Almost every book on thermochemical (biomass/solid fuel) conversion has
this definition. If you are after something more specific, please explain.

Perhaps I need to explain my request further. I am referring to the
industrial process of gasification in which a solid fuel is converted to a
gaseous fuel.

I am looking for a description (definition) of the "real world" gasification
process that can be used for almost any audience. I talk to both technical
and non-technical people who are not familiar with the process. I thought
that someone might have a good way of describing the process that would make
it easy to explain to technical and non-technical people.

Any help is appreciated.

During the gasification process, the carbon contained within the coal is
partially combusted, forming carbon monoxide gas. This gas can then be
fully combusted elsewhere -- say, in a gas turbine engine. This allows
a solid fuel to be used in a wider range of applications than would
otherwise be possible.

Because the gasificaction process releases significant quantities of
heat, this coal gas is generally to hot to be used directly. In many
modern coal gasification processes the gas is cooled by water which is
evaporated into steam that can be used to drive a steam turbine or for
some other process use.

One of the advantages of the gasification process is that the total gas
stream mass flow rates are significantly lower than those for full
combustion. This means the polution removal equipment can be smaller
and less costly than for polution removal systems located in the exhaust
stream.

Both Texaco and Shell have been working on coal gasification processes.
They may have some explanatory material that would be of use to you.
You might also want to check with EPRI (the Electric Power Research
Institute) for any info they may have.

I hope this helps.

Message-ID: <000150C7.3419@mmt.com>

When explaining gasification to non-technical people and technical
managers (smile!), I say that it is essentially fuel-rich combustion.
In other words, you don't give the coal (or other fuel) enough air to
burn "all the way" and instead of getting carbon dioxide and water
vapor "in the stack" you get carbon monoxide and hydrogen which can be
used as a substitute for natural gas.

People with background in burning coal will then also easily
understand when you explain that instead of converting sulfur in the
fuel to SO2, it gets converted to H2S, and instead of NOx, you get N2
(and a little bit of HCN and NH3).

Dear Paul, powersou@aol.Com et al:

The message below concerning the definition of gasification is fine as far
as it goes. However, it leaves out pyrolytic gasification in which
roasting wood or coal releases large quantities of gas (and tar that must
be removed). The gas contains a very significant fraction of hydrocarbons
methane, ethane etc.

Pyrolytic Gasification was active in many world cities by 1850 and there
are some marvellous etchings in VIEWS OF LONDON (Dover) showing sweaty
stevedores stoking the retorts to produce gas to light London about 1850.
So don't just focus on the CO part of gasification.

PLEASE in the future make a more intelligible signaturee than "PAUL" or
"Powersou@aol.Com." It's nice to know who one is talking to.

Yours truly, TOM REED

Sasol is an original Lurgi (Germany) project, very interisting. I did not
visit it, but I was at a British Coal Gasificaton Plant quite similar to
Sasol's and another one in Schwarze Pump, East Germany, both circa 1978.

Dear list members,

I'm looking for (recent) literature in which different gasification
techniques are compared, for example Batelle, Lurgi, TPS, SHELL, etc. Any
reference or sugestion would be appreciated.

I have also another question about the different reactorsystems selected
(packed bed, fluidized bed (bubbling), circulating fluidized bed, entrained
flow or another system) in respect to the capacity of the gasifier. Can a
range be specified in which the different reactor systems are used ?
For example;
packed bed: 0 - 2 MW
fluidized bed 2 - 50 MW
Circ. fluidized bed 50 - 100 MW
Entrained flow 100 - *** MW

Thanks in advance,

Best regards,

Dear Frank,

Please let me (or all of us) know if you find such a report! I have been
looking for exactly the same information until recently. Scott Convertech
Ltd has been asked to prepare a report on the current status of biomass
gasification for CHP by the NZ FRI and one of the local utilities. I may be
able to send you a copy or part thereof, let me check. Otherwise, I have
accumulated a lot of literature. If you can be more specific, i.e. if you
tell me what exactly you need to know about which gasifier, I will be happy
to help you.

The last comprehensive study comparing most gasifiers (that I am aware of)
was published in '95 by Bridgwater in Fuel ("The technical and economic
feasibility of biomass gasification for power generation", Vol. 74, No. 5,
p. 631-653).
On http://www.eren.doe.gov/biopower/snowpapr.html you can access a paper by
Craig and Mann of NREL comparing the Battelle, IGT and TPS technologies.
Williams, Larson, Katofsky, Chen also compare the IGT, Shell, Battelle and
MTCI gasifiers (for Methanol and H2 production): " Methanol and Hydrogen
for Transportation, with Comparisons to Methanol and Hydrogen from Natural
Gas and Coal", Report #292, available from Princeton Univ., '94

Regarding your other question, maybe others of the list can help, otherwise
there are again studies out there, which have looked at that...

Frank,

I can comment a bit on your second paragraph - although I have to
confess I'm not too familiar with biomass gasification, but I am quite
familiar with coal gasification.

Rather than ranking the various reactor systems by throughput (MW), I
think it is more appropriate to rank them according to feed
characteristics. For instance, an entrained flow reactor is best
suited for low ash content feed with low ash melting temperatures (and
the feed must be finely milled so non-brittle material is not
appropriate). A fluidized bed, on the other hand, is better suited
for higher ash feeds with high ash melting temperatures (and the feed
does not have to be finely milled).

