f Co-Combustion Performance of Oil Shale and Biomass Fuels

Co-combustion performance of two oil shales and four biomass types were investigated. Differential scanning calorimeter and thermogravimetric analyser were used to analyze the samples. The oil shale samples are from Ulukışla and Himmetoğlu regions in Turkey. The biomass samples used in the study are hazelnut shell, wheat bran, poplar, and miscanthus. The aim of this study was to evaluate the co-combustion performance of oil shale and biomass at different biomass proportions (10, 20, and 50 wt.%) in blends at three different heating rates (10, 30, 50 oC/min). The ignition temperatures of the parent fuels and blended fuels were investigated to identify any improvement in combustion performance with the addition of biomass. All results were investigated statistically to identify possible relationships between ignition temperatures and physical properties of the fuels.
