International Journal of Sustainable Energy, Volume 43, Issue 1, 2024, Article number 23848731478-6451https://doi.org/10.1080/14786451.2024.2384873https://dspace.lib.cranfield.ac.uk/handle/1826/22754The current research investigates the combustion characteristics of bioslurry fuel derived from the products of agricultural waste pyrolysis. The bioslurry fuel was prepared by mixing biochar and pyrolysis oil. The combustion characteristics of a suspended single droplet of the bioslurry were analysed. The results indicate that an increase in pyrolysis temperature (400–600°C) lead to higher concentrations of fixed carbon (56–60%), increased ash content (16–18%), and higher calorific values (25–32 MJkg−1). As the pyrolysis temperature rises, the biochar surface becomes more porous, lower volatile matter content and particle size. As biochar content increases, the bioslurry’s density, viscosity, and caloric value increase but stability index decreases. Higher biochar content in the bioslurry increases the ignition delay and burnout time while reducing the burning rate. The bioslurry fuel contained 30% biochar achieved a calorific value of 28 MJkg−1 and a viscosity of 600 cP, comparative to conventional fossil fuels.enAttribution 4.0 Internationalhttp://creativecommons.org/licenses/by/4.0/Agricultural wastebiocharbioslurrycombustionpyrolysisslurry fuelArticle1478-646X
