Comparison of Inert and Oxidative Torrefaction Process Applied to Vineyard Pruning Waste

Öz

In the present study, the change in the product yield and fuel properties of the vineyard pruning waste (BBA) was investigated with the torrefaction process applied in different environments in order to improve the fuel properties of agricultural wastes. BBA was first torrified at 280ºC, in inert and oxidizing environments, for a short residence time. In order to determine the change in the fuel properties of the biochar formed as a result of the process, the change in the upper heat value and energy efficiency was determined together with the proximate and elemental analyzes. Torrefied and raw biomass were burned in a fixed bed with natural convection and differences in combustion behavior were evaluated and compared.. The results of study show that the fuel properties of the biochar formed after torrefaction in both environments improved. As a result, it can be said that oxidative atmospheres can also be used for torrefaction at high processing temperatures.

Bağ Budama Atığına Uygulanan İnert ve Oksidatif Torrefaksiyon İşleminin Karşılaştırılması

Öz

Sunulan çalışmada tarımsal atıkların yakıt özelliklerinin iyileştirilmesi amacıyla farklı ortamlarda torrefaksiyon işlemi uygulanan bağ budama atığının (BBA) biyokömür (katı ürün) verimi ve yakıt özelliklerindeki değişim araştırılmıştır. Bunun için BBA önce 280ºC’de, inert ve oksitleyici ortamlarda, kısa kalma süresinde torrefiye edilmiştir. İşlem sonucu oluşan biyokömürün yakıt özelliklerindeki değişimin tespiti için kısa ve elementel analizler ile birlikte üst ısı değeri ve enerji verimindeki değişim belirlenmiştir. Ayrıca elde edilen biyokömürün doğal konveksiyonlu sabit yatak yakma sisteminde yanma davranışı incelenerek ham biyokütle ile karşılaştırılmıştır. Yapılan çalışma sonucunda her iki ortamda da torrefaksiyon sonrası oluşan biyokömürün yakıt özelliklerinin iyileştiği tespit edilmiştir. Sonuç olarak yüksek işlem sıcaklıklarında torrefaksiyon için oksidatif atmosferlerin de kullanılabileceği sonucuna ulaşılmıştır.
