Abstract

There are two main forces for the search for alternative technologies to mono/co-combustion of sewage sludges and wastes. These are the large quantity of flue gas and ash formed during combustion. After combustion, up to 50 wt % of the input dry mass of sludge remains as ash and most of the toxic heavy metals in sludge are retained, this complicates ash disposal. To reduce the quantity of ash for disposal, there are several new technologies which are combinations of the three process, i.e. pyrolysis, combustion and gasifications. This paper summarizes the new alternative technologies and applications.

Özet

Katı atık ve arıtma çamurlarının tek başına veya diğer yakıtlarla birlikte yakılmasına alternatif teknolojiler araştırmak için iki önemli sebep bulunmaktadır. Bunlar, yanma boyunca oluşan büyük oranlardaki baca gazı emisyonları ve küldür. Yanma sonrası başlangıç kuru kütlenin yaklaşık %50'si kül olarak kalmakta ve bir çok toksik ağır metalleri içermektedir. Böylece külün uzaklaştırılması karmaşık hale gelmektedir. Bu kül miktarını azaltmak için piroliz, yakma ve gazlaştırma işlemlerinin kombinasyonu şeklinde bir çok yeni teknoloji geliştirilmiştir. Bu makalede yeni teknolojiler ve uygulamaları özetlenmektedir.
