Abstract

Emission measurement results of from plywood combustion have only been published in one publication. Temperature of exhaust gases, retention time and carbon dioxide and oxygen contents effect strongly on the benzene, toluene and formaldehyde contents of flue gases. The concentrations of these increase rapidly as the CO content of flue gases exceeds 4000 ppmv. Nitrogen oxide emissions of chipboard combustion, published in literature, vary in between 263-765 mg/m3, at O2 content 11%. HCl content of flue gases was 1.0-104 mg/m3, at O2 content 11%. Highest concentration was obtained in a test carried out with a small combustion device, operated with particleboard treated with ammonium chloride hardener. Carbon monoxide concentration varied in the range 45-1165 mg/m3, at O2 content 11%. Even higher concentrations were obtained in the tests carried out with some small combustion devices. Concentrations of dibenzo-p-dioxins (PCDD) and dibenzofurans (PCDF) were 0.019- 4.13 TEQ ng/m3, at O2 level 11%. In many tests the results have been under the limit value 0.1 I-TEQ ng/m3 at O2 level 11%. The limit values for the particle content and particle emissions set in the environmental permits, granted by the regional environment centres, varied in between 50 mg/m3 at O2 level 6% and 400 mg/m3 at O2 level 6%. Particulate emissions limit was 50-100 mg/MJ. There were few restrictions for CO emissions in the environmental permits. They, as well as the particulate emission levels seemed to be tighter for younger plants than for the older ones. In the permits there were set limits for nitrogen oxides and sulphur dioxide only in a couple of cases.
