AB  - The pulverized coal-fired furnaces are expected to use co-firing withbiomass for environmental reasons. Although the non-uniform ash depositsare formed on the furnace walls, the uniform deposits could be used for theanalysis of the furnace operation. The objective of this investigation wasdetermination of the uniform deposit thickness, used as a criterion forprediction of the sootblower activation moment in coal-biomass co-firing.The investigation comprised numerical simulations for uniform and nonuniform deposits to find the relative differences for the selected variablesthat were important for the sootblower activation: the mean wall fluxes andflame temperatures. The local thicknesses of the non-uniform deposits weredetermined by the gamma distribution for several mean and standarddeviation values using the inversion method. The thicknesses of the uniformdeposits were considered among the measures of central tendency: mode,mean, and median, of the non-uniform deposits. The mean was expected toprovide the smallest relative differences, while the mode was excluded fromfurther consideration after analysis of its values. The median was found tobe better choice than the mean, as it provided smaller relative differences ofthe selected variables for the thick deposits, which were important for thesootblower activation. The method based on comparison of the uniformdeposits for coal firing and those for the co-firing with biomass wasproposed for the prediction of the sootblower activation moment. Themethod can be used for the selection of the operational regimes for coalbiomass co-firing.

AB  - The comparison of fly ash generated from lignite combustion in a thermal power plant Kolubara A (Veliki Crljeni) and bottom and fly ash from coal waste combustion in a semi-industrial fluidized bed boiler (Vinča) was performed as the function of particle size. The average total concentrations of the 16 EPA priority PAHs in ash fractions are 0.49 mg kg−1 of ash (thermal power plant) and 17.48 mg kg−1 of ash (fluidized bed boiler). The sum of 3- and 4-ring PAHs accounts for more than 93% of overall PAHs concentration, and the most abundant among them is fluoranthene. The portions of PAHs groups defined based on their physico-chemical properties, as obtained from quantitative structure-activity relationship (QSAR) models included in the Vega platform, were determined. These portions, emission factors, and benzo[a]pyrene equivalence concentrations were further on used to estimate the potential environmental impact of ash disposal. The PAHs emission factors are higher compared to values in the air pollutant emission inventory guidebook of the cooperative program for monitoring and evaluation of the long-range transmission of air pollutants in Europe (EMEP/EEA). The overall emission factors of 16 PAHs for combustion of lignite and coal waste are determined to be 0.15 and 249.97 mg kg−1 of fuel, respectively. Based on the ratios of benzo[a]pyrene equivalence concentrations of each ash and correspondent fuel, the disposal of fly ash from the cyclone of fluidized bed boiler represents the highest risk to the environment among tested ashes.

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  - In Laboratory for Thermal Engineering and Energy of Institute Vinca, University of Belgrade, a 2-D CFD modeling procedure of numerical simulation of unconventional liquid fuel combustion in bubbling fluidized bed has been developed. This procedure is based on a two-fluid Euler-Euler approach modeling a fluidized bed with the determination of the velocities field of gas and particulates in two-phase, granular flows, analog to the kinetic theory of gases. This model describes in detail the unsteady motion of gas and solid phases, the formation and movement of bubbles with the combustion process in the fluidized bed, but temperature profiles calculated by the bed height differ to some extent from the experimentally obtained profiles. This discrepancy is probably due to the inability of a two-fluid CFD model to give a realistic simulation of the liquid fuel mixing in a fluidized bed. Therefore, an analytical model has been developed, where one of the basic assumptions is that the particles are mixed in the vertical direction of fluidized bed mainly by the bubble wakes. The proposed zonal type of calculating procedure is based on Davidson and Harrison two-phase model of the bubbling fluidized bed, where fluidized bed is divided into zones within which material and energy balances are set.

