Abstract

In this study combustion behaviors of 13 mm diameter pellets prepared from blends of lignite and beech wood powders in specific proportions were investigated in air which was flowing upwards by natural convection through a vertical pre-heated furnace system. The results revealed that ignition times of the blends approached to those of wood with temperature and showed certain interactions of the two fuels during volatiles combustion period. Due to these interactions, volatiles combustion times did not comply with combustion rates. However, carbon combustion times of the two fuels and their blends generally complied with rates. It was observed that the change in volatile matter and carbon combustion rate depended on the furnace starting temperature and the fuel ratios in the mixture.

Özet

Bu çalışmada, linyit ve belirli oranlarda kayın ağacı odunu tozu karışımlarından hazırlanan 13 mm çaplı peletlerin ön ısıtmalı dikey bir fırın sisteminde doğal konveksiyonla yukarı yükselen hava içindeki yanma davranışları incelenmiştir. Karışımların tutuşma sürelerinin sıcaklık arttıkça kayın ağacının tutuşma süresine yaklaştığı ve uçucu madde yanma süresi boyunca iki yakıtın belirli ölçüde etkileştiği görülmüştür. Yakıtlar arasındaki bu etkileşimden dolayı uçucu madde yanma sürelerinin yanma hızları ile uyumlu olmadığı, ancak iki yakıtın ve karışımlarının karbon yanma sürelerinin genellikle yanma hızları ile uyumlu olduğu gözlendi. Uçucu madde ve karbon yanma hızındaki değişimin fırın başlangıç sıcaklığı ve karışım içerisindeki yakıt oranlarına bağlı olduğu görüldü.
