[Gasification] tests to design a new cheap gasifier fan

[Mark Ludlow]

Robert,
This sounds very resourceful! For the hand-cranked blower units, what sort
of speed-up transmission do you envision to spin the blowers fast enough to
get the required suction head? Using a compressed air eductor is horribly
inefficient, as jim realizes. Will you connect to an IC genset after
everything is balanced-out?

  Dear Jim,
Your gasifiers are negative pressure, when I built mine, never used the 
air compressor, just add a small blower ( 2" Chinese made) to air intake 
and started as pressurized until I got clean gas. I also used the bigger 
suction blower (3" also Chinese made cost me $ 50.00 in Indonesia) after 
my scrubber and  filter to start gasifier in suction mode. I tried using 
the same type blower before right after the cyclone and already burned 
one. With the big blower I achieved 4-8" water pressure. My reactor is 
26 cm diam. and the blowers seem to work fine.
Even here in Indonesia it is not worth for me try to built the  blower, 
but we did for the hot gas for another project. We took a regular 
blower, separated the shaft and use different motor and cast ceramics 
around shafts, than we wrapped with insulating glass fiber and steel 
clamps. We could handle gas up to 300 degrees with that unit. For the 
rural areas we are planning to use hand cracked blowers.