The proposed zonal type of calculating procedure is based on Davidson and Harrison two-phase model of the bubbling fluidized bed, where fluidized bed is divided into zones within which material and energy balances are set.",

AB  - Lately, experimental methods and numerical simulations are equally employed for the purpose of developing incineration bubbling fluidized bed (BFB) facilities. The paper presents the results of the 2-D CFD model of liquid fuel combustion in BFB, applied for numerical simulation of a fluidized bed furnace. 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 proposed numerical model comprises energy equations for all three phases (gas, inert fluidized particles, and liquid fuel), as well as the transport equations of chemical components that are participating in the reactions of combustion and devolatilization. The model equations are solved applying a commercial CFD package, whereby the user submodels were developed for heterogenic fluidized bed combustion of liquid fuels and for interphase drag forces for all three phases. The results of temperature field calculation were compared with the experiments, carried out in-house, on a BFB pilot facility. The numerical experiments, based on the proposed mathematical model, have been used for the purposes of analyzing the impacts of various fuel flow rates, and fluidization numbers, on the combustion efficiency and on the temperature fields in the combustion zone.

The paper deals primarily with the chemical reactions of selective noncatalytic reduction of nitrogen monoxide using ammonia as a reagent. Two kinetic models, one rather simplistic, which takes into account only two net reactions and other, more complex with seven chemical reactions, are analyzed.

AB  - Determination of the wall variables (wall emissivities, wall temperatures, and heat fluxes) when the zonal model of radiation is used in numerical simulations of processes inside a pulverized coal-fired furnaces is described. Two methods for determination of the wall variables, i.e., a repeated run of numerical simulation (RRNS) and a temporary correction of the total exchange areas (TCTEA) are compared. Investigation was carried out for three values of the flame total extinction coefficient and four values of the initial wall emissivities. Differences of the wall variables were determined using the arithmetic means (AMs) of the relative differences. The AMs of the relative differences of the wall variables increased with an increase in the flame total extinction coefficient and changed a little with an increase in the initial values of the wall emissivities. For the selected furnace, the smallest differences of the wall variables were obtained for Kt=0.3 m-1 and ew,in=0.7.

AB  - U radu je predložen dvodimenzijski model numeričke simulacije sagorevanja tečnih goriva u flu-idizovanom sloju, koji se zasniva na dvo fluidnom Euler – Euler pristupom modeliranja fluidizovanog sloja uz određivanje polja brzina gasa i čestica u dvofaznim, granularnim tokovima zasnovane na ana-logiji sa kinetičkom teorijom gasova (KTGF). Sveobuhvatan model kompleksnih procesa u fluidizacio-noj komori sagorevanja podrazumeva, pored određivanja polja brzina gasne i čestične faze, inkorpori-ranje energetskih jednačina gasne i čestične faze, kao i transportnih jednačina hemijskih komponenti sa izvornim članovima usled konverzije komponenata.

Urađene su serije numeričkih eksperi-menata sa simulacijom procesa sagorevanja u FS sa i bez značajnog sadržaja vode u gorivu. Proračuni su nestacionarni, a modelirani vremenski period odgovara vremenu za koje gas prođe kroz celu visinu reaktora. Numerički eksperimenti, na osnovu predloženog matematičkog modela, su takođe korišćeni za potrebe analize uticaja različitih snaga pri kojima radi reaktor, kao i različitih stepena fluidizacije, na efikasnost sagorevanja kao i na profile temperatura u zoni sagorevanja.
AB  - A comprehensive 2D numerical model of the bubbled fluidized bed with combustion of liquid fuelsis proposed in the paper. The proposed numerical model is based on the Eulerian–Eulerian granular flow modeling with the kinetic theory of granular flow. The model includes the following basic governing equations: the continuity equations of the solid andgas phase, the momentum conservation equations of the gas and solid phase, the energy equations of gas, and the solid phase and conservation equations for chemical components. The choice of the semi empirical constants of the inter-phase interaction drag force model is significant and these constants must be adjusted for each particular regime of fluidiza-tion. Presented numerical experiments primarily were applied to verification of the assumptions about the impact of water content in a liquid fuel on FB combustion intensity. The numerical experiments, based on the proposed mathematical model, also have been used for the purposes of analyzing the im-pacts of various reactor powers as well as fluidization numbers, on the combustion efficiency and on combustion zone temperature fields

