The behaviour of ash of fuel afects its thermal efciency when in use. The ash analyses of bio-coal briquettes developed from lean grade coal and torrefed woody biomass have received limited intensive study. Therefore, the present study aims at analysing the ashes of briquette made from lean grade coal and torrefed woody biomass using blended coal tar pitch and molasses as the binder. Bio-coal briquettes were produced from coal and torrefed biomass in various hybrid ratios. Ashing of various briquettes was done in a mufe furnace at 850 °C for 3 h. Mineral phases of the ash were identifed using an X-ray Difractometer (XRD), while the mineral oxides were obtained using an X-ray Fluorescence Spectrometer. The AFT700 Furnace was used with its AFT700 software to evaluate the ash fusion temperatures of the ashes. The XRD patterns look similar, and quartz was found to be the dominant mineral phase present in the raw coal and bio-coal briquettes. The SiO2 (57–58%), Al2O3 (19–21%), and Fe2O3 (8–9%) were the major oxides observed in the ashes. The fnal fusion temperatures of the ashes range from 1300–1350 °C. The compositions of the ashes of the bio-coal briquettes are classifed as detrital minerals. It was concluded that the addition of torrefed biomass (≤10%)and blended binder (≤ 15%) to coal gave a negligible impact on the ashes of the resultant biocoal briquettes.
