Rocket Stove Primer: Meeting notes via CRASH Space

  1. Insulate, particularly the combustion chamber
  2. Use an insulated, upright chimney above the combustion chamber, of a height 2-3 times the diameter
  3. Heat only the fuel that is burning
  4. Maintain a good air velocity through the fuel.
  5. Do not allow too much or too little air to enter the combustion chamber. Strive to have stoichiometric (chemically ideal) combustion Note: Most hobbyists find designating ⅓-½ of the feed tube for air to be ideal
  6. The cross sectional area of the combustion chamber should be sized within the range of power level of the stove. 25 square inches will suffice for home use.
  7. Elevate the fuel and distribute airflow around the fuel surfaces. When burning sticks of wood, it is best to have several sticks close together, not touching, leaving air spaces between them.
  8. Arrange the fuel so that air largely flows through the glowing coals.
  9. Throughout the stove, any place where hot gasses flow, insulate from the higher mass of the stove body, only exposing pots, etc. to direct heat
  10. Transfer the heat efficiently by making the gaps as narrow as possible without choking the fire.
