Optimum Conditions for Gasification in Dual Fixed Bed Gasifier

Abstract

Optimum conditions for gasification of wood chips were experimentally investigated in dual, small-sized fixed bed gasifier (153mm φ × 420mmH) with air. The experiments have been performed using two different sizes of wood chips (41 × 14 × 5mm ; 13 × 8 × 3mm).
As a result, the gasification temperature of 1173-1273K in the gasifier may be optimal to gasify the wood chips. The gaseous product from the large-sized wood chips can be used as a gaseous fuel (higher heating value, 5990kJ/Nm³) for internal combustion engines.
