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  - Biomass waste recovery is an environmentally friendly method of waste management and sustainable energy production that effectively reduces greenhouse gas emissions and mitigates climate change. As a result, biomass is emerging as a significant source of renewable energy, replacing fossil fuels to power a green and sustainable society and accelerate the development of a circular bio-economy. Thermochemical conversion processes are the most efficient form of biomass utilization for energy production. Gasification of biomass as one of these processes is given special attention in this paper. The concise fundamentals of this process are presented, the types of gasifiers are described and a brief overview of plasma gasification is given with the highlighted advantages and challenges in its application.

AB  - When we discuss biomass and its use for energy, we always have in mind its benefits, such as its ability to - reduce greenhouse gas emissions by replacing fossil fuels; - increase energy security by diversifying the energy mix and reducing dependence on imported fuels; and - create economic opportunities by promoting rural development, creating jobs, and adding value to waste streams. As a renewable energy source, biomass also has some obstacles to overcome. This paper addresses some of the key technical challenges associated with biomass combustion products - how to increase the ash melting temperature, i.e., reduce the formation of ash deposits on the heating surfaces, and how to reduce the emission of nitrogen oxides. It will also be seen whether it is safe to return all the ash produced by burning this fuel to the ground.

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.

parameters, such as temperature and equivalence ratio on the gasification performance of sewage
sludge from wastewater treatment plants. The parametric study was performed using a onedimensional mathematical model to determine the equilibrium composition of the system. The model
is based on the principle of the minimum of the Gibbs function and uses only the ultimate and
proximate analysis data as input to the model. The output of the model gives the equilibrium
composition of the gasses produced. The parametric analysis was performed in order to determine the
optimal operating parameters of the plasma reactor in order to obtain syngas with the highest heat
value while achieving the maximum efficiency of the process. The collected results can be useful in
further analysis of the gasification processes in plasma reactor, such as exergy analysis and kinetics

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  - The controlled modulation of the nozzle exit velocity acts as a disturbance source, superimposing the natural disturbances in axisymmetric turbulent air jets. The modulation controls the vortex roll-up, and thus the overall vortex structure in the jet. The vortex structures have a significant influence on the heat transfer properties of the jet configurations. The jet can be modulated by an external source of low amplitude oscillations or by self-sustaining oscillations generated by the operation of the specially designed whistler nozzles. The aim of the experimental investigations, mathematical modelling and numerical simulations was to investigate the properties and vortex structures of acoustically modified and non-modified jets and to find an efficient way to control them.This study can serve as a basis for further development and optimisation of technological processes related to air nozzles. The paper presents the results of experimental research and mathematical modelling and numerical simulation of free and impinging turbulent axisymmetric modified and not modified air jets.

AB  - The aim of the article is to show the effects of the main gasifier operating parameters, such as temperature, equivalence ratio, steam-to-fuel ratio, and gasification medium selection, on the gasification performance of sewage sludge. Using the developed one-dimensional mathematical thermodynamic equilibrium model for plasma and fluidized bed gasification, a comprehensive parametric study is established. The model is based on the principle of the minimum of the Gibbs function and uses only the ultimate and proximate analysis data as input to the model. The output of the model gives the equilibrium composition of the gasses produced. When comparing different gasification media, gasification with water steam gives a higher yield of H2 and CO in the syngas produced. Further comparison of the two gasification processes in terms of energy consumption is shown. The collected results can be useful in further analysis of the gasification processes, such as energy and exergy analysis and kinetics.

AB  - Hydrogen produced via the thermal decomposition of natural gas, also known as ‘turquoise’ hydrogen, is the subject of this study. It is expected that ‘turquoise’ hydrogen will play a significant role in the coming energy transition, reducing emissions from fossil fuels in the short term until renewable energy sources are capable of producing enough energy or hydrogen transport becomes feasible on a large scale. The main advantage of the thermal decomposition of natural gas is the possibility of obtaining a high yield of hydrogen without the emission of carbon monoxide or carbon dioxide since the main products of the process are carbon in a solid state and hydrogen. The use of plasma in the process elevates the temperature of the process and increases methane decomposition without the use of catalysts. This paper presents an analysis of the process using a thermodynamic equilibrium model based on the minimum of the Gibbs function in the temperature range of 500-2000 K. As a result of the study, the equilibrium composition of the system in the observed temperature range is presented. Also, attention is given to undesirable components in the system such as carbon dioxide, hydrocyanic acid, and nitrogen compounds like ammonia and nitrogen monoxide. From the point of energy analysis, the useful energy of the system per kilogram of fuel and the efficiency of the process is presented. The results of the numerical analysis show that the efficiency of the process increases with increasing temperature and reaches its maximum at a temperature of 1200 K when an energy efficiency of about 50% is achieved.

