GAS-L: Small Scale Gasifiers

["Graeme Williams" <graeme@powerlink.co.nz>]

Dear Paul & Colleagues,

It's pleasing to see the Gasification List come alive again, and what's more
unveiling the issues that each of us in our own way are trying to resolve.
With such healthy input, surely our gasification technologies can be
presented in an orderly fashion to the less informed, and where possible
support those who strive on our behalf behind the scenes.

I have to say that in our debate on small gasifiers, the addition of stoves
just doesn't fit right in my mind, although you could call them process heat
gasifiers and try and find them in the "Yellow Pages".

Here in New Zealand there is a healthy market for such stoves and there must
have been 20 - 30 different models and sizes on a display I saw a few weeks
ago.  I know the KENT brand was sold in the USA a few years ago, and they
made a big thing out of the emissions being far less than the US standards.
Possibly these types of stoves are a New Zealand development, as I know a
lot of work was done to perfect their design principle in the old DSIR
laboratories.

To read a nice explanation with diagrams, check this web page -
www.energywise.co.nz/content/pdf/demo59.pdf and hope the whole discussion on
these wood burners can be passed back to "Stoves".

The gasifier design that I mentioned can be found on the Fluidyne Archive -

I hope this clarifies some of the issues
