Abstract: The advanced stochastic Monte – Carlo (MC) technique has been developed to predict resulting heat fluxes and / or unknown detailed local temperature profiles within the combustion or furnace chambers for arbitrary initial conditions (design and process parameters). Theoretical background is based upon original combination of following constituents: Hottel’s zone method accompanied by his radiation model of weighted sum of grey gases on emissivity / absorptivity for combustion products while executive procedure being performed by means of application the MC counter operating with dozen thousands of random beams related to each of surface or volume zones. Direct thermal and indirect combustion kinetics characteristics have been used as the checked parameters by verification the MC procedures. Validation of the proposed MC procedures have been carried out by means of comparison of our prediction results by physical and chemical characteristics with respective experimental (measured) and literature data for some types of the industrial furnaces and boilers. Because of strong influence of temperature factors on NOx formation by combustion we have succeeded to calculate the temperature profiles and NOx issue by recirculation the combustion products under operation the boilers of different types. These data confirm an opportunity to predict the pollutants formation values being fairly coincided with measured data.
Brief Biography of the Speaker: Prof. Boris Soroka, Ph.D. (in Industrial Heat Engineering, Institute of Engineering Thermal Physics of National Academy of Sciences, Ukraine (NASU), Kiev, 1968), Doctor of Techn. Sciences (in Metallurgical Heat Engineering, Moscow Technical University of Steel and Alloys, 1987), Professor in Industrial Heat Engineering (1993). After graduating the Nat. Techn. University “Kiev Polytechnical Institute” he joined the Gas Institute, NASU and is working up-to-date, last time his position is Principal Institute’s Scientist. Main areas of his scientific activity are as follows: development of applied combustion theory from the standpoint of chemical thermodynamics and kinetics aspects, along with transportation constituents including radiative and combined heat transfer, the CFD approach to combustion modeling and on numerical simulation, computation of high-temperature processes, environmental aspects and pollutants formation. Applied areas: designs and operation of furnaces, combustion systems, heat exchangers, and various burner facilities, being under protection of 50 his national and international patents. During 20 last years Prof. B. Soroka cooperates constantly with Gas Technology Institute (GTI, Chicago, USA) on low-emission combustion modeling. He participates in fulfillment the international scientific projects with universities and research institutes in EU as well. Prof. B. Soroka is author of more than 350 printed works (Germany, USA, France, Russia, Portugal, Great Britain, Hungary, etc) including more than 20 books and monographs, about 150 papers and presentation have been published in many countries. Main scientific awards: 2006 – awarding with G.F. Proskura’s premium by NASU for individual cycle of the works in combustion ecology and energy efficiency areas, 2007 – awarding as a member of international team with Academician A.V. Lyikov’s Premium, Byelorussian Academy of Sciences, for the cycle of works in area of heat-and –mass transfer in conditions of chemical reactions.
