Thomas R Miles (1916-1997)
Consulting Design Engineer 1947-1997

Dad's first experience with bioenergy was as a kid splitting kindling for
the family stove in a logging camp. Later he "punked fire on the donkey" -
stoked wood to the steam winch used for yarding logs. He worked in the
woods through high school and college. After designing airplanes during
WWII he returned to the northwest. In 1947 he opened his office in Portland
as a design engineer. For the next fifty years he contributed to the
development of product and process design in many industries. He made
important innovations in materials handling in the wood products industry
and in the preparation and feeding of combustors and gasifiers.

He attacked practical industry problems with new ideas, energy and a
distinctive style. In his inimitable manner he developed innovative designs
that worked. What he didn't design or inspire he provoked by playing the
curmudgeon or the "devil's advocate," which he enjoyed. Confronted by a
challenge he would "grab it by the face," as he learned in the woods.

He always looked at the entire system or process to develop solutions. A
good example was when he combined his talents as a chemist and engineer to
lead a study of alkali volatilization and deposition that has benefitted
many boiler owners and operators burning wood and agricultural residues.

His last project was the design of new systems and equipment for feeding
sugar cane bagasse to a pressurized gasifier for the Biomass Gasification
Facility on Maui. The hot gas will be cleaned and burned in a gas turbine
to generate electricity

On May 1 he lost a year-long battle with cancer. To the end he generated
new ideas and designs, even for the hospital equipment that served him. He
captured the affection of his doctors and staff with his respect, his
stories and his humor.

He generously shared his knowledge and experience in papers and
presentations at many conferences. He inspired and supported the
development of the bioenergy lists as a place for industry, academia and
government to exchange information and ideas.

We invite you to make a contribution in his memory to the Center for
Renewable Energy and Sustainable Technology (CREST) for the support and
development of the bioenergy lists.

Dear Ascuncion:

You said: "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 havn't heard of these two models, but they are probably for UPDRAFT
gasifiers, operating on coal.

In the 1983-85 period (at SERI, now NREL) we made a PREDICTIVE model for
stratified downdraft biomass gasifiers, based on the facts that 1) the air
strikes unburned wood first, reacts in flaming pyrolysis to consume most of
the tars 2) these gases then pass over the charcoal and are further
reduced. The model predicts the length of the flaming pyrolysis and char
reduction zones. It is summarized in the "Handbook...." and
"Fundamentals..." books listed below.

I am currently writing a book for NREL on the science and engineering of
biomass gasification. I haven't yet done the chapter on modelling, but I
would appreciate hearing from you (all) on models you have liked.

I was puzzled by the reference to "commercial" models. Maybe I should put
a price on ours!

Good luck, TOM REED

PURPOSES OF THE BIOMASS ENERGY FOUNDATION PRESS

Biomass energy and particularly biomass gasification is a field where
publications are often difficult to find. Our aim is to make available
information on biomass at reasonable prices. We list here our newer
releases and current titles and include an order form. We will also make
available at $0.15/page other papers from our extensive library of
technical papers on gasification dating back to the turn of the century.
We also act as a clearinghouse to locate technical assistance for biomass
projects. Thomas
B. Reed
HANDBOOK OF BIOMASS DOWNDRAFT GASIFIER ENGINE SYSTEMS
T. B. Reed and A. Das Over a million wood gasifiers were used to power
cars and trucks during World War II. Recent concern about cost and
availability of liquid fuels has reawakened interest in this technology.
Yet, after a decade of interest, there are only a few companies
manufacturing gasifier systems for specialized applications. The authors
have spent more than 12 years working with various gasifier systems,
primarily at the Solar Energy Research Institute (SERI). In this book they
discuss all the factors that must be correct to have a successful "gasifier
power system."

Chapters in the book include: Principles of Gasification; Gasifier Designs;
Gasifier Fabrication & Manufacture; Gasifier Fuels; Instrumentation &
Control; Gas Testing; Engine Adaptation and Operation; Gasifier Systems;
Safety & Environmental Factors; and Decision Making. The book was
originally conceived as an aid to farmers and mechanics who want to build a
"home gasifier" to power generators, pumps, tractors and mills. However,
it has expanded far beyond that scope to be a major reference for anyone
interested in producing power from wood and biomass wastes. 200pp
$25.00

FUNDAMENTAL STUDY AND SCALEUP OF THE AIR-OXYGEN STRATIFIED DOWNDRAFT
GASIFIER - T. B. Reed, M. Graboski and B. Levie. In 1980 the Solar Energy
Research Institute initiated a program to develop an oxygen gasifier to
make methanol from biomass. A novel 1 ton/day gasifier was designed and
studied for five years at SERI on air and oxygen. Now a 25 ton/day
gasifier has been operated on both air and oxygen. This book describes the
theory and operation of the two gasifiers in detail and also discusses the
principles and application of gasification as learned in eight yearsby the
author-gasifier team. Initially published by DOE with lavish
illustrations. 250pp........ .$25.00

