Title of the articleResearch of processes of burning of solid municipal waste by numerical method
Abstract.When developing effective methods of processing of solid municipal waste (SMW) the great value has forecasting of structure of products of processing of SMW and properties of high-temperature processes. It is connected, in particular, by that the plants using thermal methods of neutralization of solid industrial and household waste, can be sources of emissions of extremely toxic substances, in particular, polychlorinated Dibenzo-p-dioxine (PCDD) and polychlorinated Dibenzofurane (PCDF). Formation of these substances decides as availability of dioxine directly in the thermal reactor, and as a result of reactions of organic carbon on molecular chlorine, hydrochloric acid or on the chlorine which is a part of organic compounds. In low-temperature zones of a path of combustion gases (T=550…700 K) in the presence of catalysts in the form of metal surfaces of a path, surfaces of particles of flying ashes additional synthesis of dioxine is possible. Measurement of concentration of various products of combustion on an installation path for burning of solid municipal waste indicates formation of more and more chlorinated substances, when sampling in the direction from an exit from the combustion chamber to an output pipe. From here it is possible to draw a conclusion that the majority of dioxine is formed consistently with process of burning or in heat exchangers, and also cleaning and control installations. The role of the combustion chamber consists in delivery of molecules – harbingers of formation of dioxine. Defining conditions for minimization of processes of formation of these harbingers, it is possible to limit to that and emission of dioxine. As such harbingers aromatic hydrocarbons, benzene chlorides and chlorophenols can be.
Keywords.Solid municipal waste, thermal utilization, toxic gaseous substances, dioxine.
