    Investigating impacts of ammonium phosphate on ash yield from co-combustion of sugarcane bagasse and banana leaves
    (LAUTECH Journal of Engineering and Technology 18 (2) 2024: 11-24, 2024-06-04) Oladosu, K.O.; Olawore, A.S.; Ponle, E.A.; Adeniran, I.A.
    High ash yield from the co-combustion of sugarcane bagasse (SGB) and banana leaves (BL) presents significant challenges for efficient biomass combustion in a grate furnace. This study aimed to explore the potential of ammonium phosphate (NH4H2PO4) as an additive to reduce ash yield during the co-combustion of SGB and BL in a muffle furnace. An I-Optimal design of the Combined Methodology (OCD), embedded in Design Expert (version 13.0.5), was employed to design experiments for optimizing ash yield, considering various particle sizes, additive concentrations, and temperatures. The NH4H2PO4 additive was most effective at concentrations between 4% and 7%, beyond which ash yields increased significantly. The optimal composition was determined to be 75% SGB, 20% BL, and 5% NH4H2PO4 at 950°C, resulting in the lowest ash yield of 6.46% and HHV of 22.4MJ/kg. The presence of NH4H2PO4 in the biomass mixture significantly reduced ash yield. The input and output relationship of the biomass additive mixture was modeled using OCD, resulting in R² and adjusted R² values of 0.9825 and 0.9099, respectively, indicating accurate determination of the model coefficients. This study demonstrates that ammonium phosphate additive has great potential in mitigating ash-related problems in biomass combustion.