CONTAMINANT TESTING FOR GASIFIER ENGINE SYSTEMS - A. Das Long engine life
and reliable operation requires a gas with less than 10 mg of tar and
particulates per cubic meter (10 ppm). The simplified test methods
described here are adapted from standard ASTM and EPA test procedures for
sampling and analyzing char, tar and ash in the gas.
32pp.................................. ..$8.00

TREES - Jean Giono. While we strongly support using biomass for energy, we
are also very concerned about forest destruction. This delightful true
story says more than any sermon on the benefits and methods of
reforestation. 8pp.. ...$1.00

TREE CROPS FOR ENERGY CO-PRODUCTION ON FARMS
Anyone interested in using biomass for energy should know about the
enormous potential for raising trees along with food crops as an energy
source. This book is reprinted from a conference held by the Solar Energy
Research Institute, convening experts in this field to evaluate potential
crop species and to examine practical systems for the
economical production of energy from wood species. 260 pp

Thanks for reference (even though it is coal and old). In general
gasification is to MAKE electricity, not consume it, but in special
situations a little electricity can make a LOT of energy, so my mind is
open.

Dear Sid Green or Jim Gibb:

I have been an advocate of oxygen gasification of biomass to make methanol
since 1974, the first fuel crisis. I worked at the Linde company, now
Praxair from 1952-19960, so I know a lot about oxygen.

I operated a 1 ton/d high pressure oxygen gasifier at SERI/NREL from 1980
to 1985 and my colleague, Prof. Graboski, started a company, Syn-Gas Inc.
to commercialize the work. He operated at 1 ton/hour oxygen gasifier.
I am enclosing our book list which includes 250 pages on these projects
mostly in...

"FUNDAMENTAL STUDY AND SCALEUP OF THE AIR-OXYGEN STRATIFIED DOWNDRAFT
GASIFIER - T. B. Reed, M. Graboski and B. Levie. In 1980 the Solar Energy
Research Institute initiated a program to develop an oxygen gasifier to

theory and operation of the two gasifiers in detail and also discusses the
principles and application of gasification as learned in eight yearsby the
author-gasifier team. Initially published by DOE with lavish
illustrations. 250pp"

It is relatively easy to gasify biomass in a stratified downdraft gasifier,
since the oxygen first meets the biomass and burns the tars in a fuel rich
environment which avoids the usual high temperatures associated with oxygen
combustion.

If you have further questions about oxygen operation, please feel free to
write/call/fax.

Yours truly, TOM REED

Dear Tom, Dear All:

I was sorry to hear from Tom Miles Jr. that his father had passed away - I
had looked forward to listenting to his wisdom at many more meetings. I
was very glad that TOM JR. gave a SHORT list of his accomplishments. I
knew Tom Senior a few years before I met Tom Jr., and knew that I had found
a major resource in biomass that was without challenge. There is an
earthiness to biomass, growing out of the fields and forests that can't let
us forget our origins, and TOM SR came out of reality into science. So,
although I recommend applying as much science as possible, we should do it
only after we fully appreciate the reality that Tom Sr. grew up in. I hope
Tom Jr. may give us a more extended version of his father's life and
contributions when he has had a chance to think about it.

However, there is one particular achievement of Tom Sr that Tom didn't
mention: Tom Jr. Tom Jr. has been doing an outstanding job here at CREST,
keeping our conversations flowing smoothly and sweetly (mostly) and
occasionally contributing some engineering from their vast storehouse. And
of course, Molly Miles gets equal credit for that particular act of
creation of TOM Jr. Hi, Molly! Without Tom Sr and Molly none of us would
be here at CREST.

So, TOM will have a double job now: speaking (from the archives) for Tom Sr
and speaking from today for Tom Jr.

What a family!!!

Yours affectionately, TOM REED

char gasification (in steam or CO2, and how these tars compare to tars
formed during wood gasification). Or does anybody have any comments on that
topic. I expect there to be a difference between the tars from high yield
char (high volatile content) and low yield char (low volatile content but
highly reactive)...?

Thanks

This has been a major theme in the gasification network and the world of
gasification. On my world trip last year it was a major theme in
gasification. I was horrified to find out how much diversity of opinion
and methods there is.

Dr. Tom Milne (milnet@tcplink.Nrel.gov) at the National Renewable Energy
Laboratory has undertaken to write a major study on this. We both know
more than can fill a book, let alone an E-mail.

I will have a chapter on gas cleanup in our forthcoming book (A Survey of
Biomass Gasification).

