This study investigates the thermal and kinetic analysis of six diverse biomass fuels, in order to provide valuable information for power and energy generation. Pyrolytic, combustion and kinetic analyses of barley straw, miscanthus, waste wood, wheat straw, short rotation coppicing (SRC) willow and wood pellet were examined by non-isothermal thermogravimetry analyser (TGA), differential thermogravimetric (DTG) and differential scanning calorimetry (DSC) techniques. Biomass fuels were thermally degraded under N₂, air, CO₂ and the selected oxy-fuel (30% O₂/70% CO₂) reaction environments. The thermal degradation under inert N₂ and CO₂ atmospheres showed an almost identical rate of weight loss (R), reactivity (R_M × 10³) and activation energy (E_a) profiles. Similar profiles for R, R_M and E_a were observed for the environments under air (21% O₂/79% N₂) and the oxy-fuel combustion. Results indicated …
