Use a compatible pot skirt on a biomass stove

Why this can help
A compatible pot skirt can improve heat transfer from a biomass stove to the pot, reducing fuel needed for the same cooking task. Stove experiments support this mechanism.
One possible next step
Ask a qualified local stove programme or supplier whether a tested skirt is available for your stove and pot.
What changes the outcome
Design, clearance and draft are critical. Use a tested compatible system; an improvised metal enclosure can worsen combustion or safety. Better heat transfer does not make biomass smoke harmless.
Your illustrative scenario
Over one year · with the assumptions below
You
20 kg of wood used less
You + 10 friends
220 kg of wood used less
1,000 participants
20,000 kg of wood used less
These are scenarios, not measured personal or collective savings. One separate household per participant. People sharing a home count it once, not once each.
Your inputs
- Wood for the same complete cooking task Before
- 1 kg wood
- Wood for the same complete cooking task After
- 0.8 kg wood
- Comparable occasions per year
- 100
Calculation of the difference: (1 − 0.8) × 100 = 20 kg of wood used
Calculation boundaries
Count only the specified material. This is not a life-cycle assessment and does not convert material into carbon, water quality or biodiversity benefits. Weigh the same wood at comparable moisture, for the same meal and cooking result. This does not measure smoke exposure. Design, clearance and draft are critical. Use a tested compatible system; an improvised metal enclosure can worsen combustion or safety. Better heat transfer does not make biomass smoke harmless.
The initial values are editable arithmetic examples, not measurements or typical savings from the cited studies. Replace them with comparable readings for your situation. The sources support the mechanism and its conditions; they do not predict these numbers.
