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.