As far as size goes, I know British Gas-Lurgi had plans to build a
coal gasifier which would have fueled a large (circa 350 MWe??)
combined cycle plant. Their reactor is a packed bed, so clearly they
think packed beds are appropriate for sizes much larger than 0 -2 MW.

M.W. Kellogg has supplied a fliudized bed coal gasifier to Sierra
Pacific Power in Nevada which feeds a 100 MWe combined cycle.
Rheinbraun had plans to build a 300+ MWe combined cycle power plant
using a HT Winkler fluidized bed gasifier.

Texaco has a petroleum coke gasifier operating at one of their oil
refineries (in Kansas) which feeds a 30 MWe power plant.

So, I think all of the reactor types you mentioned can be used over a
wide range of sizes. As I stated at the beginning, I think the type
of feed is really more important in determining which type of reactor
to use.

Perhaps the list members with more knowledge of biomass systems can
comment on which reactor type is best for different biomass feeds.

PS - According to the ".nl" at the end of your e-mail address, you are
from Nederland. Do you have any information on how the Dutch
gasification power project, Demkolec, is doing? In ieder geval,
geniet het mooi nederlandse zomer weer!

Dear list members,

I'm looking for (recent) literature in which different gasification
techniques are compared, for example Batelle, Lurgi, TPS, SHELL, etc. Any
reference or sugestion would be appreciated.

Thanks in advance,

Best regards,

Frank Denys

Frank and Jeffrey,

I think the size discussion is very interesting. Frank, you suggest the
following:
packed bed: 0 - 2 MW
fluidized bed 2 - 50 MW
Circ. fluidized bed 50 - 100 MW
Entrained flow 100 - *** MW

Technically, some packed (fixed) beds are much larger than 2 MW infeed
effect, for instance the Danish gasifier at Harbooere developed by
Volund. They have put 15 MW into their updraft gasifier, if I remember it
correct. On the other hand I believe that fluidized beds can be much
smaller, less than 100 kW infeed (and I have the bench scale unit to
prove it!)

Economically, things are different. I expect a cross-over point somewhere
around 1 to 5 MW infeed effect between fixed and fluidized beds - smaller
than this point, fixed beds are more economical, larger fluidized beds
are more competitive.

Jeffrey, your approach is interesting. A characterization by type of feed
might be useful. Can you eloborate on this?

Perhaps a third way combined with one of the above might give a broader
picture: The gasifiers ability to gasify a given amount of feed compared
to its bed area, measured in ie. kg feed per second per square meter of
bed.

Do you know any investigations using this approach?

As you know, I am writing a SURVEY Of BIOMASS GASIFICATION for the National
Renewable Energy Laboratory. Volume I is GASIFIER PROJECTS AND RESEARCH
AROUND THE WORLD. Currently I have about 80 spreadsheet files, containing
the principle projects, current and some past. I have sent each group the
listing of what we know and have invited them to correct it and make it
current. Where possible I sent a fax; in many cases I could not reach them
by fax and have used snail mail.

The present list is given below. Please look it over and see if you or
another group you know of is not represented. If you wish to be listed in
the book, please let me know ASAP a contact to write to.

Thanks for your help.

Yours truly, TOM REED Webmaster

Tom,

I just received a September 1996 publication by Novem, Netherlands Agency
for Energy and the Environment titled "State of small-scale biomass
gasification technology", (EWAB 9622), prepared by BTG, Biomass Technoogy
Group. They list some 30 gasifiers in Europe and 22 outside europe. From a
very cursory look many do not seem to appear on your list. If they do they
may have different names associated with them.

The report is available for Dfl 15,00 from MHP, Management & Secretary
Services, PO Box 127, 3950 AC MAARN, the Netherlands, telefax +31-343-441936
Email: mhp@knoware.nl

Novem project contact is KW Kwant at nlnovkwk@ibmmail.com

Regards, from the Biomass Gasification Facility on Maui,

Tom,

I developed a 3 Million Btu/h, two-stage, wet wood gasifier in Vancouver,
BC, aided by significant funding from the Science Council of British
Columbia and the Canadian Department of Energy, Mines and Resouces (now
Natural Resources Canada), from 1980 through 1989.

Summary papers are given in the Proceedings of the 6th and 7th Canadian
Bioenergy Research and Development Seminars:

I attach some information on the research work that is being
conducted at DeMontfort University Lincoln UK. The work is funded by
the EU project Number JOR3-CT96-0110, and is basically the
construction of a Hybrid Wind-Biomass System for Rural Eectrical
Generation.

Hopefully I have attached a Word doc file that outlines the work.
Please note that the diagram is missing any pictures!! But I'm sure
you can work it out!!!!

JUST INSTALLED AT HUGE COST A GASIFIER. WE HAVE A DEFORESTATION PROBLEM
IN KENYA AND THIS IS OUR CONTRIBUTION. WE PRODUCE 10000000 TONS OF
AGRO-WASTE EVERY YEAR.
WHICH INDUSTRIES ARE OUR POTENTIAL CUSTOMERS?
WHICH EXPERTS ARE CLOSE AT HAND?
WHERE ARE THERE SUCCESFUL SIMILAR PROJECTS?

Best solution is generation of electricity. I'm sure you could use more
kilowatts .

Standard technology exists to burn wood waste and generate electrictiy firms
may be interested in building owning and operating such a system if you or
the giovernment will guarantee payment
