17. Hybrid Gasification Process
18. HGL Gasifier Key Features Offers uniform airflow through the fuel bed when fuel is allowed to flow under gravity without any constriction.
Hybrid gasification design has accommodated all the features required for a perfect gasification unit to treat difficult residues with variable ash composition.
This makes it suitable for a wide variety of solid biomass feed stocks.
19. Gasifier Zones The gasification process can be divided into three main zones
Fuel feeding zone – Top one third
Fuel gasification zone – Middle one third
Ash discharge zone – Bottom one third
