AB  - Emission factors (EFs) of gaseous pollutants, particulate matter, certain harmful trace elements, and polycyclic aromatic hydrocarbons (PAHs) from three thermal power plants (TPPs) and semi-industrial fluidized bed boiler (FBB) were compared. EFs of particulate matter, trace elements (except Cd and Pb), benzo[a]pyrene, and benzo[b]fluoranthene exceed the upper limits specified in the EMEP inventory guidebook for all combustion facilities. The comparison of trace elements and PAHs content in fly ashes (FAs) from lignite and coal waste combustion in TPPs and FBB, respectively, as well as the potential environmental impact of FAs disposal, was performed by employing a set of ecological indicators such as crustal enrichment factor, risk assessment code, risk indices for trace elements, and benzo[a]pyrene equivalent concentration for PAHs. Sequential analysis shows that the trace elements portion is the lowest for water-soluble and exchangeable fractions. The highest enrichment levels in FAs are noticed for As and Hg. Based on toxic trace elements content, FAs from TPPs represent a very high ecological risk, whereas fly ash from FBB poses a moderate ecological risk but has the highest benzo[a]pyrene equivalent concentration, indicating its increased carcinogenic potential. Lead isotope ratios for Serbian coals and FAs can contribute to a lead pollution global database.

AB  - Homogeneity of the flue gas-flow through the chamber of an electrostatic precipitator is one of the basic influencing parameter on dedusting efficiency. This paper presents results of a multiobjective optimization study of the flue gas controlling devices of electrostatic precipitator of 324 MWe lignite fired Unit A4 of TPP "Nikola Tesla" in Serbia. The aim was to achieve better flow homogeneity in the cross-section of the precipitator compared to the original design. Additional constraints were to maintain the minimum as possible overall weight of the proposed design as well as pressure drop through the precipitator. Numerical simulations based on CFD were used to investigate dependence of the velocity distribution in the ducts and precipitator’s chamber with respect to the geometrical parameters of tested concepts of turning blades. A series of 22 detailed full-scale numerical models of the precipitator with different concepts of turning vanes designs were developed. Assessment of the flow field uniformity for each tested design was performed based on the analysis of several homogeneity parameters calculated for selected vertical cross-sections of the precipitator. After the reconstruction according to optimized design, results of measurements confirmed significant improvements of the velocity distribution in the vertical cross-sections of the precipitator, increase of dedusting efficiency and reduction of PM emission.

AB  - Ugalj kao fosilno gorivo sadrži brojne prirodne radioaktivne izotope koji pripadaju uranovom i torijumovom nizu, kao i 40K. Najviše se koristi u industriji, kao i u proizvodnji energije. Problem u vezi sa proizvodnjom energije iz uglja je takozvani „energetski otpad“, kao što su pepeo i šljaka, koji predstavljaju nesagorivi i nesagoreli ostatak pri sagorevanja uglja. Ako se pepeo i šljaka odlažu u životnu sredinu, može doći do povećanja i/ili preraspodele prirodnog sadržaja radionuklida. Da bi se utvrdio potencijalni uticaj „energetskog otpada“ na životnu sredinu, uzorci uglja, pepela i šljake iz termoelektrana „Nikola Tesla“ i „Kolubara“ mereni su poluprovodničkim HPGe spektrometrom u Laboratoriji za nuklearnu i plazmu fiziku Instituta „Vinča“. Kao rezultat ovih merenja, dobijene su koncentracije prirodnih radionuklida i veštačkog radionuklida 137Cs kao, što je prikazano u ranije objavljenim radovima. Prikazani rezultati su u saglasnosti sa istraživanjima sprovedenim širom sveta.   Da bi se obezbedila tačnost i preciznost (pouzdanost) dobijenih rezultata merenja, u okviru Laboratorije uspostavljen je program kontrole kvaliteta (QC) i osiguranja kvaliteta (QA).

Tačkasti izvori 60Co i 137Cs se koriste kao kontrolni izvori za proveru položaja pika, ukupne površine ispod pika, FWHM (puna širina na polovini maksimuma pika), FWTM (puna širina na desetini maksimuma pika) i odnos FWHM/FWTM. Pored navedenih karakteristika, redovno se kontroliše i ukupni odbroj prirodnog fona. Svaka od navedenih karakteristika može ukazati na neku nepravilnost u radu detektorskog sistema.   Cilj ovograda je da se prikažu kontrolne karte ispitivanih karakteristika poluprovodničkog HPGe spektrometra korišćenog za merenje uzoraka uglja, pepela i šljake.

