  1. What is an Improved Stove? Dean Still Aprovecho Research Center

  2. Testing Stoves • The Water Boiling Test is a standardized method of comparing cook stove performance, involving: • Cold start to boil • Hot start to boil • Simmer for 45 minutes • Performed under emissions collection hood for real-time measurement of CO, CO2, and PM

  3. Three Stone Fire

  4. Ghana Wood Stove

  5. VITA

  6. Rocket Stove

  7. Average Fan Stove

  8. Stoves and Fuel Use

  9. Stoves and CO Emissions

  10. Stoves and PM Emissions

  11. Increasing Heat Transfer Efficiency • Using a Haybox

  12. Increasing Heat Transfer Efficiency • Reducing Evaporation and Simmering with Leftover Charcoal

  13. Increasing Heat Transfer Efficiency • Cooking Larger Quantities *Institutional Stove performance measured as consumption and emissions per Liter multiplied by 5 Liters for comparative purposes

  14. HTE or CE? • What is more important for fuel savings and lowering emissions? • Heat Transfer Efficiency or • Combustion Efficiency or • Both?
