AB  - Institut „Vinča“ se greje iz centralne kotlarnice toplom vodom u primarnom krugu. U kotlarnici su instalisana četiri mazutna vrelovodna blok kotla ukupne snage od 9,65 MW. To je veoma zastareo sistem grejanja koji ima niz nedostataka. Međutim, promena tog sistema i eventualno prelazak na dvostepeni (primarni i sekundarni vrelovodni/toplovodni krugovi sa ugradnjom podstanica) je veoma skup poduhvat i u ovom trenutku se ne razmatra. U radu je sagledana mogućnost supstitucije postojećeg goriva (mazut) biomasom. Za tu svrhu bi se morao izgraditi novi kotao koji će sagorevati biomasu. Analiza sprovedena u ovom radu je pokazala da li je i u kojoj meri to isplativo, ekološki prihvatlјivo, energetski efikasnije, kao i koliko je naučno istraživački korisno. U radu je prikazana i analiza angažovane snage kotlarnice za dve izabrane grejne sezone, što može pomoći u određivanju potrebne instalisane snage novog kotla na biomasu.

AB  - "Vinca" Institute is heated from a central boiler station using a hot water in the primary circuit. In the boiler room a four heavy fuel oil hot water block boilers were installed with total capacity of 9.65 MW. It is very outdated heating system which has a number of disadvantages. However, the change of the system and eventually change to a two-stage (primary and secondary hot water/hot water circuits with installation of substations) is a very expensive proposition and at this time is not considered. In the paper is investigated the possibilities of substitution of the existing fuel (heavy fuel oil) with biomass. For this purposes a new boiler which will burn biomass would be built.The analysis conducted in this paper has shown whether and to what extent is cost-effective, environmentally friendly, energy efficient, and how is useful from scientific and research point of view. In the paper has been presented the analysis for two selected heating season, which may help in determining the installed capacity of the new biomass boiler. Also, in the paper are presented a complete logistics system required for implementation of biomass usage as a fuel in heating system of the Vinca Institute.

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  - Za sagorevanje biomase iz poljoprivredne proizvodnje moguće je koristiti više tehnologija. Jedna od njih, koja je u potpunosti razvijena kod nas, je cigaretno sagorevanje celih bala biomase. Za uspešno sagorevanje biomase u obliku bala neophodno je njihovo kontinualno i automatsko doziranje. U radu je prikazan razvijen uređaj za doziranje koji obezbeđuje kontinualno, kontrolisano i potpuno sagorevanje balirane biomase iz poljoprivredne proizvodnje. Biomasa je u formi malih bala koje su paralelopipednog oblika dimenzija 40x50x80 cm. Pod malim balama podrazumevaju se one sa kojima se, zbog njihove težine od 12-15 kg uglavnom ručno manipuliše, što znači da se ne zahteva mehanizovano upravljanje balama. Kontinualno doziranje biomase ostvaruje se uvođenjem bala biomase iz spremišta bala, u koji se može smestiti više bala biomase poređanih jedna iznad druge, u uvodni kanal korišćenjem klip cilindara koji služe za držanje bala, i daljim kontinualnim doziranjem bala u ložište kotla korišćenjem zupčaste letve koja se pokreće uz pomoć elektromotora. Proizvedena toplota od sagorevanja biomase odvodi se do korisnika ili se skladišti u odgovarajućem akumulatoru toplote.
AB  - For burning of biomass obtained from agricultural production it is possible to use several technologies. One of them, fully developed in this country, isa cigarette burning of whole biomass bales. For successful burning of biomass in the form of bales, it is necessary to ensure their continuous and automatic dosing. The paper includes a presentation of a dosing unit or device that enables continuous, controlled and full burning of baled biomass from agricultural production. Biomass is in the form of small bales of parallelepiped shape, having the following dimensions: 40x50x80 cm. Small bales are those that are handled manually, due to their weight rangingfrom 12 to 15 kg, which means that there is no requirement for mechanized control of bales. Continuous dosing of biomass is obtained by feeding biomass bales from the storage (biomass yard), in which it is possible to put several biomass bales one above the other, into the introduction channel by using piston cylinders that serve for bale holding, and by further continuous dosing of bales to the firing of the boiler by using the gear batten that is driven by an electromotor. Heat produced from biomass burning may be delivered to users or may be stored in the appropriate heat storage.

