Recovery of a Wood Biomass Gasifier for IC Engines: Analysis and Adjustment of Thermo-Chemical Parameters

G. Allesina & P. Tartarini
This work is aimed at investigating possible causes of tar overproduction in a gasification system coupled to two IC­engines producing 250 kW of electric power. The gasifier, a stratified downdraft reactor, is fed with woodchips. In order to reduce the tar production, a measuring campaign and a simple mathematical model of the system have been set up. Experimental data have been acquired by different methods, such as pressure drop analysis for air flow rate measurement...
