Ecological risks of toxic substances combustion

Abstract

Experimental and theoretical results of the authors and other Russian and foreign scientists on analysis of toxic substances formation from combustion of chemical compounds are examined. The theoretical approach of the authors has a general character, allowing to determine concentration limits of substances formed by high temperature combustion and can be applied to a wide set of utilized toxic substances. Special attention is given to the case of combustion of chlorine-containing substances, during which formation of polychlorinated aromatic hydrocarbons (dibenzo-p-dioxines, dibenzo-furans, etc.) is possible. The report shows that a correctly organized combustion process, with fast water cooling of combustion products in particular, the contents of dioxins and furans in combustion products can be reduced 8-10 times. © 2006 Springer.
