Abstract Since pure tobacco stalk (TS) biomass pellet fuels tend to slag, five anti-slagging agents were added to the crushed TS to obtain a pellet fuel that could be used in biomass burners to provide heat for tobacco curing. The obtained results revealed that the main component of TS pellet fuel was K₂Si₂O₅. During fuel combustion process, additives generated higher melting point silicate compounds by Al–K, Ca–K, and Ca–K elemental structures to replace single K elemental structure of TS, enhancing the anti-slagging efficiency of the pellet fuel from 21.63% to 78.29% and promoting the precipitation of K, More >

Abstract The presence of toxic elements in manganese slag (MSG) poses a threat to the environment due to potential pollution. Utilizing CO curing on MS offers a promising approach to immobilize toxic substances within this material, thereby mitigating their release into the natural surroundings. This study investigates the impact of CO cured MS on various rheological parameters, including slump flow, plastic viscosity (η), and yield shear stress (τ). Additionally, it assesses flexural and compressive strengths (f and f), drying shrinkage rates (DSR), durability indicators (chloride ion migration coefficient (CMC), carbonization depth (CD)), and the leaching behavior of heavy… More >
