Özet:

 Nowadays, with the increasing energy demand and concerns about environmental sustainability, hydrogen is regarded as a crucial energy carrier in reducing dependence on conventional fuels. Hydrogen plays a critical role in various fields, particularly in fuel cells. Therefore, due to the undesirable effects of pure hydrogen usage on temperature and emissions, as well as the challenges and high costs of storage, efforts are being made to blend it with conventional fuels in varying proportions to achieve optimal combustion conditions. The aim of this study is to investigate the effects of adding hydrogen gas at different concentrations, without pre-mixing, to the methane combustion reaction inside the burner on flame characteristics. The combustion reaction of CH4 was carried out with six different H₂ concentrations 0, 5, 10, 15, 20, 25, and it was observed that as the H2 ratio increased, the flame temperature rose and its shape became more stable. The maximum flame temperature was recorded as 2732.248 K with 15 H₂. At 25 H2, the mixture exhibited behavior similar to that of a rich combustion mixture. The burner used in this study provides an alternative solution in the field of hydrogen burners.

 Günümüzde artan enerji talebi ve çevresel sürdürülebilirlik kaygıları ile birlikte konvansiyonel yakıtlara bağımlılığı azaltma sürecinde hidrojen önemli bir enerji taşıyıcısı olarak görülmektedir. Hidrojen, yakıt hücreleri başta olmak üzere birçok farklı alanda kritik bir görev üstlenmektedir. Bu sebeple saf hidrojen kullanımının sıcaklık ve emisyon değerleri üzerindeki istenmeyen sonuçları ve depolamasının zor ve maliyetli olması sebebiyle konvansiyonel yakıtlara farklı oranlarda karıştırılarak optimum yanma koşulları oluşturulmaya çalışılmaktadır. Bu çalışmanın amacı brülör içerisindeki metan gazı yanma reaksiyonuna, önceden karıştırılmadan ve farklı konsantrasyonlarda hidrojen gazı eklenmesiyle oluşacak alev spesifikasyonları üzerindeki etkisinin incelenmesidir. Altı farklı H2 konsantrasyonunun 0, 5, 10, 15, 20, 25 CH4 gazı yanma reaksiyonu gerçekleştirilmiş, H2 oranının artmasıyla alev sıcaklığının yükseldiği ve şeklinin daha stabil bir hale geldiği gözlemlenmiştir. Maksimum alev sıcaklığı 15 H2 kullanılarak 2732,248 K olarak elde edilmiştir. 25 H2 kullanımında karışımın zengin karışım gibi reaksiyon verdiği gözlemlenmiştir. Çalışmada kullanılan bu brülör geliştirilen hidrojen brülörleri alanına farklı bir çözüm sunmaktadır.
