BIOENERGY EMAIL LISTS

The bioenergy mailing lists are hosted by the Center for Renewable Energy &
Sustainable Technologies(CREST) for industry, academia and government to
discuss biomass production and conversion to energy. There are four lists
at CREST.

o Bioenergy (bioenergy@crest.org)
Moderator: Tom Miles (tmiles@teleport.com)
(Other Volunteers are Welcome!)

Current subscribers to the lists are engaged in the research and commercial
production of biomass crops and fuels, the conversion of biomass power in
commercial operating plants, the construction and testing of commercial
scale pilot facilities for combustion, gasification and anaerobic
digestion, testing and analysis of environmental impacts for bioenergy, and
promotion and planning of future bioenergy resources.

This is a cooperative, volunteer effort that is now in it's third year. The
lists are moderated and managed by volunteers. We appreciate the support of
the Center for Renewable Energy and Sustainable Technologies and the
National Bioenergy Industries Association for hosting the lists at their
site.

Subject: GAS-L: New Zealand Gasification Process
Message-ID: <00004F46.3419@mmt.com>

Does anyone out there know anything about a biomass gasification
process supplied by a New Zealand company, I believe its name is
Combustion Consultants, Ltd.? As I understand it, they have sold over
600 installations worldwide.

The process uses a fixed bed gasifier followed by a close-coupled
cyclonic combustor to provide heat from biomass wastes (typically wood
wastes, paper, cardboard).

By the way, I am a new subscriber to the Gasification list. I am a
research engineer for Molten Metal Technology. Our company "recycles"
hazardous wastes by injecting them into a vat of hot, molten metal
under reducing conditions. The combination of the high temperatures
and the catalytic effect of the metal causes virtually any waste to
break down to its atomic constituents. We can then use these atoms as
"building blocks" to produce use products such as syngas or HCl.
while our process could be used to gasify biomass, we have up until
now concentrated on "high end wastes" such as nerve gas, unexploded
weapons, radioactive wastes, and chlorinated hydrocarbons.

Before I joined Molten Metal last year, I worked for Shell Oil Company
for 10 years and helped to develop Shell's coal gasification
technology. Consequently I have a lot of knowledge about gasification
in general, but not a lot about biomass gasification in particular. I
will be happy to share my knowledge (to the extent that it doesn't
violate my various confidentiality agreements) and look forward to
learning more about biomass gasification from the other members.

Message-ID: <v01520d00af7c34009af4@[202.37.189.128]>

Dear Jeff,

I will try to find out whether there is a New Zealand company named
Combustion Consultants or similar. The only company that springs to my mind
immediately is a New Zealand company called Fluidyne. They apparently build
small scale downdraft gasifiers...

I am however very interested in the Shell gasification technology. I am a
research engineer with Scott Convertech Ltd. We are developing a continuous
process to de-ash, fractionate (steam hydrolysis) and steam-dry particulate
biomass, in order to extract some of its components. The remainder, a
comparitively clean, low ash fuel probably consisting of dry cellulose and
lignin particles can be used for various applications, including
gasification.

Because of the way our process is designed, we are interested in entrained
bed gasification technology (such as the Shell gasifier). Interestingly,
Williams. Larson and Katofsky claim in their PU/CEES Report No. 292,
"Methanol and Hydrogen from Biomass for Transportation, with Comparisons to
Methanol and Hydrogen from Natural Gas", that the Shell gasification
technology would not be suitable for biomass gasification because, amongst
other things, it requires the fine grinding of the particles (which is too
costly with biomass). But they did not consider the greater reactivity of
biomass compared to coal, which may mean that they do not need to be ground
to the same size...?!

Do you (and anyone else) have any comments on that? And is Shell applying
its gasification technolgy to biomass at all? What is the current status?

I look forward to your comments.

Regards

Markus

Dear Jeff,

the only other NZ company that I could find, dealing with this subject to
some extend is "Waterwide". But according to our somewhat old brochure,
they build biomass burners...?

bioenergy, gasification, stoves, digestion, and bioconversion.

I think we can attach a sponsor's tag line to messages.

bioconversion)

CREST has carried us for free for three years. Now it's time for us to

Message-ID: <3.0.32.19970423073431.00ab64e0@mail.teleport.com>

Bioenergy List Members,

A point of clarification: we are not asking for or requiring subscriptions
to the bioenergy lists. This has been and will continue to be a largely
volunteer effort but there are fixed network and service fees to pay. So we
are asking for sponsors and contributors. You are welcome to contribute
individually or as a sponsor. Companies and individuals who sponsor lists
will be recognized/promoted on the list and WWW archives.

Each list costs us $50/mo or $600 per year. The five lists (including a new
bioconversion list) add up to $3000 per year.

Sponsor a list for a month or a year. We have received one generous
individual pledge of $100 for the bioenergy lists. If less than 10% of list
subscribers made similar contributions each year we would ensure the
continuation of the lists.

Tom

Bioenergy List Members

We need to raise $3000 in bioenergy list sponsorships this year. So far we
have $1500 in pledges of $100-$600 from a few generous and interested
individuals and organizations.

I hope that you are willing to contribute. It costs $50/month (or
$600/year) to host each list. We hope to create a bioconversion list in
addition to the bioenergy, stoves, gasification and digestion lists that we
now have.

Please send me a note if you will contribute.

(This reminds me a little of the local "listener supported" radio and TV
stations.)

Jeff,

Our company supplies two stage combustors similar, in principle, to the New
Zealand combustor, described mainly to the forest products industry. Two
units have been operating continuously in Solway, MN for the last 16 years
burning wet bark and direct firing two wafer dryers at Northwood
Panelboard.

Here in British Columbia particlulate emissions must not exceed 120 mg/std
cubic metre (0.052 grains/sdcf). We meet that on wood waste.

>> Does anyone out there know anything about a biomass gasification
process supplied by a New Zealand company, I believe its name is
Combustion Consultants, Ltd.? As I understand it, they have sold over
600 installations worldwide.

The process uses a fixed bed gasifier followed by a close-coupled
cyclonic combustor to provide heat from biomass wastes (typically wood
wastes, paper, cardboard).<<

The system you are describing is actually our latest development into
biomass and waste combustion. This week we will commission a new 2 MW
thermal unit scaled up from our 300 kW prototype.

We have a lot of ideas about combining our technology with a vitrification
stage and we actually had in our minds to visit Molten Metal in MA last year
to discuss these ideas - but time went to short. Please contact me if you
want further information.

Best regards

Message-ID: <199704291543.RAA12993@sarenet.es>

I am a new subscriber to the gasification list. I am an engineering from
Abengoa, an spanish company whose main activity is the management and
execution of infrastructure projects in the fields of Energy, Transport,
Telecommunications, Water, Industry and Enviromment.

In its Energy Developments Division I am dedicated to gasification research.
I have found two models for fixed bed gasifiers belongings to Brigham Young
University and Morgantown Energy Center. I will be happy if anybody could
know these programs and could tell me about his/her experience with them or
inform me about other gasifier models commercially available.

I look forward to learning from you.

Thank in advance.
