologies modifying burner aerodynamics. Excess oxygen is chosen as a representative parameter of burner's performance and investigation is carried out for four different oxy-fuel burner oxygen excess ratios (λ: 0.8, 0.98, 1.07, and 1.24) together with reference air combustion case. This study suggests a workflow, based on semi-industrial experimental investigations and computational fluid dynamics model composed of advanced sub-models for different combustion phases for development of real scale dual-mode coal swirl burners able for efficient operation during both combustion regimes. The results show that the temperature in near-burner zone and nitrogen oxides emissions increase, while carbon monoxide emissions decrease with the increase of burner oxygen excess ratio, and stable combustion with similar velocity and temperature distributions for both combustion modes is achieved for oxygen excess ratio of 1.07, with decrease in nitrogen oxides and carbon monoxide emissions during oxy-fuel combustion. The performed study demonstrates that it is possible to choose the appropriate burner settings regarding nitrogen oxides and carbon monoxide emissions and burner's ability to operate stably in both air and oxy-fuel combustion modes. © 2019 Elsevier Ltd

Analysis of quality of the selected options (energy systems) in respect to sustainable development by compare of their general index of sustainability is presented. Methodology of multi-criteria analyse of thermal power plant unit can show decision makers how to find best available options when the social indicators impact is leading. The aim of this paper is to choose the criteria for the evaluation of the available options, determine the relative importance of specific criteria and present methodology of multi-criteria analysis in the decision-making process.",

AB  - The paper presents a possible approach for creating business decisions based on multi-criteria analysis. Seven options for a possible revitalization of the thermal power plant Kolubara-A Unit No. 2 with energy indicators of sustainable development (EISD) are presented in this paper. The chosen EISD numerically express the essential features of the analyzed options, while the sustainability criteria indicate the option quality within the limits of these indicators. In this paper, the criteria for assessing the sustainability options are defined based on several aspects: economic, social, environmental and technological. In the process of assessing the sustainability of the considered options the Analysis and Synthesis of Parameters under Information Deficiency (ASPID) method was used. In this paper, the EISD show that production and energy consumption are closely linked to economic, environmental and other indicators, such as economic and technological development of local communities with employment being one of the most important social parameter. Multi-criteria analysis for the case study of the TPP Kolubara-A clearly indicated recommendations to decision makers on the choice of the best available options in dependence on the energy policy.

AB  - New system for start-up and flame support based on coal gasification by low temperature air thermal plasma is planned to supplement current heavy oil system in Serbian thermal power plants in order to decrease air pollutions emission and operational costs. Locally introduced plasma thermal energy heats up and ignites entrained coal particles, thus starting chain process which releases heat energy from gasified coal particles inside burner channel. Important stages during particle combustion, such as particle devolatilisation and char combustion, are described with satisfying accuracy in existing commercial computer fluid dynamics codes that are extensively used as powerful tool for pulverized coal combustion and gasification modeling. However, during plasma coal gasification, high plasma temperature induces strong thermal stresses inside interacting coal particles. These stresses lead to thermal shock and extensive particle fragmentation during which coal particles with initial size of 50-100 mu m disintegrate into fragments of at most 5-10 mu m. This intensifies volatile release by a factor 3-4 and substantially accelerates the oxidation of combustible matter. Particle fragmentation, due to its small size and thus limited influence on combustion process is commonly neglected in modelling. The main focus of this work is to suggest novel approach to pulverized coal gasification under high temperature conditions and to implement it into commercial comprehensive code ANSYS FLUENT 14.0. Proposed model was validated against experimental data obtained in newly built pilot scale direct current plasma burner test facility. Newly developed model showed very good agreement with experimental results with relative error less than 10%, while the standard built-in gasification model had error up to 25%.

