Abstract

Isıl işlemle ilgili yapılan çalışmalar daha çok bu malzemenin fiziksel ve mekaniksel özellikleri üzerine yoğunlaşmıştır. Isıl işlem görmüş ağaç malzemenin yanma özellikleri üzerine yeterli çalışma yoktur. Bu çalışma da ısıl işlem görmüş ağaç malzemelerin yanma özellikleri belirlenmiştir. Yanma sonuçlarına göre, ısıl işlem görmüş ağaç malzemenin ağırlık kaybı değerleri, genel olarak kontrol ağaç malzemeden düşüktür. Isıl işlem görmüş ağaç malzemenin üst sıcaklık ve baca sıcaklık değerleri, kontrol ağaç malzemeden yüksektir. Yanma deneyi süresince, ısıl işlem görmüş ağaç malzemenin karbon monoksit (CO), azot monoksit (NO) ve oksijen (O2) kaybı değerleri genel olarak kontrol ağaç malzemeden yüksektir.

Determination of Combustion Properties of Heat Treated Wood Materials

Abstract

Studies on heat-treated wood are mostly focused on physical and mechanical properties. There is no sufficient study on combustion properties of heat-treated wooden material. In this study, combustion properties of heat-treated wooden material were determined. According to results of combustion, mass reduction in heat-treated wooden material less than non-heat-treated wood material. Temperature values of the heat-treated wooden material are higher than control samples. During combustion test, also, it was noticed that the amount of released gases such as carbon monoxide (CO), nitrogen oxide (NO) and oxygen (O2) values in heat-treated wooden material are higher than control ones in general.
