Combustion of raw and densified Tunisian oleic by-products in a fixed bed reactor

摘要: Abstract Combustion of biofuels prepared by blending or not olive mill solid residues (olive pomace and pits) with pine sawdust (S) wood chips (WC) was investigated. The mass loss, the bed temperature front reaction position were determined. characteristic numbers such as heating release (HR) ignition rate (IR), conversion (MCR) excess air coefficient (λ) also Gaseous emissions main species (O2, CO2, CO, H2O, Corganic analyzed measured in freeboard zone reactor. Moreover, NOx (N2O + NO) SO2 emission profiles drawn post-combustion chamber. All results mainly compared to our previous works that dealt other blends pellets wastes, but tested researchers similar conditions. Main exhibit a substantial decrease ash content when sawdust. Temperature show an increase from ambient value maximum ranging between 800 1075 °C accordance what is usually found literature using biomass biofuels. In all samples, concentrations pollutants notably reduced be acceptable regarding European standards. Furthermore, combustion made 50%–50% mixture pits leads more efficient homogenous combustion.
