Abstract:
Combustion experiments were carried out in different house heating systems using various fuels. The emission samples and the chimney soot samples were analyzed for polychlorinated dibenzo-p-dioxins/furans (PCDD/F) and polycyclic-aromatic-hydrocarbons (PAH). The PCDD/F-concentrations in fluegases using untreated wood were in the range of 2-25 pg I-TE/m3. The combustion of paper, cartons, painted wood and wood with 2-5% PVC gave PCDD/F-concentrations from 38 to 952 pg I-TE/m3 and 380 to 2,240 ng I-TE/kg (chimney soot). The PAH-concentrations in flue gas were about 30 times higher using an old technology in relation to a new one.
