Refuse Composition And flue-Gas Analyses from Mun;c;pal Incinerators

An alyses of the components of municipal refuse were assembled, from which an average· composite analysis was calculated. The analyses of the flue and stack gases from 18 municipal incin erators were also tabu­ lated and plotted. A marked difference was n oted be­ tween the analyses of the stack gases and those to be expected from the combustion of the composite refuse. Much of the difference can be accounted for by the carbon loss in the residue and oxidation of metallics. Suggestion s for future in vestigations in clude new refuse and residue analyses, and chemical studies on the inter­ action of spray water and fly ash with nue gas. A n ew formula is presented for correcting stack-gas dust load­ ings to 50 per cent excess air.
