DGMK Tagungsber., 1997, 9703, (Proceedings ICCS '97, Volume 2) 1087-1090. Air pollution by polycyclic aromatic hydrocarbons (PAH) emissions from fluidized-bed combustion (FBC) of coal were studied from VOC emissions, The PAHs generated in the combustion of a sub-bituminous coal in fluidized-bed combustion were analysed at different temperatures maintaining constant the oxygen excess (20%) and ranging the oxygen excess maintaining the combustion temperature, 550ยฐC. Synchronous fluorescence spectroscopy
(FS) was used to analyse PAH and the main factor affecting PAH emissions from FBC of sub-bituminous coal was found to be the pyrolytic reactions between the radicals emitted and formed at the tap of the combustion reactor. The PAH emissions increased considerably when the percentage of oxygen in the combustion air decreased.