Jedna od njih, koja je u potpunosti razvijena kod nas, je cigaretno sagorevanje celih bala biomase. Za uspešno sagorevanje biomase u obliku bala neophodno je njihovo kontinualno i automatsko doziranje. U radu je prikazan razvijen uređaj za doziranje koji obezbeđuje kontinualno, kontrolisano i potpuno sagorevanje balirane biomase iz poljoprivredne proizvodnje. Biomasa je u formi malih bala koje su paralelopipednog oblika dimenzija 40x50x80 cm. Pod malim balama podrazumevaju se one sa kojima se, zbog njihove težine od 12-15 kg uglavnom ručno manipuliše, što znači da se ne zahteva mehanizovano upravljanje balama. Kontinualno doziranje biomase ostvaruje se uvođenjem bala biomase iz spremišta bala, u koji se može smestiti više bala biomase poređanih jedna iznad druge, u uvodni kanal korišćenjem klip cilindara koji služe za držanje bala, i daljim kontinualnim doziranjem bala u ložište kotla korišćenjem zupčaste letve koja se pokreće uz pomoć elektromotora. Proizvedena toplota od sagorevanja biomase odvodi se do korisnika ili se skladišti u odgovarajućem akumulatoru toplote., For burning of biomass obtained from agricultural production it is possible to use several technologies. One of them, fully developed in this country, isa cigarette burning of whole biomass bales. For successful burning of biomass in the form of bales, it is necessary to ensure their continuous and automatic dosing. The paper includes a presentation of a dosing unit or device that enables continuous, controlled and full burning of baled biomass from agricultural production. Biomass is in the form of small bales of parallelepiped shape, having the following dimensions: 40x50x80 cm. Small bales are those that are handled manually, due to their weight rangingfrom 12 to 15 kg, which means that there is no requirement for mechanized control of bales. Continuous dosing of biomass is obtained by feeding biomass bales from the storage (biomass yard), in which it is possible to put several biomass bales one above the other, into the introduction channel by using piston cylinders that serve for bale holding, and by further continuous dosing of bales to the firing of the boiler by using the gear batten that is driven by an electromotor. Heat produced from biomass burning may be delivered to users or may be stored in the appropriate heat storage.",

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.

AB  - Performed investigation of pulverized fuel combustion in swirl flows has shown that there are two important groups of influential parameters: fuel and burner characteristics. The most important conclusion of these investigations is that each type of fuel needs a defined burner for its combustion and concrete operating parameters for its optimal work. Optimal operating parameters can be determined only by performing the appropriate experiments. Selection of optimal swirl burner design is dependent on energy loss which is used for air transport through burner. Increasing of swirl intensity is convenient for fuel ignition and flame stability, but energy loss for air transport increases, too. Swirl economy is estimated using hydraulic resistance parameter which represents energy loss due to swirling. In the paper are presented the methods and experimental data of hydraulic resistance determination for three laboratory models of swirl burners for pulverized fuel combustion. In the tangential burner the swirling is accomplished by tangential inflow of secondary air and fuel/air mixture. Axial-blade burner of type 1 enables swirling by a set of 18 blades. Axial-blade burner of type 2 is with a central lead of gas and coaxial lead of fuel/air mixture, primary air and recirculating gases. In movable swirl block burner the secondary air swirling is enabled by 8 stationary and 8 movable blocks fixed at movable and stationary plate. (C) 2012 Published by Elsevier Ltd.

