Tehlikeli Atık Yakma Tesislerinin Duruş Periyodunda Gaz Akışı PCDD/F Emisyonları: İZAYDAŞ İçin Bir Araştırma

Bu çalışmada, Türkiye'nin ilk tehlikeli atık yakma tesisi olan İZAYDAŞ'ın bir duruş periyodundaki PCDD/Fs emisyonları incelenmiştir. Bu amaçla, tesisin bir duruş periyodunun 3 farklı sıcaklık rejimi için atık gaz akımından alınan numuneler gaz ve partikül faz konsantrasyonları için ayrı ayrı analiz edilmiştir. Örneklemeler, her bir sıcaklık rejimi için boiler çıkışı, elektrostatik filtre çıkışı, yıkayıcı çıkışı ve aktif karbon ünitesi çıkışı olmak üzere 4 farklı noktada gerçekleştirilmiştir. Çalışmada elde edilen bulgular, duruş periyodundaki emisyon davranışlarının yalnızca normal işletim periyodu değil işletmeye alma periyotlarındaki davranışlardan da önemli oranda farklı olabildiğini işaret etmektedir. Özetle, tesisin farklı işletim koşullarında farklı yönetim stratejileri uygulamak yöneticiler için bir zorunluluk olarak görünmektedir.

PCDD/F Emissions of Gas Stream at Shutdown Period of Hazardous Waste Incinerators: A Case Study for IZAYDAS

In this study, it was investigated that PCDD/Fs emissions of a shutdown period of the IZAYDAŞ which is the first hazardous waste incinerator of Turkey. For this purpose, the samples of the waste gas stream obtained in three different temperatures of a shutdown period of the facility were analyzed for the gas and the particulate phase concentrations separately. Samplings were obtained from four different points like boiler outlet, electrostatic filter outlet, scrubber outlet, and activated carbon bed outlet, for every temperature regimes. The findings indicated that the emission characteristics of the shutdown periods of the facility could be different from not only the characteristics of the normal operations but also the startup periods of the same facility. In conclusion, to perform different management strategies for different operation conditions of the facility seems like an obligation for the managers.