First I'd advise you to go back and search the CREST gasification archives
for tar. Then if you have a specific question, we'd be glad to answer.
Otherwise, you'll have to wait for book or study.

Waiting, .... TOM REED

Dear Tom and all,

I did as advised and searched the crest gasification archives.
Unfortunately, I did not come across anything relating to my particular
question (which is not to say that there may not be anything but telling
from the subjects, it did not look like it).

I am not actually after general information on tar formation (etc.) during
gasification (although I am new to gasification (and this list), I have
read through a number of publications and am aware that it is a wide
ranging topic, too large for an e-mail). However, I could not find anything
on "tars formed during CHAR gasification, depending on the carbonization
conditions". In other words, I want to know if the tar problem is reduced
(or shifted...) when one first makes char and then gasifies it rather than
directly gasifies the biomass. Char again can be made in say a kiln, under
mild conditions, allowing for secondary reactions, giving a high yield or
under more severe conditions but giving lower yields. As the high yield
char has a higher volatile content than the low yield one, I expect
differences in the amount and type of formed tars, during the gasification
of this char.

Has someone any useful information on this? Or am I missing the point
somewhere? I am grateful for any useful comment, please remember that this
is a new area for me.

Thanks for your help!

Markus M Benter

Dear Marcus:

Absolutely, making charcoal first enormously reduces the tar problem in
gasification. Prior to World War Ii, most small gasifiers used charcoal
and had minimal filtering systems. However, they found that the low
efficiency of charcoal production (40% of the wood energy in the charcoal)
was rapidly depleting the European forests, so they took the extra steps to
be able to burn wood. You will find this story in GENGAS. (See list
below).

Cooking charcoal, made by pyrolysing at 400-450C, still contains 20%
volatile matter. Going to higher temperature will reduce tar even farther,
but at considerable cost in efficiency.

I am still working on your other request for present status operating LARGE
gasifier systems.

Cheers, TOM REED

BOOKS FROM THE BEF PRESS

PURPOSES OF THE BIOMASS ENERGY FOUNDATION PRESS

Biomass energy and particularly biomass gasification is a field where
publications are often difficult to find. Our aim is to make available
information on biomass at reasonable prices. We list here our newer
releases and current titles and include an order form. We will also make
available at $0.15/page other papers from our extensive library of
technical papers on gasification dating back to the turn of the century.
We also act as a clearinghouse to locate technical assistance for biomass
projects. Thomas
B. Reed
HANDBOOK OF BIOMASS DOWNDRAFT GASIFIER ENGINE SYSTEMS
T. B. Reed and A. Das Over a million wood gasifiers were used to power
cars and trucks during World War II. Recent concern about cost and
availability of liquid fuels has reawakened interest in this technology.
Yet, after a decade of interest, there are only a few companies
manufacturing gasifier systems for specialized applications. The authors
have spent more than 12 years working with various gasifier systems,
primarily at the Solar Energy Research Institute (SERI). In this book they
discuss all the factors that must be correct to have a successful "gasifier
power system."

Chapters in the book include: Principles of Gasification; Gasifier Designs;
Gasifier Fabrication & Manufacture; Gasifier Fuels; Instrumentation &
Control; Gas Testing; Engine Adaptation and Operation; Gasifier Systems;
Safety & Environmental Factors; and Decision Making. The book was
originally conceived as an aid to farmers and mechanics who want to build a
"home gasifier" to power generators, pumps, tractors and mills. However,
it has expanded far beyond that scope to be a major reference for anyone
interested in producing power from wood and biomass wastes. 200pp

FUNDAMENTAL STUDY AND SCALEUP OF THE AIR-OXYGEN STRATIFIED DOWNDRAFT
GASIFIER - T. B. Reed, M. Graboski and B. Levie. In 1980 the Solar Energy
Research Institute initiated a program to develop an oxygen gasifier to
make methanol from biomass. A novel 1 ton/day gasifier was designed and
studied for five years at SERI on air and oxygen. Now a 25 ton/day
gasifier has been operated on both air and oxygen. This book describes the
theory and operation of the two gasifiers in detail and also discusses the
principles and application of gasification as learned in eight yearsby the
author-gasifier team. Initially published by DOE with lavish
illustrations. 250pp........ .$25.00

CONTAMINANT TESTING FOR GASIFIER ENGINE SYSTEMS - A. Das Long engine life
and reliable operation requires a gas with less than 10 mg of tar and
particulates per cubic meter (10 ppm). The simplified test methods
described here are adapted from standard ASTM and EPA test procedures for
sampling and analyzing char, tar and ash in the gas.
32pp.................................. ..$8.00

