Abstract

The use of lignite in power generation has led to increasing environmental problems associated not only with gaseous emissions but also with the disposal of ash residues. In particular, the use of low quality coals with high ash content results in huge quantities of both fly and bottom ash to be disposed of. An important problem related to coal ash disposal is the heavy metal content of the residue. In this regard, experimental results of numerous studies indicate that toxic trace metals may leach when fly ash and bottom ash come into contact with water. In this study, fly ash and bottom ash samples obtained from Yeniköy thermal power plant, located on the south-western coast of Turkey, were subjected to toxicity tests, namely, the extraction (EP) and toxicity characteristic leaching (TCLP) procedures of the U.S. Environmental Protection Agency (USEPA) and the Method A extraction procedure of the American Society of Testing and Material (ASTM).

Özet

Linyitle çalışan termik santraller; sadece gas emisyonları nedeniyle değil, kül atıkları ile de önemli çevresel problemler oluşturmaktadırlar. Özellikle düşük kaliteli kömürlerin kullanılması ile yüksek oranda uçucu ve taban külleri atık olarak oluşmaktadır. Kömür küllerinin depolanmasındaki ana problem atıkların ağır metal içerikleridir. Bu bakımdan, birçok deneysel çalışmanın sonucunda uçucu ve taban küllerinin suyla temasında toksik iz metaller özütlenmiştir. Bu çalışmada, Türkiyenin güneybatı kıyısında yeralan Yeniköy termik santrallinden alınan uçucu ve taban küllerinin toksisitesi; USEPA prosedürüne göre çözündürme yöntemi (EP), toksik karakteristik özütleme yöntemi (TCLP) ile ASTM yöntemlerine göre ölçülmüştür. EP ve TCLP analiz sonuçlarına göre yöre atıklarının kurşun ve kadmiyum konsantrasyonları yüksektir. USEPA prensiplerine göre, yöredeki linyit atıkları tehlikeli atık sınıfına girmektedir.
