<DIV><STRONG><FONT face=Arial size=2>Hi Jim and
colleagues,</FONT></STRONG></DIV>
<DIV><STRONG><FONT face=Arial size=2></FONT></STRONG> </DIV>
<DIV><STRONG><FONT face=Arial size=2>Always good ideas to pick up from these WW2
gasifiers.</FONT></STRONG></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>video of Swedish A. B. Gasgenerator. more things to
learn from the ancients!</FONT></DIV>
<DIV><FONT face=Arial><BR><FONT size=2></FONT></FONT></DIV>
<DIV><FONT face=Arial size=2>i just stumbled across this rebuild project of an
old sweedish<BR>gasifier on youtube.<BR><BR>the done unit is here:<BR></FONT><A

<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><STRONG><FONT face=Arial size=2>Before you get excited about the
simplicity, first identify the type of gasifier you are looking at. This is a
charcoal gasifier with a cloth filter, never used for wood gasifiers, because of
the condensate issues.</FONT></STRONG></DIV>
<DIV><BR><FONT face=Arial size=2>there are many interesting details on these
machines. note the long<BR>curved cooling tubes that conform to the
reactor/hopper. they nicely<BR>junction into a box on each end where they
can have the pipe cleaner<BR>poker passed through. designed for service,
as they should be!</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2><STRONG>Horizontal pipes only work with a charcoal
gasifier, because the gas is dry and rarely needed cleaning.</STRONG></DIV>
<DIV><BR>the second video shows the inards of the filter. i'd never seen
this<BR>type of hoop and cloth filter. very interesting. still, i
think if<BR>they had our reticulated foams in all ppi back then, they'd likely
be<BR>using such. then again, we still build k&n filters out of
gauze<BR>(though not to great filtering success).</DIV>
<DIV> </DIV>
<DIV><STRONG>Page 174-5 of Gegas The Swedish Experience, shows a photo and
explains that cloth filters can be cleaned with compressed air in charcoal
gasifiers, and washed with water for wood gas with filters of other
design. </STRONG></DIV>
<DIV><BR>the cyclone looks badly out of proportion. i doubt the swedes
would<BR>get this wrong, so maybe there is an inner tube that is the
actual<BR>spin cylinder. maybe they did this to get the big wide bottom
catch<BR>basin while also protecting the user against hot surfaces. </DIV>
<DIV> </DIV>
<DIV><STRONG>The large crude proportions, were to separate charcoal sucked out
of the ash box, so not designed for fine particulates</STRONG>.</DIV>
<DIV> </DIV>
<DIV>there are many well considered features on this unit to
achieve<BR>compactness. it shows many generations of product refinement to
fit<BR>the car mounting. it is a long way from a raw series of
tanks<BR>connected together by tubes. but what else would we expect from
the<BR>swedes . . .<BR></DIV>
<DIV><STRONG>Charcoal gasifiers can be made very small, because without
condensing moisture, the cooling and filtration becomes much more simple.
Failure to design for condensate cooling with raw fuel systems will cause a lot
of grief if you pick up the wrong ideas for the wrong type of
gasifier.</STRONG></DIV>
<DIV><STRONG></STRONG> </DIV>
<DIV><STRONG>Hope this can clear up the way forward for those who are
copying these systems.</STRONG></DIV>
