| Title of the article | The influence of unburned for thermal utilization of solid municipal waste on formation of toxic gaseous substances |
| Abstract. | The industrial settings, using the thermal methods of rendering of hard industrial and domestic wastes harmless, can be the sources of extras of extraordinarily toxic matters, in particular, Polychlorierte Dibenzo-p-dioxine und Dibenzofurane (PCDD/PCDF). Formation of these matters is determined both the presence of dioxins in hard wastes, acting’s on processing and synthesis of dioxins directly in a thermal reactor due to the reactions of organic carbon with Cl2, HСl or chlorine, entering in the complement of organic compounds. In the low temperature areas of highway of smoke gases (T~550-700 K) in presence catalysts as metallic surfaces of highway, surfaces of particles of volatile ash the additional synthesis of dioxins is possible. For achievement of high ecological efficiency of the thermal settings it is necessary to provide complete oxidization of organic components in a thermal reactor and to translation of all connections of chlorine in mineral chlorides directly in a high temperature area with subsequent deep dust of gases at temperatures more 750 K. It is in this connection necessary to support the temperature of gases in a thermal reactor at level , time of stay of gases in a reactionary area at the indicated temperature no less than 2 seconds, and composition of gas phase must correspond the coefficient of surplus of air in smoke gases, equal ?ox=1,08-1,2. For achievement high level enough temperatures in a reactionary area, complete oxidization of hard domestic and industrial wastes it is possible to use air oxygen-rich. |
