Cooking without Smoke – Biomass Gasification

Gasification

Micro Gasification

Gasification is a simple thermo-chemical process that:

  • Maximises the use of the volatile energy stored in biomass fuels
  • Improves the fuel combustion and heat transfer by over 50%
  • Reduces smoke and carbon monoxide fumes by over 90% compared to an open fire
  • And produces bio-char as a by product (20% of the fuel mass burned)

Micro-gasification stoves were first promoted in the late 1980’s. The 2 stage combustion process, first breaks down the biomass components (cellulose, hemi-cellulose and lignin) into combustible gas. The second stage burns the “produced” gas much like a normal gas stove.

FA (Forced Air) Gasification with the use of a fan is far more effective that ND (Natural Draft) Gasification used in some improved cookstoves as the forced air creates more heat with less harmful emissions.

FA Gasifier stoves, when used with densified pellets fuel, produce a consistent and variable gas flame with complete combustion. This increases the efficiency and significantly lowers the harmful emissions normally associated with a wood fire.

The FabStove Gasifier Canister has a load capacity of 700 grams of pellets and uses 600g of fuel per hour at full power which provides 3 kW of heating. Less fuel is consumed at lower power levels .

The heat output is sufficient for most cooking tasks in the home.
