Grasifier

Roger Samson was here tonight and we made and tested a Grasifier: a Switchgrass burning stove based on the dimensions of the Vesto adapted to make a lower cost pellet burning stove for Haiti.

Power, 2.5 kw
Burn rate 8-10 g/min
Mass 550 g
Fuel load 600 g though it can hold 750

Lighted with two caps of paint thinners
The flame went completely blue (just before the end) then wobbled a lot and went out.
When it went out there was no smoke indicating there were no volatiles left.

Time to fabricate, about 30 minutes.

I see this as a burner that can be attached to the centre of a Haitian charcoal stove to convert it into very clean burning a pellet stove.

Char yield: 25% of the initial dry mass.
Moisture content of the initial fuel, about 7%

Ash: nearly none.

Roger Samson, REAP-Canada, April 2006

In the Gambia, wood is used for cooking, construction, and local tool production. There is often more need for wood, than the number of local trees can support.

REAP-Canada developed the Mayon Turbo Stove to help reduce people's dependency on wood as a source of fuel for cooking meals. This stove was developed by REAP in cooperation with the local people of the Gambia, and it burns well with selective crop residues. millet husks, peanut shells, corn cob pieces, small pieces of grass and rice hull. This allows the women of the Gambia to forage for fuel close to home, relieves a burdon on families that would otherwise be paying for fuelwood.
