For those who are new, Tom Reed is actually the living gasification legend
as I and many other researchers and developers benefited very much from
his books and publications. <br>
What scientific publication Doug Williams has a part from his web site to
sell world war-II downdraft gasifiers ? I do not think worldwide
Gasification community can benefit so much from commercially sensitive people
like Doug Williams. Tom Reed was the most reliable resource that the
Gasification community relied so far because he shared everything
that he discovered.<br>

Hi Gasification Colleagues,<br>
<br>
I must say I have enjoyed the recent discussions initiated by Tom Miles, that
has bought to the surface, some of the experiences which as manufacturers of
gasifiers, we face in the market place. Other than those who are only just
discovering gasification, enthusiasm to use the technology in a market
dominated by fossil fuels, is less than encouraging, but as addicts of
gasification, I guess that we believe in what we do, at least, most of the time
(:-) <br>
<br>
To dwell on the negatives however, doesn't help us to answer those asking
questions to arrive at the right or appropriate answers. While we can
point to certain successes, or technical achievements at all levels of gasified
applications, the development work to interface gasifiers in commercially visible
installations, still needs vigorous unbiased scrutiny. Not ever y thing that
whistles and shines, no matter who makes it, can be proof that it works as it
should.<br>
<br>
I'm intrigued by Colin's question of how long should a gasifier be tested
before declaring it commercial, because the reply depends on who's asking the
question, consultant or manufacturer. Each have their own set of
responsibilities. Insurances on which your guarantees may rely, especially
Public Liability, may place limitations on conditions of supply, so the market
you need, may have no protection if outside of the country of manufacture. As
you add the liabilities that may accumulate as a condition of supply, the
"testing period" needs to cover all those things that could invoke
any financial penalty clauses.<br>
<br>
For what it is worth, drawing from our own commercializing programme begun in
1984, we sent the same design of gasifier to <st1:country-region w:st="on">Fiji</st1:country-region>,
<st1:country-region w:st="on">Malaysia</st1:country-region>, <st1:country-region
w:st="on"><st1:place w:st="on">South Africa</st1:place></st1:country-region>,
and Maine USA. In the differing environments of temperatures and high altitudes,
we had to test for a base line for performance that was consistent across all
conditions, more a test of our finances than that of the gasifier. That took
two years alone, but worth the effort not to have any nasty surprises in the
remote Highlands of Central PNG. <br>
<br>
If you add to this a two thousand hour engine test conducted by Listers NZ,
before arriving at the testing of the final design, you may get some idea of
just how much time based experience is needed. Short cuts cost money, usually
somebody else's! Shiny nuts and bolts cannot fix a flawed philosophy of gas
making, but many with questions, have little appreciation of how environmental
factors can affect gasification behavior. It's not only about how many have
been supplied, but tested performance across the conditions that limit
their reliability. You just cannot do all this in the cloistered protection of
a home base.<br>
<br>
Hope this may be of some help Colin.<br>
<br>
