- •
The EDC-SGS reaction model is proposed for biomass gasification in BFB.
- •
The simulations with present model are in better agreement with experimental data.
- •
The SGS reaction rates with concentration and temperature are analyzed.
- •
The SGS homogeneous reaction rates account for 15% of total.
- •
The heterogeneous reaction rates with present model are improved 10–15%.