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  - Uprkos činjenici da se upotreba biomase preporučuje sa stanovišta očuvanja životne sredine, usled značajno manje emisije štetnih gasova nego pri sagorevanju uglja, kao najzastupljenijeg domaćeg fosilnog goriva, veoma je značajno praćenje emisije iz dimnih gasova i dobro razumevanje procesa koji utiču na smanjenje koncentracije polutanata. Emisija azotnih oksida (NOx) je jedan od najvećih izazova u tom pogledu. Poznavanje emisije ovih oksida prilikom sagorevanja biomase je neophono radi uspotavljanja korektnih zakonskih normi u pogledu granične emisije i za razvoj što kvalitetnijih tehnologoja za sagorevanje ove vrste goriva. U radu su date izmerene koncentracije azotnih oksida prilikom sagorevanja više vrsta biomase pri stacionarnim uslovima rada eksperimentalnih i demonstraciono - industrijskih postrojenja koja pripadaju dvema različitim tehnologijama: cigaretno sagorevanje balirane slame i sagorevanje u fluidizovanom sloju, kao i sveobuhvatna analiza složenih uticaja na emisiju NOx-a.

abstract = "Uprkos činjenici da se upotreba biomase preporučuje sa stanovišta očuvanja životne sredine, usled značajno manje emisije štetnih gasova nego pri sagorevanju uglja, kao najzastupljenijeg domaćeg fosilnog goriva, veoma je značajno praćenje emisije iz dimnih gasova i dobro razumevanje procesa koji utiču na smanjenje koncentracije polutanata. Emisija azotnih oksida (NOx) je jedan od najvećih izazova u tom pogledu. Poznavanje emisije ovih oksida prilikom sagorevanja biomase je neophono radi uspotavljanja korektnih zakonskih normi u pogledu granične emisije i za razvoj što kvalitetnijih tehnologoja za sagorevanje ove vrste goriva. U radu su date izmerene koncentracije azotnih oksida prilikom sagorevanja više vrsta biomase pri stacionarnim uslovima rada eksperimentalnih i demonstraciono - industrijskih postrojenja koja pripadaju dvema različitim tehnologijama: cigaretno sagorevanje balirane slame i sagorevanje u fluidizovanom sloju, kao i sveobuhvatna analiza složenih uticaja na emisiju NOx-a., Emissions of nitrogen oxidesat the biomass combustion",

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.

AB  - In this paper has been shown improvement of the existing furnace for biomass combustion in the way of improving energy efficiency and meeting environmental protection criteria. One of the main problems during baled biomass combustion process is high CO emission due to incomplete combustion of flue gases. By proper furnace dimensioning that problem can be avoided and also high investment costs can be reduced, since the cost of the furnace is 30-40% of total biomass plant costs. Two-dimensional turbulent flow model with homogeneous chemical reactions has been developed. Turbulent flow is considered using time averaging Navier-Stokes equations that are closed by k-epsilon turbulence model. Calculations based on the proposed models were conducted using commercial CFD package FLUENT. Accuracy of the model has been previously confirmed with experimental data obtained on the existing furnace. Comparative analysis of the results of modeling existing and proposed (improved) furnace has shown lower CO emission (more than 50% less CO emission) at the proposed furnace outlet.