AB  - Za sagorevanje biomase iz poljoprivredne proizvodnje moguće je koristiti više tehnologija, od kojih je cigaretno sagorevanje celih bala u potpunosti razvijeno kod nas. Osnovne prednosti ove tehnologije su da nema promene forme biomase, sopstvena potrošnja električne energije je minimalna a smanjeni su investicioni i eksploatacioni troškovi. Za uspešno sagorevanje biomase u obliku bala neophodno je njihovo kontinualno i automatsko doziranje. U radu je prikazan razvijen uređaj za doziranje koji obezbeđuje kontinualno, kontrolisano i potpuno sagorevanje balirane biomase. Biomasa je u formi velikih bala koje mogu biti paralelopipednog oblika dimenzija 0,7x1,2x2,0 m ili valjkastog oblika dimenzija ø1,80x1,20 m, sa kojima se zbog njihove težine ne može ručno manipulisati. Ceo sistem za doziranje bala sastoji se od sledećih segmenata: prihvat bala, hidraulični dozator, vodom hlađeni uvodnik bala, šiber za zatvaranje vodom hlađenog uvodnika bala, sistem za doziranje bala u trenucima zaustavljanja rada kotla i protivpožarni sistem. Sistem je praktično proveren na vodogrejnom kotlu toplotne snage 1,5 MW koji koristi baliranu biomasu i duže vremena je u redovnoj upotrebi.
AB  - For  combustion  of  biomass  from  agricultural  production  can  be  used  several  technologies,  including  a  cigarette  burning  whole  bales  in  the  fully  developed  by  us.  Main  advantages  of  this  technology  are  that  there  is  no  change  in  the  form  of  biomass,  net  energy  consumption  is  reduced  by  a  minimum  investment  and  operating  costs.  For  the  successful  combustion  of  biomass  in  the  form  of  bales  it  is  necessary  their  continuous  and  automated  feeding.  The  paper  presents  developed  device  for  bales  feeding  that  provides  continuous,  controlled and complete combustion of baled biomass. Biomass is in the form of big bales that can  be  parallelepiped  shaped  with  dimensions  0.7x1,  2x2,0  m  or  cylindrical  shape  with  dimensions  ø1,80x1,20  m,  with  which  their  weight  can  not  be  manually  manipulated.  The  entire  feeding  system  bundle  includes  the  following  segments:  bales  acceptance,  hydraulic  feeder,  water-cooled  bales  channel,  closing  segment  of  water-cooled  bales  channel,  bale  feeding system in times of stopping operation of the boiler and fire alarm system. The system was  practical  tested  on  a  boiler  with  heat  power  of  1.5  MW  using  baled  biomass  that  is  in  longer period of time in regular use.

AB  - At the Vinca Institute of Nuclear Sciences, the Laboratory for Thermal Engineering and Energy has for the last few year made a lot of efforts in promoting the usage of residues of agricultural production. The method concerned is cigarette burning biomass combustion technology, which was evaluated by the European Union as very suitable for that purpose. The advantages of this type of combustion are minimal electricity consumption for fuel preparation, the meeting of ecological criteria, lower exploitation and investment costs and possibilities of operation process automation. For that purpose, a boiler of 70 kW heat power for small bale biomass combustion was developed. The producers of small bales are practically all agricultural workers. The boiler was designed for using small square bales with dimensions 40x50x70 cm. The results of the baled biomass combustion investigation in the above-mentioned boiler are presented in the paper. The investigations were performed with several types of baled feeders (shortened, inclined and horizontal). All the investigations were followed with adequate temperature and flue gas composition measurements.

The powders were doped and co-doped with rare earth cations in the concentration range 0 :5 x :! 0.25. The results showed that by doping with one or more dopants simultaneously in the mentioned concentration range solid solutions with host ceria were formed. Differences in the properties of nanopowders obtained by the two methods were discussed. Defect model introducing anion vacancy radius was applied to calculate lattice parameters of single doped and co-doped ceria nanosized solid solutions.

AB  - Glycine/nitrate method was modified and applied to synthesize ceria solid solutions doped with rare earth cations and yttrium (Gd, Sm, Nd, Y) in the concentration range 0 LT = x LT = 0.25. The modification of glycine nitrate process was performed by substituting a portion of Ce-nitrate with the less expensive Ce-acetate. Nanometric size powder particles were obtained. Powder properties such as specific surface area, crystallite and particle size, dopants content and lattice parameters have been studied. The results showed that the dopants used in the mentioned concentration range formed solid solutions with host ceria. Defect model introducing anion vacancy radius can be applied to calculate lattice parameters and theoretical densities of doped and four-fold co-doped ceria nanosized solid solutions.

