This document discusses a project to introduce pyrolysis cook stoves in Haiti. The project aims to address deforestation by providing an alternative cooking fuel source. Pyrolysis stoves use a closed, natural process to cook with biomass in a way that produces biochar soil amendment. The stoves are designed to stop deforestation, promote local business, protect health, and improve nutrition. They use waste biomass made into fuel briquettes. The stoves have been accepted by beneficiaries due to their practical design, local production, and demonstrations. Challenges include blackened cookware and limited planning skills, but improvements could include better training.

4. Technology stoves
Pyrolysis, combustion with insufficient oxygen
Air supply control:
- Primary air, PL (λ = 0.2)
flows from below into the fuel
and flows upward to the PZ
- Secondary air, SL (λ = 2.5)
is in the double-wall pre-
heated and flows into the MZ

5. Technology combustible
Waste biomass into fuel
• Fuel briquettes out of rubbish
takes waste into source of
energy
• Materials like agricultural
residue (try leaves, grasses
etc.) from banana, sugar cane,
riz husk, straws, sawdust…
• 20 to 30% mixed up with
waste paper and cardboard

8. Succeses and difficulties
technology acceptance
+ Meets their cooking habits
+ model for a self made press
+ own experience of fuel composition
+ Embed results from user studies
- cookware will be black
- press only for small quantities
- paper is not always present
- reloading of burning material disturbing
- planning skills are missing
