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.
