Re: GAS-L: Subject: Wood gasification demo in Germany

Dear Gavin

I have stated a number of times on this forum that I had to close the
Fluidyne workshop in New Zealand in 1998 due to the lack of orders for
gasifiers.  Fluidyne gasification technology continues to be developed under
my supervision in Canada U.K. and Germany, but mainly Canada where we are
developing the larger gasifiers.  To that end there has been almost two
years now of testing to comply with the EPA emission test standards which
once completed will allow us to implement this technology for our own waste
disposal business, and at this stage we are not planning to sell this
equipment.The  biggest delays  to our work have not been technical, but
trying to get permits etc.

In answer to your question regarding duty cycle, we aim for at least 30 day
continuous operation, and passed experience has shown us that we can operate
up to 12 weeks before shut down to clean a coke that forms in the
distillation zone above the nozzles.  The other thing that affects the
reliability is the cleanliness of the fuel whereby dirt or stones form
clinkers that are difficult to clear through the grates.

Because all of our work by  the associate companies is being funded
from within company financial resources,  the development work creeps
along at snail's pace and it will be quite some time in my opinion before
one of them has the courage to offer equipment with the corresponding
warranties.  Personally I would rise to the challenge and go for it myself
and give you a quote, but those days are now passed and you will have to
wait until some other company tries to meet the non existent demand for
gasifiers.

In the meantime I try to contribute to this forum if for no other reason
than to try and contribute in a helpful way, based on experience, which
sadly there seems to be little value for when you try and extract a dollar
for technical assistance.  You will see that there is plenty of assistance
needed from the recent requests for information, all of which can be found
in the archives of this forum.

I hope this clarifies the situation with Fluidyne Gasification, which I
always sign after my name, which is Doug Williams (my son is Graeme) so that
you know my contributions are based on commercial experience.

Regards

Doug Williams
Fluidyne Gasification.