TREES - Jean Giono. While we strongly support using biomass for energy, we
are also very concerned about forest destruction. This delightful true
story says more than any sermon on the benefits and methods of
reforestation. 8pp.. ...$1.00

TREE CROPS FOR ENERGY CO-PRODUCTION ON FARMS
Anyone interested in using biomass for energy should know about the
enormous potential for raising trees along with food crops as an energy
source. This book is reprinted from a conference held by the Solar Energy
Research Institute, convening experts in this field to evaluate potential
crop species and to examine practical systems for the
economical production of energy from wood species. 260 pp

Hello,

Kvaerner Pulping Inc. (former Tampella Power Inc.) in Finland owns the
rights to the U-GAS technology
but decided in 1996 to give up development of the pressurized gasification
technology. Therefore they gave the
rights to the inventions - which are related to R&D work in Enviropower
Inc. (1989 - 1996) - to the inventors.
I have now all rights to my invention and therefore i am now looking for
companies, which have still interest
to pressurized gasification technology. I would be very gratefull from
company names and addresses.

My invention
&Method for Feeding Air to the Fluidized Bed Reactor
&
eliminates the problems, which
inhibits the commercialization of the U-GAS type gasification technology.
The invention:
* eliminates ash sintering problems in the bed area
* increases carbon conversion (reactivity of the fines).
* ensures stable cyclone operation (no gas back flow through the dipleg)
* ensures efficient control of the agglomeration temperature.

I have 10 years experience on fluidized bed technology and in Enviropower
Inc. i was also responsible for
analysis of all gasification test runs in 15 MW pilot plant (Tampere,
Finland):
* 15 coal test runs (Polish coal, Kolumbian coal)
* 1 lignite test run (German lignite)
* 8 biomass test runs (woodwaste, bark etc.)
* multifuel gasification (Danish straw, Kolumbian coal)
* several cold model test runs.

Dear Gasification Colleagues:

Tom Miles Jr recently asked a very important question about fluidized beds
vs circulating fluidized beds.

I have been surprised at how few communications we get from the
GASIFICATION members. Are you all lurking out there, hoping to get answers
without revealing your knowledge (and ignorance)?

I keep all letters received in this node in a (compuserve) file. So far we
have had 54 messages since August 1996. I believe there are about 60
members.

Isn't it amazing that my folder on climate/weather contains 93 items. This
is something we can't DO anything about, but we love to talk about it. On
the other hand, gasification is something we are supposedly interested in,
our contributions move the field forward, and we are strangely silent.

Puzzled.... TOM REED

We have done some recent testing using rice straw.
Rice straw is a difficult fuel to burn efficiently.
Although we have found slagging to be a concern at higher temperatures,
it can be used as fuel. The PRMEnergy gasifier has a design that
inherently burns isolated zones at higher temperatures for extended
periods.

Tom,

As one of the lurkers in gasification-cyberspace whom you are
addressing, I am compelled to reveal myself. I fairly recently
finished my doctoral studies on a batch-loaded biomass gasifier-
combustor but am now in full-time employment in research in the field
of Artificial Intelligence. I subscribe to gasification (and stoves
and bioenergy) in case one day I return to work in the field. I read
as much as possible on the subject, and stay subscribed. The list
helps me keep up-to-date. I hope one day to be able to contribute.
For now I shall continue to lurk and beg your indulgence.

Yours silently, David Beedie.

Thanks for the lead.

ive written to PRiMEnergy and hope to get some good info from them. do they have a web site or an e-mail address i can write to? ive looked but i cant find one. its faster to communicate over the web than by ground mail and cheaper than faxes (student budget!).

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.

Dear Mark Paisley and all Gasifier Members:

It is nice to hear Mark Paisley's opinion that the CFB is more compact than
the BFB. Mark is the research arm of the FERCO pyrolytic/combusting
gasifier now being tested at a 5 Mw scale in Burlington Vt., target of a
visit from the August Biomass meeting in Quebec.

I have felt, without making any calculations, that the CFB has MORE
external surface area and heat loss because:

1) It has a higher L/D aspect ratio and
2) It has a whole extra return pipe of not inconsiderable size.

Weighing against this is the fact that the superficial velocity

Vs = [(m3 gas at NTP0/(effective cross section)]

is said to be about 5 m/s - but is this calculated only on bed diameter or
bed plus return pipe?

Mark, Can you please give us the Vs of your lab unit and the Burlington
unit (or at least the figures from which to calculate them?) What is the
schedule for your tests in Burlington?

I would certainly appreciate it if you other FB people could send some
figures on your units for comparison. Ultimately they should form a table
in our book.

Mark: I notice that your email came to bioenergy - not gasification. Are
you a member of gasification? If not, why not join and we won't bother the
folks at BIOENERGY.

Yours TOM REED
