Son yıllarda, kömür madenciliği teknolojisi büyük ölçüde mekanize edilmiş, bu da üretilen kömürde önemli oranda ince kömür içeriğine neden olmuştur. İnce kömürlerde temizlenmeden doğrudan kullanıldığında ciddi hava kirliliğine ve katı atıklara yol açarak çevre için büyük bir risk oluşturabilir. Bu nedenle, ince kömürün kullanılmadan önce temizlenmesi çok önemlidir. Yağ aglomerasyonu, ince boyutlu kömürlerin temizlenmesinde kullanılan yöntemlerden biridir. Ancak, bu yöntemde kullanılan yağ miktarının fazla olması nedeniyle yöntem genellikle ekonomik olarak uygun görülmemektedir. Bu sorunu çözmemin yolu, yöntemde bağlayıcı olarak kullanılacak yağın sisteme emülsifiye edilerek verilmesi veya bağlayıcı olarak atık yağların kullanılması olabilir. Yağların sisteme emülsifiye edilerek verilmesi yöntemde kullanılan yağ miktarını azaltabilir. Böylelikle yöntemin en büyük dezavantajı olan yağ maliyeti azaltılabilir. Son yıllarda yağların emülsifikasyonunda ultrasonik dalgalar kullanılmaya başlanmıştır. Bu çalışmada, çok ince boyutlu yüksek kül-kükürt içerikli kömür bitkisel atık yağ ile aglomerasyon işlemine tabi tutulmuştur. Atık yağ emülsifiye edilerek ve emülsifiye edilmeden aglomerasyon deneyleri yapılmış olup elde edilen sonuçlar karşılaştırılmıştır. Ultrasonik cihazla emülsifiye edilen atık yağ (%10 yağ miktarı) ile aglomerasyon deneyi yapıldığında en yüksek yanabilir verim değeri %93,46 olarak elde edilmiştir. Atık yağ emülsifiye edilmeden yapılan aglomerasyon deneyinde ise yanabilir verim değeri %82,87 olarak bulunmuştur. Kül giderimi değerleri ise %39,17-46,92 arasında değişmiştir.

Effect of Ultrasonic Emulsification on Oil Agglomeration of Coal

In recent years, coal mining technology has been largely mechanized, resulting in significant fine coal content in the coal produced. Direct use of fine coals without cleaning can lead to serious air pollution and solid waste, posing a major risk to the environment. Therefore, it is very important to clean fine coal before use. Oil agglomeration is one of the methods used to clean fine coal. However, due to the high amount of oil used in this method, the method is generally not economically viable. The way to solve this problem is to emulsify the oil to be used as a binder in the method or to use waste oil as a binder. Emulsifying the oils into the system can reduce the amount of oil used in the method. Thus, the oil cost, which is the biggest disadvantage of the method, can be reduced. In recent years, ultrasonic waves have been used in the emulsification of oils. In this study, very fine sized coal with high ash-sulfur content was subjected to agglomeration process with vegetable waste oil. Agglomeration experiments were carried out with and without emulsifying waste oil and the results obtained were compared. When the agglomeration experiment was performed with waste oil emulsified with ultrasonic device (10% oil content), the highest combustible recovery value was 93.46%. In the agglomeration experiment without emulsifying the waste oil, the combustible recovery value was 82.87%. Ash rejection values ranged between 39.17-46.92%.
