Hybrid Stove Making Charcoal (YouTube)
Lanny Hensoni, July 26, 2007

Biomass cooking stove burns wood to charcoal and saves the charcoal. One pound of wood cooks 6 kilos of rice and makes 65 grams of char.

Hybrid Stove Burning Bamboo Pan Cooking

See: http://www.youtube.com/watch?v=oIsNZHSkX8k

Here is another 3 min video of the Hybrid Stove burning bamboo chips and pan cooking eggs.
Bamboo chips burns well in the Side Supply Burner but the pan only reached medium heat.
The heat from the burner seems to be diffusing and bypassing the pan. Enough heat is being generated by the burner but the pan module lacks focus.
Suggestions to fix pan module?

Below you will find an interesting discussion, concerning the drying of fuel,
that was on the gasification list.

The Drying Process I use is simple, the sun and an inclined sheet of heavy
wire screen mounted in a large tiltable frame, chips are loaded onto the
screen, screen is inclined, and about 3 hours later, the chips start to
slide, or tumble down (moisture released, they are now lighter in mass, and
slide down),

160 grams of charcoal boils and simmers 5 liters/CF04 Stove
Lanny Hensoni www.lanny.us July 2, 2006

The CF04 Stove boiled and simmered 5 liters using only 160gr of charcoal and wood.

After several modifications to 4 different prototypes, it only took 150 gr of lump charcoal with 11% moisture and 10gr of wood to boil 5 liters of 83 degF/28.3 degC water in 45 min. That is 32 grams per liter to boil and simmer. At 1 hour after boiling the water was still simmering at 100 degC and after 2 hours the water was 205degF/96 degC. At this point I shut the air control and capped the pot module to stop the airflow and retain heat.

At 3 hours the water temp was 190 degF/87.8 degC and was 178 degF/ 81 degC at 4 hours.

In order to make my first batch of fireballs I needed some charcoal fines or dust. I charred some switchgrass and leaves to start with. That would be easy to reduce, but was unsure how to go about this task at hand. Having already removed the paddles from the cement mixer, I got the bright idea to place the switchgrass and leave char in the cement mixer plus one large rock, see picture #1. So I gave it a try, not knowing that there is such a device as a ball mill. I learned fast that a lid was in order! Dust cloud anyone? This worked well for the charred switchgrass.
