When one considers gasifier thermal operations, the production of HAP's
may occur, but they should be removed prior to engine operation as an
example, or else they will foul the engine. If the gas is combusted,
the HAP's contribute to the heating value of the gas because they are
large molecules and have a good heating value. The method we use for
reintroduction to the reactor is very simple, but is considered
proprietary.

All tar can be burned in the reactor without

it?

from the gas stream and recycle it back into the reactor for

Can somebody elaborate the usage of Tar (waste(??) of Biomass

process to nano fluid as Tar is complex carbon compund...

Dear Arnt,
When we distill wood vinegar, actually very little tar comes to
the
collection tank, rest of the tar either stays in the pipes (has
to be
cleaned every month). This collection is done while the wood or
briquettes are drying in the chamber. Wood vinegar has no tar,
for soil
enrichment and ph control, it is diluted with water 1/100 or 200.
It can
also be used as pest control if diluted 1/300-500, just spray on
the
leaves and fruits. About 5-10 cc is put in to bath tub to clean
the
body, it is the main ingredient used in detox pads. When the wood
gas
start coming out, the chimney which is connected to the retort
chamber
is closed and we start burning wood gas in retort's fire chamber
to keep
heating the wood until the gas is finished, by than wood become
charcoal. If this wood gas could be harnessed, as Tom says there
is a
huge amount of energy is there.
So far I have tried couple of ways but not successful, and still
trying...
Regards,
Robert

Dear List,
we have tested wood vinegar as a pesticide on plants. It works in
the
case of moderate infestation, but if the infestation is severe,
especially with sucking pests such as mealy bugs and woolly
aphids,
one has to use a conventional organo-phosphatic systemic
insecticide.
Biochar has never worked in our local soils, which have pH higher
than 8.5. Wood vinegar has a number of organic acids in it, which
may
be used by the soil micro-organisms as their carbon source, so
that
they multiply their numbers. That the population density of soil
micro-organisms is positively correlated with soil fertility, is
a
known and accepted fact. Therefore, any treatment, which causes
the
soil microbe population to rise, would automatically result in
higher
soil fertility.
Yours

Hi Dr Karve,
As this particular line of discussion is relevant to work of my
associates, I would like to offer some comments that may be of
interest to yourself and others who use the term biochars for
soils enhancement. I also have personal interest as a organic
citrus grower (in past years), and there is some relevance to put
reason behind certain failures.

As an acid, wood vinegar cannot penetrate the waxy type coating
of "some" pests. From experience (not with wood vinegar), you need
to add a surfacicant, which wets the infestation through it's
protective coating. This is a simple as adding a liquid detergent
to the spray mix. I have no recommended ratio, but you can see it
work when the spray wets the insect. Most phenolic compounds will
kill or upset the insect to detach and leave the feeding surfaces.

If the soils are already containing high levels of carbon or
micro-organisms, what you say has relevance, but key here in this
type of discussion, is the type of char being used. Most char
readily available as a waste stream and dumped as soil
enhancement, is of the wrong type to provide a habitat for soil
micro-organisms, being made to maximize the carbon content and
density for smokeless cooking. This is the type needed for carbon
sequestrian to maximize the reduction of atmospheric carbon. Soil
bacteria on the other hand, need safe habitats, and this type of
carbon is of the activated type, with huge internal surface
porosities. Other than providing a habitat, the carbon also
provide the means of holding nutrients in soils that might not
retain them if applied just to the soils.
Therefore, any treatment, which causes the
soil microbe population to rise, would automatically result in
higher
soil fertility.
I am 100% behind your conclusion, and hope the work that many are
devoting their soil research work, can add to their knowledge from
the flow on effect, of gasification technology.
Hope this might be of interest.
Doug Williams,
Fluidyne Gasification.

Gasification friends,
It's been a while. Turbulent times for me here in Dayton, Ohio.
I
received a call from John Guthrie a couple of weeks ago. He told
me that he had
sold the land he wanted to sell me, to a company that makes
pellets. He said
" Katrina took all of our small trees". I thought he said
Pallets and
didn't know what he was calling me for. Then he mentioned a
chipping mill now
being built there. After I got off the phone I realized you don't
need a
chipping mill to make Pallets. I remembered pushing him in 2005
to bring a wood
pellet mill to Wiggins because the pulp market was glutted. He
didn't know
much about wood pellets.
I did a search on the web and found out what happened to my
need to
create a job for my tree shear with the pulp business glutted.
LOL

Check it out. Maybe he will send some pellets north on the Kansas
City
Southern, the railroad company that brought him to Wiggins in
1948. A the time
Wiggins grew cucumbers and sold pickles.
You never know what will happen when you start promoting
Biomass
