Determination of PM10 and deposited dust dispersion on the settlementareas from Aksa Göynük coal (lignite) fueled thermal power plant

Özet

With the growing population and rapidly developing industrialization in Turkey, energy demand is also in-creasing. The majority of the energy is produced using imported products, which increase the current accountdeficit in Turkey. The use of coal from domestic sources are encouraged for economic reasons. One of the coal(lignite) fueled thermal power plants established for this purpose is operating in the province of Bolu Göynük. Inorder to determine the environmental effect of the plant on the settlement areas in the area, air quality mon-itoring studies have been conducted. In the study, the periodic PM10and deposited dust parameters have beenmonitored monthly at four points between 2013 and 2019, including before and after installation of the plant. Asa result of the study; the mean PM10measurement were obtained as 36.48 ± 0.73; 37.61 ± 0.75;42.70 ± 0.85 and 38.72 ± 0.77μg/m3for four points. Meanwhile, the mean values of the deposited dust werefound as 70.81 ± 2.12; 35.55 ± 1.07; 79.50 ± 2.39 and 29.38 ± 0.88 mg/m2/day. Despite the providingcurrent limit values of the dust parameter for power plant where the electrostatic precipitator (ESP)filter andflue gas desulfurization (FGD) systems are applied, it is observed that the dust emissions from activities such ascoal extraction, crushing, sieving and ash storage in the area show different cases depending on meteorologicalconditions.