AB  - The paper presents the results of lignite Carbon Emission Factor (CEF) determination originating from the Balkan Peninsula, namely Greek and lignites from Turkey, Bosnia and Herzegovina, Serbia, and Montenegro. For the experimental investigation, samples were considered based on as received, as determined, and on a dry basis. The experimental analysis included ultimate, proximate analysis, and heat value determination, according to applicable standards. Based on the results of experimental investigation, the following correlations have been established for all considered lignites: total carbon content on combustible matter content, total hydrogen content on combustible matter content, total carbon content on heat value, and correlation of CEF on lignite heat value. Finally, comparisons of different lignite characteristics were performed, and appropriate conclusions on their emission characteristics are given. Presented results can serve as a base for the determination of unique emission factors for each lignite to be used for precise emission mitigation measures planning in the Balkan region.

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  - Methodology using the thermodynamic equilibrium composition calculation to optimise the high-temperature organic waste treatment in thermal plasma was developed. The methodology was demonstrated in the case of high-temperature treatment of polychlorinated biphenyl (PCB) in a thermal plasma reactor using two different working media, air and water vapour. Calculated results obtained in this analysis show composition of combustible and harmful chemical species formed in the PCB oil decomposition process. Optimisation of the composition of the combustibles can suggest the most economical parameters of the process. Toxic substances emissions are one of the limiting factors in the process of optimization. This analysis can be considered as the first step towards defining optimal operating parameters of the pilot-plasma facility for waste treatment from the ecological and economical aspects.

AB  - The paper presents results of experimental investigation performed in order to examine kinetics of loose biomass combustion in vertical tube reactor. The investigation conducted included continuous measurement of the fuel mass loss rate, with two biomass combustion models (piston and batch model) proposed, each relying on appropriate theoretical postulates. Results obtained indicated that piston combustion model had shown better agreement between theoretical and experimental data and was therefore used to further analyse effects of excess-air on the combustion kinetics, as well as associated effects of flue gas recirculation. Recirculation of cold flue gases is used to lower peak temperature inside the furnace, as well as to reduce a zone where ash melting problems may potentially occur. During the investigation performed, effects of flue gas recirculation on the combustion process were simulated by simultaneously injecting nitrogen and air flows into the furnace. This was deemed appropriate to simulate real-life conditions prevailing in the furnace with gas recirculation. Experiments were conducted on specially designed and constructed apparatus that enabled kinetic parameters to be determined for the combustion of different types of biomass. Results obtained have indicated that quantity of air affects kinetics of biomass combustion and that increased recirculation leads to reduced biomass reaction rate. The same conclusion was reached based on the results of experiments conducted with two different types of agro-biomass, namely wheat straw and corn stalks, which are most commonly used for energy generation. Results achieved are deemed particularly important when it comes to design of new plants that utilize cigarette type combustion system, but also for development of numerical models used to simulate combustion of biomass bales, with special emphasis placed on the impact of recirculation gases on the combustion kinetics. © 2018 Energy Institute

AB  - In order to study the combustion process of baled biomass several experimental facility was built. During the investigations for several years certain problems were founded. In the paper presented the results of these investigations that were carried out in real and laboratory conditions. Investigation of the influence of bale quality to the process of biomass combustion shows that careful bales choosing avoid many problems in the boiler operation. Performed experimental investigation has demonstrated that the use of additives allows for safe and reliable biomass combustion, even of biomass varieties characterized by low ash melting temperature, such as wheat straw and maize. Investigation of the characteristics of biomass exposed to the process of leaching and washing indicate that the washing of wheat straw affects the chemical composition of the ash, which is reflected in the increase the ash melting temperatures. The results of the performed tests in experimental furnace in many ways help to better behavior the process of baled biomass combustion in order to avoid the exploitation problems of the use of agricultural biomass. Also, the results of this research will be used in designing and construction the new plants that will burn agricultural baled biomass. © 2019 ETA-Florence Renewable Energies.

AB  - This paper presents numerical and experimental investigations of complex and interrelated physical and chemical phenomena that occur during combustion of baled soybean residue in the furnace with the cigarette type of combustion. The result of comprehensive research is reactive flow model of biomass combustion inside furnace. Model is described by set of PDE which define momentum, heat and mass transfer processes in porous and fluid system. The main aim of developed CFD model is numerical simulation of combustion process inside the cigarette furnace. It is also used to provide deeper insight in complex processes occurring during biomass combustion. Verification of proposed numerical model was performed through comprehensive experimental tests on the experimental-industrial plant of 1.5 MW boiler for heating the greenhouses in the Agricultural Corporation in Belgrade. The tests included measurement of flow rate and air and flue gas temperature input and output values on the furnace that are taken as the boundary conditions of the developed model. Comparison of the experimental results shows satisfactory agreement with numerical results (the maximum relative deviation of calculation and measurement temperatures are 10-45%), therefore the developed mathematical model could be used to analyse the effects of structural and parametric (fuel composition, power rate, air excess etc.) changes of the facility, from the standpoint of energy efficiency and ecology.

