DECOMPOSITION OF ORGANOHALOGEN COMPOUNDS IN MUNICIPAL SOLID-WASTE INCINERATION PLANTS .2. COCOMBUSTION OF CFC CONTAINING POLYURETHANE FOAMS

The thermal decomposition of foams containing chlorofluorocarbon 11 (C FC-11) was studied both in the KfK test facility TAMARA and in a munic ipal solid waste incinerator (MSWI). At technical feasible PUF feeds a nd typical combustion temperature the CFC-11 destruction is 99.999 % i n TAMARA and 99.998 % in the MSWI. The CFC-11 emission exceeds only sl ightly the background level in ambient air. Up to 50% of the chlorine and fluorine fed in by CFC-11 were released into the flue gas as hydro halogens, which are removed by modern APC systems without problems.
