Grahic Jump Location
The system without the gasification unit: GT=gas turbine, SFC=solid fuel combustion (biomass), HR=heat recovery (Yan et al. 8)
Grahic Jump Location
Flow sheet of the EvGT-BAT process integrated with gasification
Grahic Jump Location
Comparison of efficiencies between the reference system with natural gas as additional fuel (NG) and the EvGT-BAT system with an integrated gasification (Syngas) and its modification to improve the heat recovery (HRx)
Grahic Jump Location
Efficiency improvements when drying the biomass feedstock. 1=only the biomass for the gasification process is dried; 2=all biomass is dried; 3=reference system with natural gas and no drying; 4=reference system with natural gas when all biomass is dried.
Grahic Jump Location
Biomass flow rate into the furnace (SFC) and the gasifier and the resulting efficiency versus HTHx operation temperature (TIT constant at 1100°C)
Grahic Jump Location
Comparison between the theoretic dimension of a gasifier in EvGT-BAT at different HTHx temperature with a comparable gasifier in IGCC
