Abstract

Bu çalışmada, farklı CH4/ C3H8 / CO2 /N2 içeriklerine sahip kaya gazı karışımlarının yanma ve emisyon davranışları deneysel olarak incelenmiştir. 4 kW ısıl güç ve 0,7 eşdeğerlik oranı ile dört farklı girdap değeri (0.2/0.6/1.0/1,4) kullanılarak emisyon ölçümleri incelenmiştir. Tüm kaya gazları için sonuçlar metana göre yorumlanmıştır. Test edilmiş kaya gazı karışımları; K1 %85 CH4- %0 C2H6- %5 C3H8- %0 CO2-%10 N2, K2 %85 CH4-%0 C2H6-%10 C3H8-%0 CO2- %5N2, K3 %85 CH4- %0 C2H6- %5 C3H8- %5 CO2-%5 N2, K4 %85 CH4 - %0 C2H6 - %10 C3H8 - %5 CO2-%0 N2, K5 %85 CH4 - %0 C2H6 - %5 C3H8 - %10 CO2-%0 N2, K6 %80 CH4 - %0 C2H6 - %10 C3H8 - %5 CO2 -%5 N2. Bu çalışma sonucunda kaya gazlarının içeriğine bağlı olarak emisyon değerlerinin büyük farklılıklar gösterdiği görülmüştür. Tüm kaya gazlarının metandan daha fazla NOx ve CO değeri oluşturduğu gözlemlendi. Kaya gazı karışımındaki C3H8 değeri NOx değerinde ve baca gazı sıcaklığında artışa neden olurken, CO2 oranındaki artışla CO değeri artarken NO ve baca gazı sıcaklık değerleri azalmıştır.