Shodno preuzetim obavezama, od 2005. godine započelo se sa rekonstrukcijama i modernizacijama elektrofilterskih postrojenja svih termoblokova u sastavu JP EPS. Na termoelektrani 'Nikola Tesla B' je tokom 2011. godine izvršena rekonstrukcija i modernizacija elektrofilterskog postrojenja bloka B2, dok je rekonstrukcija elektrofilterskog postrojenja bloka B1 obavljena tokom 2012. godine. Cilj obavljenih rekonstrukcija, finansiranih donacijama Evropske Unije, bio je da se emisija praškastih materija u dimnom gasu iz ovih blokova spusti na nivo ispod 50 mg/Nm3, za normalne uslove i pri garantovanim radnim uslovima kotla i elektrofilterskog postrojenja. U radu su prikazani rezultati merenja koncentracija praškastih materija u dimnom gasu iza elektrofiltera, obavljenih u skladu sa zahtevima međunarodnih standarda ISO 9096 i EN 13284-1 nakon rekonstrukcije elektrofilterskih postrojenja termoelektrane TENT B, kao i rezultati ispitivanja obavljenih nakon isteka perioda od godinu dana od završetka rekonstrukcija. Dobijeni rezultati potvrđuju da je izlazna koncentracija praškastih materija ispod garantovane vrednosti, čime je potvrđena uspešnosti izvedenih rekonstruktivnih zahvata.
AB  - The requirements of the international document Directive 2001/80/EC relating to limitation of the particulate matter emissions from large thermal power plants have been incorporated into relevant regulations of domestic legislation. In accordance with the commitments, since 2005 it was started with reconstruction and modernization of electrostatic precipitator system of all thermal units within the Electric Power Industry of Serbia. The reconstruction and modernization of electrostatic precipitator system of the unit B2 of thermal power plant 'Nikola Tesla B' was done during 2011, while the reconstruction of the electrostatic precipitator system of the unit B1 was conducted in 2012 year. One of the main objectives of performed reconstructions and modernizations, financed by donations of the European Union, was to decrease the emission of particulate matter in the flue gas from these units down to level below 50 mg/Nm3, in normal conditions and under guaranteed operating conditions of the boiler and electrostatic precipitator system. This paper presents results of the measurements of particulate matter concentration performed in accordance with standards ISO 9096 and EN 13284-1, immediately after the reconstruction and shortly before the end of the period of about 1 year after the reconstruction, as a part of control and guarantee investigations of the reconstructed electrostatic precipitators of Thermal Power Plant Nikola Tesla B units. In addition, this paper presents re sults of labosatory analysis of the coal samples taken during test, working parameters of the unit and upgraded electrostatic precipitator system during the tests as well as results of the calculations. The results of the measurements confirm that particulate matter concentration in the flue gas from reconstructed electrostatic precipitators fall down below guaranteed values, thus confirming the effectiveness of the reconstructive operations.

Two units were put in operation before more than fifty years and in order to extend the lifetime of these blocks in the process of revitalization, in this paper, beside an existing option which considers coal (lignite) combustion, are analysed possible options of thermal power units with gas and renewable energy sources: biomass, renewable solid fuels, waste materials, wind and sun. Paper presents seven energy system options of the thermal unit status which are described with suitable chosen indicators in respect to different aspects of sustainability: economical, ecological, social and resources indicators. In this paper energy indicators are defined as a tool for the sustainability assessment of energy system options. ASPID method of multi-criteria assessment was used to calculate general index of sustainability and obtained ranking of options. This study presented and analysed cases, with predefined constraints when priority has environmental indicator and different conditions where one of sub-indicators have priority, as an example of applying multi-criteria method.

AB  - Despite benefiting from vast fuel reserves, combustion of low-rank coals is commonly characterized by low thermal efficiency and high pollutant emissions, partly due to high moisture content of the coals in question. Thus, removal of moisture from low-rank coals is deemed an important quality upgrading method. The paper provides an overview of the current status of low-rank coal upgrading technologies, particularly with respect to utilization of drying and dewatering procedures. In order to examine the influence of relevant parameters on the moisture removal process, a model of convective coal drying in a packed, as well as in a fluid bed combustion arrangement, is developed and presented. Product-specific data (intraparticle mass transfer, gas-solid moisture equilibrium) related to the coal variety addressed herein (lignite) are obtained through preliminary investigations. Effective thermal conductivity of the packed bed as defined by Zehner/Bauer/Schlunder is used to define heat transfer mechanisms occurring in the packed bed.

AB  - The paper addresses results for the case of convective drying of particulate solids in a packed and in a fluid bed, analyzing agreement between the numerical results and the results of corresponding experimental investigation, as well as the differences between packed and fluid bed operation. In the fluid bed simulation model of unsteady simultaneous one-dimensional heat and mass transfer between solids, gas phase and bubble phase during drying process, based on two-phase bubbling model, it is assumed that the gas-solid interface is at thermodynamic equilibrium. The basic idea is to calculate heat and mass transfer between gas and particles (i.e., the drying process) in suspension phase as for a packed bed of particles, where the drying rate (evaporated moisture flux) of the specific product is calculated by applying the concept of a drying coefficient. Mixing of the particles (i.e., the impact onto the heat and mass transfer coefficients) in the case of fluid bed is taken into account by means of the diffusion term in the differential equations, using an effective particle diffusion coefficient. Model validation was done on the basis of the experimental data obtained with narrow fraction of poppy seeds characterized by mean equivalent particle diameter (d(s.d) = 0.75 mm), re-wetted with required (calculated) amount of water up to the initial moisture content (X-0 = 0.54) for all experiments. Comparison of the drying kinetics, both experimental and numerical, has shown that higher gas (drying agent) temperatures, as well as velocities (flow-rates), induce faster drying. This effect is more pronounced for deeper beds, because of the larger amount of wet material to be dried using the same drying agent capacity. Bed temperature differences along the bed height are significant inside the packed bed, while in the fluid bed, for the same drying conditions, are almost negligible due to mixing of particles. Residence time is shorter in the case of a fluid bed drying compared to a packed bed drying. (C) 2012 Elsevier Ltd. All rights reserved.
