Abstract
The results of an experimental study of the regularities of the distribution of chlorine between solid and gaseous products during the thermal decomposition of a mixture of chlorine-containing medical waste during their pyrolysis and incineration are presented. It is shown that under thermal action on the chlorine-containing components of the mixture, chlorine is partially converted into gaseous products in the form of Hcl, and partially retained by the coke-ash residue. During pyrolysis, the bulk of chlorine remains in the solid phase. It is concluded that the retention of a significant proportion of chlorine by solid products of thermal decomposition significantly reduces the possibility of dioxin synthesis at the stage of flue gas cooling due to the low content of free chlorine in them.