AB  - A nano-sized CeO2 powder was synthesized by a modified glycine nitrate process (MGNP). The synthesized powder was characterized by X-ray diffraction (XRD), the Brunauer Emmett Teller (BET) method, and transmission electron microscopy (TEM). The lattice parameter and crystallite size were determined by the Rietveld refinement of X-ray diffraction patterns. The shrinkage kinetics of the green body was continuously monitored in air and in oxygen atmospheres using a high temperature dilatometer up to 1500 degrees C. During the high temperature sintering in redox reaction occurred (Ce4+ was partially reduced to Ce3+ and oxygen gas was released). The redox reaction influenced the sintering behaviour of CeO2, resulting in a decrease in density. On the basis of shrinkage kinetics data in oxygen atmosphere a master sintering curve for CeO2 was constructed. Using the concept of the master sintering curve, the densification behaviour in oxygen atmosphere was successfully predicted from early to final stages of sintering. During sintering of CeO2 at lower temperature in air atmosphere a significant contribution of the surface diffusion was observed.

It is shown that mirror brightness of these zinc deposits is associated with flat and mutually parallel hexagonal zinc crystals which are smooth at the atomic level. The mechanism of zinc electrodeposition with these additives is examined by the use of a possibility of STM software measurements based on root-mean-square roughness analysis of metal surfaces and known as scaling analysis. It is proposed that the zinc growth in the presence of these additives follows the Edwards-Wilkinson model.

AB  - One of the methods for powder synthesis that is both cost and time effective is the self-propagating room temperature synthesis. We applied this method to synthesize rare earth doped ceria nanopowders. Since they exhibit very high ionic conductivity at intermediate temperatures these compositions are attractive for a new generation of nanostructured ceramics applicable in solid oxide fuel cells as electrolytes. In this paper we paid our attention to the reaction based on methathetical pathway, whereby solid solution nanopowders of rare earth elements with ceria were obtained at room temperature. Compositions of Ce1-xRexO2-delta (Re = Y, Nd) were synthesized with x ranging from 0 to 0.20. The reaction course is discussed and the properties of the obtained powders are presented.

AB  - Ceria based solid solutions are promising ceramic electrolytes for SOFC which will be able to function at intermediate temperatures. In accordance with common trends to decrease the production and operating costs of new generation of SOFC materials the reaction based on metathetical pathway is described, whereby solid solution powders of rare earth doped ceria in the nanoscale range were obtained at room temperature. By simple hand mixing of reactants the reaction was enhanced, propagating afterwards by itself. Nanometric ceria powders doped with Y or Nd, as well as co doped with both cations were synthesized. Composition of Ce1-xMexO2-y ranged from x =0-0.25. The reaction course is described in detail and the properties of the obtained powders are presented. (c) 2005 Elsevier B.V. All rights reserved.

AB  - The influence of mechanical activation of the mixture basic MgCO3-amorphous SiO2 on reaction of forsterite formation was studied with and without the presence of fluorine ion. Beneficial influence of mechanical activation on the reaction in the mixture without fluorine ion is a consequence of the change of the granulometry during the intense milling. Mechanical activation in the presence of fluorine ion affects the mechanism of forsterite formation via different compounds from the humite group. With non-activated mixture dominant transition phase is hondrodite, while with activated mixture, clinohumite is the transition compound in the process of formation of end reaction products. Fluorine ion is released from the system by hydrolysis. (C) 2001 Elsevier Science S.A. All rights reserved.

AB  - The preferred orientations of copper deposits obtained from acid sulfate solutions were examined. Mat deposits obtained in the absence of the additives and in the presence of disodium 2-naphthol-3,6-disulfonic acid possessed a weak (200) and (220) preferred orientation, respectively. Bright deposit obtained with thiourea only had (111)orientation, while the deposit obtained with mixture thiourea/disodium 2-naphthol-3,6-disulfonic acid exhibited predominant (111) orientation. Bright copper deposits had the preferred orientation in the closest-packed plane of f.c.c. copper lattice, i.e. in the (111)plane.
