Abstract: In the present work, a fixed bed gasifier is modelled using a commercially available software called 'cycle-tempo'. The gasifier performance is studied for varying steam to fuel ratio (SFR), equivalence ratio (ER), gasification operating temperature, moisture content of feedstock. The addition of steam as a gasifying agent along with air improves the H₂/CO ratio, thus aiding in the hydrogen enrichment of syngas. Considering the combined effects of ER and SFR, the H₂ constituent in syngas rises at lower ER and higher SFR values. The heating value of syngas tends to rise for lower ER and SFR values.

Keywords: gasification; syngas; steam to fuel ratio; SFR; equivalence ratio; cold gas efficiency.
