Abstract

The purpose of this work was to study the effect of blend ratio on thermal behavior and ash compositions of coal/bark co-combustion. The study consistsof two experiments, thermal behavior analysis and ash composition analysis by using the non-isothermal thermogravimetric method (TGA) under combustion conditions and X-ray fluorescence (XRF) respectively. The results of the two experiments can show the interaction between coal and bark at three of blending ratio30:70, 25:75, and 20:80 by weight. Bark shows a good interaction with coal leading to significant reduction in ignition temperature of coal and this effect was more pronounced with higher blending ratio of bark. In addition, it was found that the ash compositions were depended on the blend ratios.
