Abstract

Size distribution of particulate matter (PM) emitted from coal combustion in residential furnaces as well as emission of Hg, Zn, Pb and Cu were investigated. The metals emission was characterised by partition factors K. The factor expresses the distribution of metal streams between the feed coal and its combustion products emitted to the atmosphere. The values of factors K for Zn, Pb and Cu were 0.59, 0.33 and 0.34 respectively; the relevant variance coefficients were 37, 46 and 44%. Much better variance coefficient of factor K (17%) appeared in the case of mercury. It was found that 52% of Hg in feed coal was emitted to the air in gaseous form. Particulate matter emission from 7 coal combustion sources was investigated and fine particles were found as the main fraction. About 76% of PM were emitted as the size fractions up to 12 μm. The share of size fractions between 12-29 μm was 9%. It means that the impact of PM emission from residential furnaces is not of local scale but the particles containing heavy metals can be transported on long distances in the atmosphere.
