Nox and SO2 emission factors for Serbian lignite Kolubara
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2012)
Emission factors are widely accepted tool for estimation of various pollutants emissions in USA and EU. Validity of emission factors is strongly related to experimental data on which they are based. This paper is a result ...
Biomass gasification with preheated air: Energy and exergy analysis
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2012)
Due to the irreversibilities that occur during biomass gasification, gasifiers are usually the least efficient units in the systems for production of heat, electricity, or other biofuels. Internal thermal energy exchange ...
Mixtures of bioethanol and gasoline as a fuel for SI engines
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2009)
The importance of alternative fuels, especially bioethanol and biodiesel, rises due to the limited oil sources, secure supply, prices changes, and environment pollution. Bioethanol is an alternative fuel which will be ...
Some subtleties concerning fluid flow and turbulence modeling in 4-valve engines
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2011)
In this paper some results concerning the structure and evolution of fluid flow pattern during induction and compression in 4- valve engines with tilted valves were presented. Results were obtained by dint of multidimensional ...
Criteria selection for the assessment of Serbian lignites tendency to form deposits on power boilers heat transfer surfaces
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2009)
Based on investigations of ash deposit formation, semi-empirical indicators for slagging and fouling, based on ash chemical composition and its fusion temperature, have been determined. These criteria-indicators, in suggested ...
Optimization of the triple-pressure combined cycle power plant
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2012)
The aim of this work was to develop a new system for optimization of parameters for combined cycle power plants (CCGT) with triple-pressure heat recovery steam generator (HRSG). Thermodynamic and thermoeconomic optimizations ...
The possibilities for measurement and characterization of diesel engine fine particles: A review
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2011)
This review paper considers possible instrumentation for diesel engine fine particles exhaust emission evaluation. The modern diesel engines have extremely low particles emission almost at the level of measurement error ...
A study on the grindability of Serbian coals
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2011)
Thermal power plants in the Republic of Serbia are making considerable efforts and even more considerable investments, not only to maintain electricity production at maximum design levels, but even to additionally increase ...
Thermomechanical modelling the resistance welding of PbSb alloy
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2010)
The analytical modelling of the PbSb alloy resistance spot welding process has been developed on the basis of mathematical analysis of thermomechanical conservation laws. The numerical solution of partial differential ...
Waste heat potentials in the drying section of the paper machine in Umka Cardboard Mill
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2011)
This paper deals with methods for calculation of potentials of waste heat generated in paper/board production process. For that purpose, the material and heat balance of the cardboard machine at Umka Cardboard Mill has ...
