Elimination of toxic gas emissions by MgO soaked expanded clay in waste combustion chambers

Abstract

This paper serves to describe the elimination of toxic gas emissions in coal combustion chambers and activity of expanded clay soaked MgO and other alkali materials such as Lime, Hydrated lime, NaCl, MgCl2 and KCl used in desulfurization. An chemical analysis of ash materials used to characterize the elimination of toxic substances was carried out. As well, the ability of the expanded clay to remove inorganic and organic sulphur and other pollutant substances were determined with their respective process control challenges. In this study, combustion tests of Şırnak asphaltite and different types of Turkish lignites; Kütahya Gediz, Tunçbilek, Soma Kısrakdere were carried out. Lime, Hydrated lime, Magnesia, NaCl, MgCl2 and KCl were used as desulfurizing solid sorbent. The different type of solid sorbents such as Şırnak limestone, marly limestone and claystone, MgO soaked expanded clay use in coal desulfurization were virtually investigated and discussed. Combustion of solid fuels in the presence of expanded clay was managed at low particle sized such as 1-2mm. Expanded clay was examined as an absorbent for a conversion of toxic gas to friendly emissions. It can be a promising waste incineration for the production of electricity from nylon and plastic contaminated municipal wastes because of high activity in the collection and leaching in the toxic gas in the combustion reaction.