AB  - eir daughter products, as well as 40K. It is widely used in industry as well as in energy pro-duction. The problems associated with the production of energy from coal is the so-called “energy waste”, such as ash and slag, which are incombustible and unburnt residue from combustion of coal. If ash and slag are released into the environment an increase and/or redistribution of natural radio-nuclide content can occur. To determine the potential impact of “energy waste” on the environment, samples of coal, ash, and slag from thermal power plant "Nikola Tesla" and "Kolubara" were meas-ured with a semiconductor HPGe spectrometer. Results of activity concentration of natural radionu-clides and artificial 137Cs in coal, slag and ash are presented in few previously published papers and obtained values are in accordance with similar worldwide investigations. o ensure the accuracy and precision (reliability) ofthe obtained measurement results, quality control (QC) and quality assurance (QA) program were established. Internal control includes check-ing of the characteristics of HPGe spectrometer used for measurement of all analysed samples. Point sources of 60Co and 137Cs are used as control sources for checking following characteristics: peak positions, net peak area, FWHMs (Full Width at Half Maximum), FWTMs (Full Width at Tenth Max-imum) and FWHM/FWTM ratios. In addition to the mentioned characteristics, the counting of back-ground is also regularly controlled. Each of the mentioned characteristics may indicate some irreg-ularity in the operation of the detector system and thus could influence reliability of performed activ-ity concentration measurements.The paper presents the control charts of the examined characteristics of the HPGe spectrometer used for measurements of coal, ash and slag samples. The obtained control charts indicate the long-term stability of the spectrometer and hence confirm accuracy and precision of measurement results.

AB  - Heating value is an important indicator for assessment of the coal quality. Machine learning models are powerful computational tools that allow for the analysis of various heat and mass transfer phenomena in energy systems. In this paper, Random forest model for determining the lower heating values of coal from the thermal power plant “Kolubara A” is developed based on proximate and ultimate fuel analysis. A database of the proximate and ultimate fuel analysis values and lower heating value of coal was created by experimental measurements in the accredited test laboratory of the Department of Thermal Engineering and Energy (“VINČA” Institute of Nuclear Sciences). The developed Random forest models, applied to a relatively small database, showed acceptable predictions for the lower heating value based on both the proximate analysis (RMSE = 0.22 MJ/kg and MAPE = 2.26%) and the ultimate analysis (RMSE = 0.64 MJ/kg and MAPE = 6.12%), with better accuracy achieved by the model whose input data consisted of the values of technical fuel analysis.

AB  - The anthropogenic emission of GHG especially CO has to be limited and reduced due to 2 their impact on global warming and climate change. Combustion of fossil fuels in the energy sector has a dominant share in total GHG emissions. In order to reduce GHG emission, European Union established a scheme for GHG allowance trading within the community, and the implementation of the European Union emission trading scheme, which is a key to GHG reduction in a cost-effective way. An important part of emission trading scheme is prescribed methodology for monitoring, reporting, and verification of the emission of GHG including characterization of the local fuels combusted by the energy sector. This paper presents lignite characteristics from open-pit mine Borovica- Pljevlja, which has highest coal production in Montenegro (>1.2 Mt per year), including evaluation of its carbon emission factor based on the laboratory analysis of 72 coal samples. Testing of the samples included proximate and ultimate analysis, as well as, net calorific value determination. In accordance with the obtained results, linear correlations between net calorific value and combustible matter content, carbon content and combustible matter content, hydrogen content and combustible matter content, carbon content and net calorific value, were established. Finally, the non-linear analytical correlation between carbon emission factor and net calorific value for Pljevlja lignite was proposed, as a base for the precise calculation of CO emission evaluation.

AB  - The electrostatic precipitator system of the lignite fired 350 MWe unit B1 of Thermal Power Plant Kostolac B has been modernized during 2014. The results of complex in site measurements, performed in the frame of performance control test at the beginning of the exploitation period of the upgraded electrostatic pre-cipitator proved that, under normal and guarantee working conditions of the boiler and precipitator, the emission of particulate matter do not exceed limiting value. After the period of precipitator further adjustments, five series of meas-urements in the frame of acceptance test were performed in accordance with rel-evant standards. This paper presents results of the investigation of particulate matter concentration, laboratory analysis of the lignite, fly and bottom ash sam-ples, working parameters of the unit and upgraded electrostatic precipitator as well as results of the calculations. The averaged mean particulate concentration at the exit of upgraded electrostatic precipitator of the unit B1 during Acceptance test was below guaranteed value. It is confirmed that adjustments of electrostatic precipitator electrical parameters have improved electrostatic precipitator effi-ciency, as well that electrostatic precipitatorcould work highly efficiently in en-ergy save mode with lower power consumption. © 2018 Society of Thermal Engineers of Serbia.

