Belonio Gasifier: Drawbacks● Loading and unloading is inconvenient● Wind puts flame out easily● Disastrous failure mode if left on● RESULT: 10% adoption rate (Vietnam National University, 200 stove study)
Remote Burner● One possible solution: downdraft operation, burn gas in separate burner ● Allows continuous operation
Remote Burner● BUT ● Lighting now not as easy ● Persnickety burners ● Tar collection in pipes (cooking gasifiers are run largely in the pyrolysis mode, not gasification. 90 SGR* vs. 140 SGR for gasification) *SGR: Specific Gasification Rate [kg / hr-m^2]
Rice husk cook stoves: Manydesigns are technically possible,but no product exists thatbalances technical feasibility withuser needs at a large scale.
