Abstract:
Polycyclic aromatic hydrocarbons (PAHs) are emitted during phases of incomplete combustion and are considered particularly harmful to the human health. Benzo(a)pyrene (BaP) as a representative of PAHs is restricted by the European Union to an annual average value of 1°ng/m³, which is significantly exceeded during heating seasons in various regions. Thus a measurement method for BaP in flue gas for variable situations in field measurements was developed. Application in different locations and moderate costs for analyses were the main criteria for the development. This method is includes an in-stack testing probe which is used to take a partial current of the flue gas isokinetically. After a dilution step (1:10), the stream is led through a quartz fibre filter. At validation measurements it was shown that BaP separation with filter only and no additional adsorber is sufficient to obtain representative results at different flue gas quality in terms of complete combustion. This is a fundamental step for subsequent measurements of flue gas from different biomass combustion technologies (automatically and manually fed).
