[Gasification] GASIFIER MADE FROM CLAY IN BRAZIL

[Paul S. Anderson]

Benjamin and all,

VERY interesting.

What I think I see on the video:

1.  This is an updraft gasifier.  Looks like a hairdryer is the blower for the
primary air.  There is a small water tank probably providing a mist of 
H2O into
the bottom of the hot char bed, causing the water-gas reaction on the red-hot
char with much H2 and CO production.

2.  Gases exit from the top of the gasifier and enter the top of what is
probably some filter and/or cooler and/or cyclone.  Probably exit near the
bottom into a third but shortest "clay hump" furthest to the left in 
the video,
coming upward to a horizontal pipe.

3.  The horizontal pipe has several by-pass valves, but eventually goes to a
Chevrolet 261 engine that is driving a generator or reversed motor to produce
the electric current that is sent to an electrified fence.  The reading on the
meter (is that amps?) is not clearly visible.

4.  Fuel is not discussed, but the ignition is of charcoal in the bottom.  If
this is fueled ONLY by charcoal, the gases could be clean enough for the
engine.  But if fueled by raw biomass, I seriously wonder if they can get the
gases clean enough for long-term running and/or shut-down with cool off and
then restart.

Benjamin, how much more info can you get for us?  Fuel.  Operation time.  What
it looks like when reopened.   How it is refueled.   Diagrams or photos 
of what
is inside the three clay humps.  Who made it and where?  etc.

As I said, VERY interesting.

Paul
