[Gasification] Adobe Updraft Charcoal Gasifier

[andy schofield]

Dear Dr. Anderson,    I Agree, This system is very interesting. Senior Benjamin Boff has since contacted Senior Danillo the builder, and encouraged him to post a description on a yahoo group. Senior Danillo shows a cut-away elevation of the reactor. It is a bottom-lighted updraft (BLUD), fueled with charcoal. 
 
   My friend Mike LaRosa in Wisconsin, suggested he drip water into the hot char-bed. Senior Danillo later replied that it made a big improvement in engine power! Senior Danillo noted it is in mid-run that the H2 effect is the highest.
 
   Senior Danillo has plans to construct an adobe Imbert-type for raw wood. This is a technically challenging project, and would be a great advance to the art. However, harvest time is approaching, and Senior Danillo has his skilled masons improving the coffee-drying facilities.
 
So far as I  have learned, these are the answers to the questions you have asked: 1. Note the two green hoses connected to the water-jacketed air-blast pipe. This is thermo-siphon cooling so the nozzle won't burn up. 2. These are a series of chambers to cool the gas, and  remove dust. They largely remain a mystery to me. No specific details as yet.  3. The instrument measures Ampere, Paul. I read ~30A. If the three wires you saw, were phases from the alternator, it would be a convenient way to harvest, and cook tasty and nutritious wild animals, however this is not the case. It would not be safe!  Senior Danillo uses flexible power-cable to connect to his modern farm circuit. 4. Senior Danillo only uses  clean charcoal in this system.
 
   I can't wait to see what he builds next!