AB  - In order to compare three different techniques and estimate radiological impact, activity concentration of Pb-210 in coal, slag and ash samples from thermal power plant Nikola Tesla, Serbia, were measured, and results are presented in this study. Determination of Pb-210 was carried out in three ways: using HPGe gamma spectrometer and via in-growth of Po-210 and Bi-210 by alpha-particle spectrometry and proportional counting, respectively. The results obtained for three different techniques were compared. Statistical analysis and comparison of methods were carried out by combination of Z score and chi (2) statistical tests. Tests results, as well as values of measured activities concentrations obtained by alpha and gamma spectrometry, showed that gamma spectrometry is a valid alternative to time-consuming alpha spectrometry for low level activity measurements of Pb-210. This remark is also valid even for gamma spectrometers with poor efficiency in low energy region.

AB  - In the present study, an aluminum alloy A356 composite with addition of 5 wt% fly ash was synthesized and subjected to the cavitation erosion resistance test in order to find out if this material can be used in conditions where the cavitation erosion resistance is expected. Obtained results were compared with that of as-cast aluminum A356 alloy, confirming that composite possessed better cavitation erosion resistance than original alloy and that fly ash can be used as an effective reinforcement in metal matrix composites production. Scanning electron microscopy and optical microscopy was used for microstructural analysis. Phase identification of fly ash was carried out using X-ray diffraction analysis. Several methods for monitoring the cavitation erosion resistance of A356 alloy and corresponding composite were applied, such as: mass loss (Delta m), volume loss (Delta V), level of surface degradatiom (P/Po) and pit depth.

AB  - U odgovarajuće propise domaćeg zakonodavstva uključeni su zahtevi iz međunarodnog dokumenta, Direktiva 2001/80/EC, koji se odnose na ograničenje emisije praškastih materija iz velikih termoenergetskih postrojenja. 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.

AB  - An overview of the current status of low-rank coal upgrading technologies is presented in the paper, particularly with respect to drying and dewatering procedures. In order to calculate the significant parameters of the moisture removal process, a model of convective coal drying in a fluid bed, based on the two-phase (bubbling) fluidization model proposed by Kunii and Levenspiel, is developed and presented. Product-specific data (intraparticle mass transfer, gas-solid moisture equilibrium) related to the particular coal variety addressed here (Kolubara 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 suspension phase of the fluid bed. A completely new set of experimental data obtained has been successfully used to validate the model additionally.

AB  - Coal as the fossil fuel contains naturally occurring radionuclides and belongs toNORM (Naturally Occurring Radioactive Materials). On the other hand, slag and fly-ash belong to TENORM (Technically Enhanced Naturally Occurring Radioactive Material), and if they are released into the environment an increase and/or redistribution of natural radionuclide content can occur. For the purposes of this study, six sets of samples (18 in total) of “Kolubara” coal, slag and fly-ash were collected during the periodical emission tests in May 2012th at steam boilers K3 and K4 of TPP “Kolubara”, Serbia. Coal, slag and fly-ash samples were prepared for analysis (milled, dried, sieved and weighed) by appropriate standard methods. Prepared samples were placedin 125 mL PVC cylindrical boxes, weighted and sealed with natural wax. Sealed samples were measured with a semiconductor HPGe spectrometer (37 % relative efficiency) after the radioactive equilibrium was reached. The obtained values of specific activity for coal (Ac), slag (As) and fly-ash (Af) do not differ significantly compared to the values available in the literature. Analysis of determined mutual ratiosAs/Ac andAf/Ac are consistent, taking into account uncertainties ofactivity concentrations, with values of approximately 2 and 4, forK3, and1.5 and 4, forK4. Discrepancies were notedonly for40K (bothsteam boilers) ofAs/Ac.Results indicate that further investigation with more samples should be undertaken, and also correlation between radiological and proximate analysis should be determined.

AB  - Coal is the main energy source in Serbia. One of the problems associated with the
production of energy from coal is the so-called “energy waste”, such as fly-ash and slag (bottomash), which are incombustible and unburt residue from combustion of coal. Fly-ash and slag are
TENORM (Technically Enhanced Naturally Occurring Radioactive Material), and if they are
released into the environment an increase and/or redistribution of natural radionuclide content can
occur. To determine the potential impact of “energy waste” on the environment, samples of coal,
fly-ash, and slag from thermal power plant “Nikola Tesla” and “Kolubara” were analyzed.
The measured concentrations of natural radionuclides (uranium and thorium series and 40K) in
samples of coal as well as in slag and fly-ash produced by combustion of coal are presented in this
paper. Sealed samples were measured with a semiconductor HPGe spectrometer (37% relative
efficiency) after the radioactive equilibrium was reached. Spectra were recorded and analyzed using
software package GENIE 2K, with additional analysis performed by ANGES software.
The obtained values of specific activity do not differ significantly compared to the values available
in the literature. All the results were further statistically analyzed in order to determine the possible
correlation.

