Biomass Gasification and the Benefits of Biochar - Dr Paul Olivier

If you are interested in biomass stoves (TLUD) or the multiple applications for small scale biomass gasification then I highly recommend a review of Dr Paul Olivier's work in Vietnam with rice husk biomass. His 10 page report (link below) includes reports on biochar agriculture trials in Cambodia and Laos using rice hulls. His report also includes an interesting summary of possible future distributed energy pathways for biomass.

This is a TLUD forced air gasifier in operation on rice hulls.

Here you see the burner with burner housing:

When a wire mesh dome is placed on top of the burner and burner housing,  this roughly doubles the amount of heat being transferred to a pot:

Here it took 3 minutes and 42 seconds to bring a liter of water to a boil:
