Various Effects of Diluents Used in Combustion Experiments on Combustion

Öz

Climate change causes the ozone layer to deplete, the seasons to change and the earth's temperature to increase. Today, rising temperatures, melting of glaciers and temperatures above seasonal normals show the negative effects of global warming on our lives even more clearly. In this context, the search for alternative fuels and combustion methods has gained momentum. Fossil fuels still meet a large part of our energy needs. Although studies for renewable and sustainable energy are gaining momentum, solutions are sought that will both reduce harmful emission values from fossil fuels and maximize efficiency with energy output. Dilution is not only used in combustion reactions. It contributes to studies in the field of methods used in areas such as chemistry and food industry. In this study, the effect of dilution method on combustion performance was investigated within the scope of the literature study. The diluents selected as samples were determined as N2, CO2, Ar and H2O and various effects of dilution results on the reaction are seen in the studies of the determined diluents. In the studies, factors such as the effect of dilution on laminar combustion rate, flame temperature, optimum ranges of equivalence ratios for dilution and change in emission values as a result of dilution were discussed.

Yanma Deneylerinde Kullanılan Seyrelticilerin Yanma Üzerindeki Çeşitli Etkileri

Öz

İklim değişikliği ozon tabakasının incelmesine, mevsimlerin değişmesine ve dünyanın ısısının artmasına neden olmaktadır. Günümüzde yükselen sıcaklıklar ile buzulların erimesi ve mevsim normallerinin üstünde seyreden sıcaklıklar küresel ısınmanın hayatımıza olan olumsuz etkilerini daha da net olarak göstermektedir. Bu bağlamda alternatif yakıt ve yanma yöntemleri arayışı hız kazanmıştır. Fosil yakıtlar halen enerji ihtiyacımızın büyük bir bölümünü karşılamaktadır. Yenilenebilir ve sürdürülebilir enerji için çalışmalar hız kazansa da fosil yakıtlardan hem zararlı emisyon değerleri düşük olacak hem de enerji çıkışıyla verimi en yüksek seviyeye çıkaracak çözümler aranmaktadır. Seyreltme sadece yanma tepkimelerinde kullanılmamaktadır. Kimya, Gıda endüstrisi gibi alanlarda da kullanılan yöntem alanlarındaki çalışmalara katkı sağlamaktadır. Bu çalışmada seyreltme yönteminin yanma performansı üzerindeki etkisi literatür çalışması kapsamında araştırılmıştır. Örneklem olarak seçilen seyrelticiler ise N2, CO2, Ar ve H2O olarak belirlenmiştir ve belirlenen seyrelticilere ait çalışmalarda seyreltme sonuçlarının tepkimeye olan çeşitli etkileri görülmektedir. Yapılan çalışmalarda seyreltmenin laminer yanma hızına, alev sıcaklığına olan etkisi, eşdeğerlik oranlarının seyreltme için optimum aralıkları ve seyreltme sonucu emisyon değerlerindeki değişim gibi etmenler ele alınmıştır.