AB  - Harmonization of environmental protection and the growing energy needs of modern society promote the biomass application as a replacement for fossil fuels and a viable option to mitigate the greenhouse gas emissions. For domestic conditions this is particularly important as more than 60% of renewables belongs to biomass. Beside numerous benefits of using biomass for energy purposes, there are certain drawbacks, one of which is a possible high emission of NOx during the combustion of these fuels. The paper presents the results of the experiments with multiple biomass types (soybean straw, cornstalk, grain biomass, sunflower oil, glycerin and paper sludge), using different combustion technologies (fluidized bed and cigarette combustion), with emphasis on the emission of NOx in the exhaust gas. A presentation of the experimental installations is given, as well as an evaluation of the effects of the fuel composition, combustion regimes and technology on the NOx emissions. As the biomass combustion took place at temperatures low enough that thermal and prompt NOx can be neglected, the conclusion is the emissions of nitrogen oxides primarily depend on the biomass composition - it is increasing with the increase of the nitrogen content, and decreases with the increase of the char content which provides catalytic surface for NOx reduction by CO.

AB  - The paper presents a 2-D CFD model of liquid fuel combustion in bubbling fluidized bed. The numerical procedure is based on the two-fluid Euler-Euler approach, where the velocity field of the gas and particles are modeled in analogy to the kinetic gas theory. The model is taking into account also the third liquid phase, as well as its interaction with the solid and gas phase. The proposed numerical model comprise energy equations for all three phases, as well as the transport equations of chemical components with source terms originated from the component conversion. In the frame of the proposed model, user sub-models were developed for heterogenic fluidized bed combustion of liquid fuels, with or without water. The results of the calculation were compared with experiments on a pilot-facility (power up to 100 kW), combusting, among other fuels, oil. The temperature profiles along the combustion chamber were compared for the two basic cases: combustion with or without water. On the basis of numerical experiments, influence of the fluid-dynamic characteristics of the fluidized bed on the combustion efficiency was analyzed, as well as the influence of the fuel characteristics (reactivity, water content) on the intensive combustion zone.

AB  - The paper presents results of experimental and numerical investigation addressing combustion of baled agricultural biomass in a 50 kW experimental furnace equipped with cigar burners. Experiments performed included measurements of all parameters deemed important for mass and energy balance, as well as parameters defining quality of the combustion process. Experimental results were compared with results of numerical simulations performed with previously developed CFD model. The model takes into account complex thermo mechanical combustion processes occurring in a porous layer of biomass bales and the surrounding fluid. The combustion process and the corresponding model were deemed stationary. Comparison of experimental and numerical results obtained through research presented in this paper showed satisfactory correspondence, leading to the conclusion that the model developed could be used for analysis of different effects associated with variations in process parameters and/or structural modifications in industrial biomass facilities. Mathematical model developed was also utilized to examine the impact of gas re-circulation on maximum temperatures in the combustion chamber. Gas re-circulation was found to have positive effect on the reduction of maximum temperature in the combustion chamber, as well as on the reduction of maximum temperature zone in the chamber. The conclusions made provided valuable inputs towards prevention of biomass ash sintering, which occurs at higher temperatures and negatively affects biomass combustion process.

AB  - Modeling of transport phenomena in materials with porous bed features requires thermophysical properties, such as porosity, permeability and thermal conductivity be known. The paper presents experimental data obtained in the course of investigation focused on analysis of stagnant thermal conductivity of biomass. Experiments were conducted using a custom designed and constructed experimental setup and implementing original experimental procedure. Results obtained enabled stagnant thermal conductivity of biomass to be determined for different biomass porosity values. Analysis of the experimental data enabled functional dependence of stagnant thermal conductivity on porosity to be determined, with porosity varied in a range 0.50-0.85. Results obtained indicate that reduced bed porosity, down to the value of 0.65, causes stagnant thermal conductivity of the bed to be reduced. Further porosity reduction, below the value of 0.65, results in increased stagnant thermal conductivity of the bed. Experimental procedure developed shall be useful for gathering experimental data on different materials planned to be analyzed when examining transport phenomena occurring during combustion of biomass bales. In addition, data to be acquired shall be helpful in modeling the transport phenomena associated with combustion in porous beds. (C) 2015 Elsevier Ltd. All rights reserved.

AB  - This paper deals with the numerical simulation of liquid fuel combustion in a fluidized reactor using two-fluid Eulerian-Eulerian fluidized bed modeling incorporating the kinetic theory of granular flow (KTGF) to gas and solid phase flow prediction. The comprehensive model of the complex processes in a fluidized combustion chamber incorporates, besides the prediction of gas and particular phase velocity fields, the energy equations for the gas and solid phase and the transport equations of conservation of chemical species with the source terms due to the conversion of chemical components. Numerical experiments showed that the coefficients in the model of inter-phase interaction drag force have a significant effect, and they have to be adjusted for each regime of fluidization. A series of numerical experiments was performed with combustion of liquid fuels in a fluidized bed (FB), with and without significant water content. The given estimations were related to the unsteady state, and the modeled period corresponds to the passing time of the flow through the reactor column. The numerical experiments were conducted to examine the impact of the water content in a liquid fuel on the global FB combustion kinetics.
