Introduction

Biomass Gasification Using a Fixed-Bed Downdraft Gasifier

The feedstock under study includes wood waste, saw dust, slash, mill sludge, peat and agricultural residues, etc. The approach of this research is to design and construct a bench-scale fixed-bed gasifier with biomass processing capacity of several kilograms per hour and to develop a standard characterization procedure. Then, the effect of the

Fixed Bed Gasifiers - an overview | ScienceDirect Topics

There are three types of fixed bed gasifiers, as shown in Fig. 16.5: updraft (counter-current), downdraft (co-current), and cross draft gasifier. In case of the updraft gasifier, the fuel is supplied at the top and the air at the bottom so that fuel moves against the air flow, while in the case of the downdraft, air is introduced above the oxidation zone and the product gas is removed from the
