Downdraft Gasifiers - an overview | ScienceDirect Topics
In the downdraft gasifier, as shown in Figure 9.2, the gasification agent (air or O 2) is fed into the middle of the bed (combustion zone) above the stationary grate and the producer gas flows out of the gasifier from the bottom of the gasifier beneath the stationary grate. In this type of gasifier, the fed solid fuel moves downwards together with the gases through a drying zone, a pyrolysis zone, an oxidization (combustion) zone and a reduction zone.
