Kaya Gazlarının Yanma Karakteristikleri ve İs oluşumu

Bu çalışmada, fakir karışım koşullarında bir yanma odasında metan ve farklı bileşenlere sahip çeşitli kaya gazlarının difüzyon alevleri ve kurum oluşumları incelenmiştir. Kurum modelinin yayınlanmış deneysel verilerle doğrulanmasından sonra, kaya gazlarının alev uzunlukları ve çapları, ara ürünleri, sıcaklıklar ve kirleticiler dikkate alınarak alev karakteristikleri karşılaştırılmıştır. Bu çalışmanın bulgularına göre, Moss-Brookes kurum modelinin One-Step ve Method of Moments modellerine göre daha doğru tahminlerde bulunduğu görülmektedir. Dahası Barnett kaya gazı yanma sırasında en yüksek miktarda kurum yaymaktayken, kaya gazları kadar ara ürün yaymasına rağmen metan gazı en az kurum yaymaktadır. Çünkü kaya gazlarının yanması sırasında daha fazla yanmamış C elementi açığa çıkmaktadır. Bu nedenle, hidrokarbon yakıtlarda C/H oranı arttığında, alevden yayılan kurum miktarı da artar.

Combustion Characteristics and Soot Formation of Shale Gases

In this study, non-premixed combustion characteristics and soot formation of methane and various shale gaseous have been investigated in a combustion chamber under lean combustion conditions. After validation of the soot model with published experimental data, the flame characteristics considering flame lengths and diameters, intermediate species, temperatures, and pollutants of shale gaseous have been compared. The findings of this study show that the Moss-Brookes soot model predicts more accurate than the One-Step and Method of Moments models. Furthermore, the highest amount of soot is released during the combustion of Barnett shale gas. It is minimal for methane despite emitting intermediate species as much as shale gases. Since more unburned C element released during the combustion of shale gases. Therefore, when the C/H ratio in hydrocarbon fuels increases, the amount of soot emitted from the flame also increases.
