Abstract

Coals react with oxygen from the moment they are produced and are subject to spontaneous combustion. As a result of the reaction, they emit harmful and dangerous gases to their surroundings. In addition, this situation leads to a reduction in the calories of coals. In the same way, losses of calories occur in the calories of coals under the rays of the sun due to their being exposed to the sun's ultraviolet rays to human influence. In this study, the changes that occur in both imported and domestic coals sold for commercial purposes in Konya by applying different milling times and different durations in calories changes under the influence of microwave in calories, are examined.

KONYA BÖLGESİNDE SATILAN KÖMÜRLERDE ÖĞÜTMENİN KALORİ KAYBINA ETKİLERİNİN ARAŞTIRILMASI

Abstract

Kömürler üretildikleri andan başlayarak oksijenle reaksiyona girer ve kendiliğinden yanmaya maruz kalırlar. Reaksiyon sonucunda bulundukları ortama zararlı ve tehlikeli gazlar yayarlar. Ayrıca bu durum kömürlerin kalorilerinde bir azalmaya sebep olur. Aynı şekilde güneş ışığı altında kalan kömürlerin kalorilerinde, güneşin ultraviyole ışınlarının etkisinde kalmasıyla, kayıplar meydana gelmektedir. Bu çalışmada, Konya ilinde ticari amaçlı satılan ithal ve yerli kömürlerin farklı öğütme süreleri uygulanarak kalorilerindeki değişimler ve farklı sürelerdeki mikrodalga etkisinde kalorilerindeki meydana gelen değişimler incelenmiştir

Keywords
