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, Mg, and Na elements in the slag block. By investigating the anti-slagging mechanism pathways of the additives in TS biomass pellet fuels, altering of the structure of silicate ion group pathway was found to improve anti-slagging effects that met the requirements of production formula.
