Gasification of Solid Recovered Fuel in a Fluidized Bed Gasifier
Short Introductive summary
All experiments were carried out in a 30 kWth small-scale biomass fluidized bed gasification system with air equivalence ratios (ER) of 0.2, 0.3, and 0.4 at 700, 800, and 900 deg-C, respectively. The solid recovered fuel (SRF) pellets mixed with wood pellets were employed as the feedstock. Calcium carbonate (CaCO3) was added to the gasifier to remove chloride. The effects of operational conditions on the syngas composition, tar content, lower heating value (LHV) of syngas, and cold gas efficiency (CGE) were investigated to provide the information as a reference for system commercialization in the future. The preliminary results show that CO and H2 contents increase with increasing the gasification temperature, but CO2 and CH4 show the contrary results. In addition, the amount of syngas, tar production, LHV of syngas, CEG, nitrogen oxides, sulfur oxides, and hydrogen chloride (HCl) contents all decreased with adding CaCO3. The hydrogen chloride content was lower than the detection limit when the Ca/Cl equivalence ratio was 10. Nevertheless, the HCl content in the bottom ash increased after adding CaCO3.
