Dear Yrjo and GASIFICATION:

Commens? Where are all you 60 guys (sorry, humans) listed as members of
gasification. I would like to have a short note on each of your interests and a
comment on what you would like to see more of here in GASIFICATION. STOVES
(with about 30 members) is ten times as active as GASIFICATION.

Have a great New Year and new year, TOM REED

Dear Tom,
I signed up to this list in hope of learning something--I have
nothing to add. I'm at a Thai country pottery where we're running out
of wood, but have all sorts of agricultural waste lying around which
we can't burn in our kilns. I'm curious whether it might be possible
to turn it into gas, which I do know how to burn.
The whole of what I know about gasification comes from a Scientific
American article of years ago, where some Israeli scientists built a
huge solar tower to heat biomass up to produce hydrogen. I'm sure we
couldn't do that, but it has always piqued my imagination. I just got
connected to the Internet, and am trying to use it to replace the
library I don't have available.
So that accounts for one of the inactive guys on the list.
Happy New Year,
Nikom

I need some info on filtering exit gases (after combustion) from a gasifier.
Operating temp is 1400C, so there is not a lot of stuff left in our system.
After combusting 10 tons of MSW we had only a handful of ash. But we want to
ensure exit gases are
within EPA limits. Who makes a filter system for this?

I agree with Tom: The activity is really low. This must of course mean that
we are all too busy solving problems....

Can anyone help me out on the following:

For the Danish needs a small scale two-stage fluid bed concept has been
developed. What I want to know is: Are there any commercial fluid bed
gasifiers available, and in which sizes? If I can buy it, why invent it?

On my personal homepage I put up a short overview over most of the Danish
research and development projects. I intend to add my most recent paper to
the homepage soon. See the url below.

(snip)

Fair enough.

My interest is in developing projects for the generation of electricity
and/or heat from forest residues and other sources of wood fuel,
primarily in the UK. I am therefore interested in what technology is
commercially available to do this, or might be available in the near
future.

As regards electricity generation, there is support available in the UK
for projects using "gasification-by-partial-combustion or pyrolysis" to
produce gas or liquid fuels to drive a piston engine or gas turbine.
These (potential) projects are for grid connection, and generally need
to be several megawatts to be competitive.

The main technologies which interest me are, therefore:

1) Up-draft gasification with gas clean-up

2) Fast pyrolysis

While I am interested in all the technical details and problem solving
that is going on, what I really want to know is whether anyone can make
it work reliably and put a whole package together. I have therefore not
entered the discussion up till now, prefering to wait and see what's
going on.

I suppose what I would really like to see is a list of who's working on
what in this field, with some sort of indication of how close to
commercial availability the technology is. Given that that doesn't seem
very realistic, I'm just hanging about listening to what's going on.

Happy New Year,

Tom,

I noticed Tom Miles answered already partly your question. HTW concept is a
German fluidized bed system, originally developed for lignite. Rheinbraun is
the licensor. A commercial plant was built by Uhde GmbH in the late 1980 at
Oulu (some 600 km north from Helsinki) at an existing ammonia plant. The
idea was to use peat syngas instead of heavy oil syngas. The plant was
operated only for a while, as the reduced cost of oil killed the feasibility
of this venture. However, it was a large facility (about 25 t/h milled
peat), and the largest of its kind in the world up today. Please find a few
references below.

Dear John:

"info on filtering exit gases (after combustion) from a gasifier. Operating

1400 C gases must be exiting from a combustor, not a gasifier. That is too hot
for any filter that I know of.

Gasifier exit temperatures are 900C at most, more likely 600C. One of the
attractions of gasifiers is that the gas can be filtered before combustion.
Cyclones work down to 10 microns, bag houses and ceramic candles much lower.

I will be interested in seeing what replies you get.

Yours truly, TOM REED

John, I'm interested in your problems of hot gas filtration after
combustion of the gas from your gasifier. As the fuel is MSW, I assume
the gasifier operates in the updraft mode or principle. Tom's suggestion
to use cyclones is one that we used back in 1981, but large amounts of
particulate under 10 microns still remain in the exit gas.
My concern however is what may be fixed in the fly ash, which if
discharged into the environment, or even collected becomes a toxic waste
disposal problem.

Dioxin formation will certainly have all the conditions present with MSW
fuel, when combusted or oxidised, my advisors assure me, becomes fixed
in the ash. Don't handle this stuff without taking saftey precautions.

Because you are not saying what you are doing with the combusted gas
stream, it is difficult to offer a practical suggestion or system best
suited to your installation. Can you expand on how you are using the
system?

Dear Carol,

ETA is involved in Renewables Energies and Desalination/Water Projects.
We're now wotking to a JOULE III project named DESERESCUE: it is a
feasibility study which aims to rescue arid coastal areas in
Mediterranean Countries (and abroad) by means of a bio-energy scheme.
In other words, the energy necessary to desalinate sea water is provided
by a small scale bio-energy system. The biomass tyep, considering
local climate condition, has to be some kind of energy crops.
The partners to this Project are:
ITER (Canarie, Spain): Manuel Cendagorta, Marcos Oramas
CENET (Munich, Germany): H.P.Grimm
IFP (Braunschweig, Germany): N.El Bassam
Therefore, we're very interested in these small scale systems. If you,
or someone you know, could provide some real example of these units
we'll be glad to contact him.
The generator should provide approx. 100 kW or, alternatively, power in
the range 400-600 kW.

Thanks.

. all the best for the New Year,

David

Message-ID: <3.0.16.19970129210131.32877ce6@mail.trd.sintef.no>

Hello list members

As a part of my PhD study I working on characterization of LCV gases. I
have started with laminar flame velocity (experimental and CHEMKIN) and
will continue with flame geomtry where I also plan to include radiation.
Furthermore I'm planning to look at NOx emissions from both premixed and
diffusion flames.

The litterature gives a lot of references on typical gas composition in
terms of varation area for the different components, and I also have
litterature giving the gas composition from lab scale units and larger units.

I guess the litterature I have gives a represenative picture of the gas
composition from commercial biomass gasification plants, but nevertheless,
here's a free offer. If anyone of you out there have a spesific request or
suggestion on a gas composition that could be of interest for the work I'm
going to do I would be very pleased if you contacted me.

So far I have been looking at gas composition from air blown biomass
gasifiers, but also steam and oxygen gasifiers are of interest.

Of course, I if you have comments or other information related to the
topics I'm working on , please contact me (actually I have not found that
much litterature on flame velocity and flame geometry for LCV or MCV gases
in the litterature).
