Dioxins And Furans In Cement Kiln Emission Using

Mar 01 2012 Cement kilns are known to emit polychlorinated dibenzopdioxins and furans PCDDFs dioxins but estimates of the amounts and patterns of these emissions vary widely These variations may stem from a combination of factors including the design and operating conditions of the kiln and the fuels and raw materials fed into the kiln
