Dear Brian
----- Original Message ----- >
I would very much like to add a small plasma punch to our gasifier outlet.
Was sharing that thought with someone at church Sunday (yesterday) and he
suggested I look at welding equipment. And now here is Tom implying the
same thing. Two in two days.... need to think about this more....
What do you see as an advantage from adding a plasma torch to the gasifier
outlet?
Best wishes,
Kevin

Dear Tom, Jeff and all
In the 1950s I Worked at the Linde Air (now Praxair) Company and was
director of welding research for a time. We had a number of physicists
doing basic research, plus a lot of applied development work. I hold
several patents on plasma torches, and am glad to see this discussion of
the merits of combining a small plasma input to aid pyrolysis.
I hope most of this work is using graphite cathode (DC) or AC electrodes.
They are cheap, ell developed, and relatively citable compared to all
others.
Forward!

Jeff,
There seem to be two approaches to using plasma in biomass gasification:
as
an igniter and as a reformer. Two companies use the plasma as a super
"hot
plate" that they dump biomass onto in an updraft gasifier. This is the
AlterNRG approach. http://www.alternrg.ca/
http://alternrg.com/plasma_market_solutions/biomass_to_ethanol
They are able to make a gas that is low in oxygen and rich in CO and H2
while supplying only about 3% of the input energy as electricity. The
rest
is from the biomass.
There are other plasma reformers coupled with updraft gasifiers. There
was a
project proposed in Canada using this approach with a PRM gasifier.

don't know if this project has snapped, crackled or popped.
Los Angeles Country looked at plasma gasifiers for waste a couple of
years
go.

Dear Tom,
I've often thought that a modified updraft gas producer coupled to a
plasma reactor could be a lot of fun when working with waste feedstocks.
Snap crackle and pop,
Jeff
