Thanks Mr. Jeff
Yeah! availability is issue. Some of the Gasifier Designer do not recommend
rice husk only because of silica..Just I heard this.
But I need to know how loose biomass can be gasified without briquetting.
What are the technologies? Also How gasification with rice husk is different
from wood fuel?
