Dear Doug
Your Fluidyne gasifier and Jim Masons GEK seem to be the best gasifiers
around. Do you know of any others?

Wow! What a great report.
You mentioned that some of the wood chips had lots of fines. Do you
preprocess them to eliminate those fines? Are the trees debarked before
chipping?
Just getting started,

Hi Tom,
Thanks for your interest:
Your Fluidyne gasifier and Jim Masons GEK seem to be the best gasifiers
around.
I can only say that our current work with gasification, is repeating what
Jack Humphries and I set out to do in 1976, bring up the technology to meet
modern standards, using materials that were but a dream in 1976! As for
being the best, well, I would settle for the most reliable for whatever we
choose to do, but we are not trying to sell gasifiers to anyone at this time
(:-)
Do you know of any others?
Well, that is a curly one, for some make claims of selling gasifiers which
are hard to verify. There are many offering gasifiers around the USA as I am
sure you are aware, but to what standard other than their own marketing
hype, do they meet? All gasifiers that are offered for sale, should have a
certificate of compliance for any specific application to sort out
commercial quality systems.
We can only hope that not to many duds get sold for inappropriate
applications.
Doug Williams,
Fluidyne Gasification.

Hi Pete,
You ask:
>You mentioned that some of the wood chips had lots of fines. Do you
preprocess them to eliminate those fines?
At this time no, because we are testing how these types of chips behave in
packed beds. It's all about surface area of the fuel changing the speed of
gas making within your chosen rage of gas outputs. The rule of thumb still
applies, finer fuels mean smaller gas outputs and or gasifier size.
Are the trees debarked before chipping?
The tree tops we use are not debarked, but after drying in a log dump, much
of the bark falls off as handled. Bark in itself, is not a problem in a
gasifier, but mud and dirt in the bark, certainly can make for slag or
clinker problems.
Just getting started,
You might just be ready in five years (:-)
Doug Williams,
Fluidyne.

hi all!
I design updarft rice husk capacity 100kg/h.there is a problem tar
high,process
level of Moist.
Fuel use burn direct and no craking tar.
discontinuous and working gas is laborious, low-built efficency.there is
betterment which way neither.
thanks!

Doug ,Tom,
Although the dazzling blue flame is but the revealing icing on your
linear gasifier cake. I have a question about it. Did InstrumenTom
measure its exhaust? Numbers?
"With all gas going to the flare stack, this flow of 147 scft/min made
an impressive flare roughly 2m high. In this mode, considerable
information is obtained from the flare, especially the presence of
carbon blacks, or tars, which contaminate the feathery ends of the outer
edges."
When I see changes in the feathery ends of the outer edges, I'm inclined
to think that it is from the formation of compounds formed within an
oxygen starved portion of the flame.
If black carbons or tars where carried over from the gasifier might you
not see them glowing lower down in the flame as well?
Can you make the flare flame tips change colour by pushing it rich?
Thanks for posting the report.
Alex

Alex,
I'm preparing to gasify sewage sludge in another location today but I'll
post the numbers. The gas flame is very steady and manageable. We can easily
control O2 from about 3% to 8%. NOx and CO are less than 100 ppm.

The orange glow in the flame is incandescent carbon above 1000 C. So , in
cool parts of the unburied gases you don't see the soot. But where there is
a diffusion flame with air , it lights up.
It would be interesting to view the flme/gas structure with infra red
goggles.
