GAS-L: Small Scale Gasifiers

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

Dear Gasification Colleagues,

It is easy to understand the confusion that exists about gasification in a
general sense as the phenomenon can be found anywhere you create fire.
However, for this interest group to include gasifying stoves is in my
opinion incorrect, as they should be identified by their correct name of
double burning or smokeless stoves which commercial manufacturers call them,
and as such stay in the stoves forum.

For people researching gasification and interested in using gas to use
separately for whatever end use, this is the one group who can offer the
most assistance and information on the subject, particularly if it is for
engine applications.  Those of us who actually work in this field of
technology have made a commitment to see gasification fulfill an important
role as a source of renewable energy and chemical feedstock.  To cross
pollinate gasification with close coupled combustion, then discuss adapting
these stoves for engines is less than helpful to those who seek accurate
information about gasification.

While it might be important for individuals to buy a small gasifier, it is
equally important for the manufacturer to find enough individuals to create
a market.  Then, instead of saying how much are small gasifiers, ask
yourself - how much am I prepared to pay for one.  This is a valid question,
so state your financial ability to pay for your commitment to renewable
energy.

Alternatively, decide on a size (discuss it with a manufacturer first), get
a quote and order 50.  Then onsell to those who just want one unit.  If this
isn't a solution for you specifically, then you have to accept that the only
way to own one, is to build it yourself.  Since I posted the design for a
small gasifier on the Fluidyne Archive last year,nobody on this list has
written to me saying "I'm ready to go, what's next?"

Last August in Northern Ireland, two French engineering students working at
ITI (Innovation Technologies Ireland) built one out of salvaged scrap steel
and I shared their excitement of having it flaring gas within 3 minutes of
ignition.  I'll see if I can find the photographs and ask Graeme to put them
up on the Fluidyne Archive - www.fluidynenz.250x.com.  This will take a
couple of days.

Gasification is very addictive and a lot of fun . . . so let's discuss
making gas and not heat, unless it's burning gas!