AB  - Numerical modeling is widely used tool for prediction of combustion processes. Computational Fluid Dynamics - CFD models use three kinetic rates for description of the coal combustion processes: coal devolatilization, volatile combustion and char combustion. Reported rates for coal devolatilization vary considerably among the authors depending on the type of experimental systems used in describing the phenomenon. Accurate representation of devolatilization process is necessary in order to perform successful CFD calculations of pulverized coal combustion and gasification. The subject of this work is numerical modeling of Serbian lignite pulverized coal devolatilization in drop tube type laboratory scale reactor. The aim of this study is to evaluate the influence of different devolatilization kinetic factors on total devolatilization time in numerical modeling of pulverized Serbian lignite devolatilization. Nine different devolatilization kinetic rates mostly used in devolatilization numerical modeling are compared in the presented work. (c) 2014 Elsevier Ltd. All rights reserved.

AB  - The lubricated and dry sliding wear behaviour of ZA-27 alloy composites reinforced with Al2O3 particles of size 250 mu m was evaluated. The content of Al2O3 particles in the alloy was 3, 5 and 10 wt.%. Composites were produced by the compocasting process using mechanical mixing of the matrix, i.e. Al2O3 particles as reinforcement were added into the semi-solid ZA-27 alloy by infiltration and admixing. A block-on-disc wear test device was used to evaluate the wear rate, whereat 30CrNiMo8 steel disc was used as the counterface, under dry and lubricated sliding conditions at different specific loads and sliding speeds. Results indicated that the wear rates of the composites were lower than those of the matrix alloy and further decreased with the increase in Al2O3 particles content in all combinations of applied loads and sliding speeds both in dry and lubricated tests.

AB  - Pulverized coal particles concentration distribution across the burners distribution channels, especially where plasma torches are installed, is one of the key issues for efficient implementation of plasma system for liquid fuel free combustion support at the pulverized coal fired boilers. The possibility of pulverized coal particles concentration increase at the lower burner channels of TPP Nikola Tesla - A1 boiler using regulation shutters is analyzed experimentally and numerically. Subject of present work is two-phase flue gas-particles mixture flow in burners distribution channels with regulation shutters installed at the TPP Nikola Tesla A1 boiler. Aim of this work is to optimize position of implemented system of shutters to achieve desired concentration and velocity distribution in channels with plasma torches, using numerical modelling. Experimental investigation was performed for the verification of proposed mathematical model for the prediction of the analyzed two-phase flow. Based on verified model, numerical parametric analysis was done. Obtained results of gas phase velocity field. coal particles concentration field, velocity and concentration profiles clearly show the dependence between shutters position and the coal particles mass flow rate and concentration distribution at the outlet cross-section of the burners distribution channels. According to the numerical optimization results suitable modification of the shutter system is proposed.

AB  - The results of the detailed investigations of behavior of lignites Kolubara and Kovin, in fluidized bed combustion are presented in the paper. Investigation was carried out due to the interest of the Serbian Electric Power Production Company to use CFBC boilers in the process of refurbishment of old pulverized coal combustion boilers. As a part of a feasibility study for CFBC use in power plants in Serbia, investigation of combustion characteristics of lignites was performed using original methodology introduced many years ago by Laboratory for Thermal Engineering and Energy. Methodology was approved by numerous investigations of more than 20 Yugoslav coals for FBC combustion, with the aim to determine design data for bubbling FBC boilers. The main attention in present investigation was paid to the problem of using methodology developed for bubbling FBC in the conditions present in CFBC boilers. Four samples of Kolubara lignite, with heat capacity from 2.5 to 8.5 MJ/kg, and different ash contents were investigated, and also lignite Kovin in the same range of heat capacity. Investigations were performed in three phases: (1) ultimate and proximate analysis, determination of ash sintering temperature by standard method and in fluidized bed laboratory oven, (2) investigations in laboratory fluidized bed furnace and determination of coal particle fragmentation, burning rate, start-up temperature and self-sulfure-capture and (3) investigation of combustion in pilot-plant in stationary combustion conditions. In conclusion, suitability of results obtained in BFBC conditions is approved, and earlier statement that lignites are suitable for BFBC is confirmed by the statement that lignites are even more suitable for burning in CFBC boilers. Considering differences between combustion and flow conditions in bubbling and circulating FBC boilers, behavior of the lignites in CFBC is discussed in details and optimal regime parameters of the CFBC boilers are determined. The results obtained will be used by Serbian Electric Power Production Company for evaluation of bid for CFBC boiler implementation in refurbishment of old thermal power plants.
