ABSTRACT

The uncontrolled emissions generated from the combustion of hazardous and municipal solid wastes vary in composition subject to the combustor design and operating conditions and the waste composition. These emissions are of potential concern as they contain:

• Particulate matter (PM). • Polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans

(PCDFs), known collectively as dioxins and furans. • Organic compounds (volatile, semivolatile, and nonvolatile) other than dioxins

and furans, often referred to as products of incomplete combustion (PICs). • Metals that are potentially toxic (e.g., mercury, lead, cadmium). • Acid gases (e.g., hydrogen halides, nitrogen and sulfur oxides).
