UPDRAFT GASIFIER SYSTEM

In Updraft Gasifier System, air (oxygen) supply is fed into the chamber at the bottom, and this air flow acts as counter-current to the movement of biomass material. After going through the process, the producer (inflammable) fuel gas rises upward and is finally collected and drawn off at the upper part of this Gasifier. It contains clearly allocated zones for the partial combustion, reduction and pyrolysis process of the biomass. Updraft Gasifier achieves higher efficiency as the hot air passes through biomass material bed and leaves the Gasifier at lower temperature. The heat given off during the process of gasification is used for preheating and drying the fed biomass.

Updraft Gasifier is best suited for the applications where moderate amount of dust in the fuel gas is acceptable and a higher flame temperature is required.