AB  - Biomass is deemed to be the main source of renewable energy in Serbia. Over the past couple of years, considerable efforts have been made to develop a technology which would enable biomass bales of various sizes and shapes to be used for energy production. A hot water boiler with cigarette type of combustion was constructed and used in the experimental investigation of biomass combustion phenomena. During the experiments performed, numerous parameters were measured: flue gas temperature, water temperature at the boiler inlet and outlet, while O-2, CO2, CO, SO2, and NOx content in the flue gas was measured at the boiler outlet. Experiments were performed with biomass feed rate of 0.12 kg/s, mean boiler output of 1.56 MW and mean excess air coefficient of 2.1. During the steady state boiler operation, exhaust gas temperature was measured to be around 150-160 degrees C and obtained CO and NOx emission rates were found to be quite acceptable. In addition, combustion of biomass bales in cigar burners was modelled by the means of appropriate numerical simulation. A good agreement between experimental and numerical results was obtained.

A hot water boiler with cigarette type of combustion was constructed and used in the experimental investigation of biomass combustion phenomena. During the experiments performed, numerous parameters were measured: flue gas temperature, water temperature at the boiler inlet and outlet, while O-2, CO2, CO, SO2, and NOx content in the flue gas was measured at the boiler outlet. Experiments were performed with biomass feed rate of 0.12 kg/s, mean boiler output of 1.56 MW and mean excess air coefficient of 2.1. During the steady state boiler operation, exhaust gas temperature was measured to be around 150-160 degrees C and obtained CO and NOx emission rates were found to be quite acceptable. In addition, combustion of biomass bales in cigar burners was modelled by the means of appropriate numerical simulation. A good agreement between experimental and numerical results was obtained.

AB  - Ekonomajzeri tj. zagrejači vode predstavljaju kotlovsku grejnu površinu koja se koristi za zagrevanje napojne vode u kotlu. Za intenzifikaciju razmene toplote i smanjenje zaprljanja cevi ekonomajzeri preporučuje se korišćenje orebrenih cevi. U radu su prikazani rezultati strujno-termičkih ispitivanja više ekonomajzera toplotne snage od 0,83 do 1,67 MW. Ekonomajzeri su izrađeni od spiralno orebrenih cevi Ø38x3,2 mm postavljenih u šahovskom rasporedu. Visina rebara iznosi 12,5 mm i kontinualno su zavarene za cevi, a njihova debljina iznosi 1 mm. Osnovni cilj ispitivanja bio je da se eksperimentalno odrede performanse ekonomajzera i utvrdi efikasnost njihovog rada. Kako ispitivani kotlovi nisu radili u nominalnom režimu razvijena je metodologija za preračunavanje dobijenih rezultata ispitivanja na nominalni kapacitet kotla. Pri ispitivanjima mereni su protoci i temperature napojne vode i dimnog gasa kao i pad pritiska sa vodene i gasne strane ekonomajzera. Takođe, meren je i sadržaj O2 u dimnim gasovima u cilju preračunavanja rezultata merenja. Dobijeni rezultati pokazali su dobru saglasnost sa projektnim podacima isporučioca opreme.
AB  - Economizers i.e.    water heaters are the boiler heating surface used for heating boiler feed water. For intensification of heat exchange and reducing contamination in economizers it is recommended to use finned tubes. This paper presents the results of thermo-fluid testing of several economizers  with  heat  power  from  0.83  to  1.67 MW.  Economizers  are  made  ofspirally finned tubes Ø38x3, 2 mm with chess set in the schedule. Fins height is 12.5 mm andthey  are continuously welded to the tube, and their thickness is 1 mm. The main objective ofthis  study  was  to  experimentally  determine  performance  of  the  economizers  and  determine their  effectiveness.  Since  the  tested  boilers were  not  working  in  the  nominal  regime,  a methodology for  converting  the  obtained  results  at  nominal  capacity  of  the  boiler  has  been  developed. During  the tests were measured flow rates and temperature of the feed water andflue  gas  as  well  as  the pressure  drop  both on  the  water  and  gas  side  of  economizer.  In addition, O2 content in the flue gases has been measured in order to recalculate measurement results.  The  results  have  shown good  agreement  with  projected  parameters  guaranteed  by  supplier.
