Gasification Tests of Pelletized Biomass in a Downdraft Gasifier

M. Simone, F. Barontini, C. Nicolella & L. Tognotti
Downdraft gasifiers are recognized as the most suitable gasification technology on a small scale due to the very low tar content of the syngas and the high fuel conversion. However some technological issues limit the reliability and diffusion of this technology, in particular tight feedstock specifications such as low moisture content and narrow size distribution. These specifications are hardly met by biomass residues from agriculture and agro­industries, which therefore need to be conditioned before being...
