Abstract
In the present paper, results of investigations of Polycyclic Aromatic Hydrocarbons (PAHs) in granulometric fractions of dust, emitted from 9 hard coal fired mechanic stoker boilers, are presented. Exhaust gases were sampled with a Mark III dust sampler. Extracts derived from the dust fractions were analysed by using Gas Chromatography (GC). The 16 PAHs, total PAHs and equivalent benzo(a)pyrene (B(a)P) were determined. Results of measurements averaged over all examined boilers are presented as concentrations, contents and contributions of investigated hydrocarbons to particular standardised fractions of dust classified according to particle sizes. Distributions of PAHs and their profiles in the dust fractions were determined. The emission factors for B(a)P and Toxic Equivalent B(a)P (TE B(a)P) were determined and proved to be several times higher than for pulverised fuel fired boilers. In the emitted dust, 73% of the total PAHs most hazardous to human health are comprised in PM1.
