SR4  Combustão    Titulo: ESTIMATE OF THE DISPERSION OF EMITTED POLLUTANTS IN THE ACTIVITY OF CO-PROCESSING OF INDUSTRIAL RESIDUES   Resumo : ABSTRACT. THE PURPOSE OF THIS PAPER IS TO PRESENT THE RESULTS OF STUDIES OF POLLUTANTS DISPERSION IN THE ATMOSPHERE, ORIGINATING FROM OF THE ACTIVITY OF CO-PROCESSING OF INDUSTRIAL WASTES IN ROTARY KILNS OF CEMENT INDUSTRIES. THE LEVELS OF EMISSIONS OF DANGEROUS POLLUTANTS IN THESE KILNS SHOULD BE MINIMUM, DUE TO THE HIGH DESTRUCTION EFFICIENCIES REACHED IN THIS ACTIVITY, AS WELL AS FOR THE EFFECTIVE CONTROL OF THE RATES OF FEEDING OF THE WASTES, RAW AND FUELS. THE DEMANDS OF THE ENVIRONMENTAL LEGISLATION WITH RELATIONSHIP TO THE LOW CONCENTRATIONS OF HEAVY METALS AND PRODUCTS OF INCOMPLETE COMBUSTION IN THE AIR TURN THE DISPERSION STUDY OF A GREAT VALUE IN THE PRELIMINARY ESTIMATE OF THE ENVIRONMENTAL PROBLEMS OF CONTAMINATION FOR THOSE PRODUCTS. THIS PAPER PRESENTS RESULTS BASED ON THE GAUSSIAN STATISTICAL THEORY, CONSIDERING THE DIFFERENT WAYS OF OBTAINING SOME PARAMETERS, SUCH AS COEFFICIENTS OF HORIZONTAL AND VERTICAL DISPERSION, EFFECTIVE HEIGHT OF THE PLUME, AND STILL CONSIDERING THE DIRECTION OF THE WIND AND THE TOPOLOGY IN THE AREA WHERE A SOURCE OF POLLUTANTS EXISTS. KEYWORDS: ATMOSPHERIC POLLUTION, POLLUTANTS, GAUSSIAN DISPERSION, CO-PROCESSING, POLLUTANTS CONCENTRATION.     Autores : Ramos, Márcio Dimas Silva, Rogério José da     Trabalho Completo :   COBEM99 | Comissão  Organizadora | Palestras | Sessões Técnicas | Autor | Simpósios e Sessões Especiais | Revisores |  Título  dos  Trabalhos | Local
