<DIV>One system worth developing would be to conduct the (gaseous products) of
pyrolysis, "burning without oxygen" passing this "smoke " through a high
temperature reactor such as a red hot "heat exchanger" heated by the
exhaust manifold of a fully loaded internal combustion engine,then subjecting
this heated stream of tar bearing smoke through a high frequency electro
magnetic field. thus forming an ionized plasma with the use of domestic
micro wave magnetron/s</DIV>
<DIV> </DIV>
<DIV># I think I was right after all. "The best way to cure a problem is to
avoid it in the first place." :-)</DIV>
<DIV> </DIV>
<DIV>Best wishes,</DIV>

<DIV>The posibility of water shift reaction for enriching the gas with
hydrogen in this area is high, also any condensate would resemble ethanol
rather than tar. The micro wave enclosure must be made with refractory and
screen with metal ,the gas inlet and outlet screened with the same
material as used in the door of the microwave oven.</DIV>
<DIV>Because there is such enormous waste heat available from an ICE.
the pre heating of distilled water into super heated steam is easily obtained,
which will cancel endothermic reactions of water shift when added to your gas
stream. </DIV>

<DIV><SPAN><FONT size=2 face=Arial># <FONT size=3>Your very simple, but very
important question was: "What is the simplest way to reduce tar?" I feel
that the short answer is "Burn it." </FONT></FONT></SPAN></DIV>
<DIV><SPAN><FONT face=Arial></FONT></SPAN> </DIV>
<DIV><SPAN><FONT face=Arial># Support for this simplistic answer is based on
the fact most gasifiers producing low tar woodgas seem to operate with a
high reaction zone temperature. The trick is to burn the tars evolved by
pyrolysis, while burning the least amount of char. This is accomplished in
the Imbert Style of gasifier by optimal placement and sizing of the air jets
in relation to the hearth size and location for the particular kind of fuel
employed..</FONT></SPAN></DIV>
<DIV><SPAN><FONT face=Arial></FONT></SPAN> </DIV>

gasification<BR><BR>Greetings, Jai, and list members.<BR><BR>Reducing tars
in gas output, is really quite simple, design a gasifier<BR>that works
correctly for the desired feedstock is the main method,<BR>however, you
can also design a poorly built gasifier, and use many<BR>cleaning filters
after the gasifier, in the gas output pipes.<BR><BR>But really, one must
understand what "tars" are, and at what internal<BR>temperature the
gasifier runs at, once this is known, then the design<BR>can be
re-designed to achive the correct temperature to reduce the<BR>tars BEFORE
they enter the gas output area.<BR><BR>In other words, generally 2 or more
gasifiers must be built (or the<BR>original one modified) to the point of
acceptable level of tars within<BR>the gas output.<BR><BR>Greg
