Background<br />

<strong>Biomass</strong> resources are widely dispersed,<br />

so it costs a lot to collect a large amount <strong>of</strong> biomass<br />

Small-scale gasification system is desirable for on-site use.<br />

Downdraft gasifiers<br />

are <strong>of</strong>ten used for small-scale in Europe.<br />

<strong>and</strong> cannot treat unutiized biomass (bark, bamboo, grass).<br />
