<p>Hi Indika,</p>
<p>There is a reduction in CO if the gas is collected at over 500C,
due to it revering to soot and CO2. You need to quench the gas
temperature as it is extracted from the collection point as close
to the internal gas where it exits the char bed. If you can do
this, then the accuracy of the analysis will be improved. It would
be interesting to see what the other gas % is claimed by the
designer.</p>
<p>Sorry to hear that Ray has passed over. We had quite a few
exchanges about biomass fuel growing.</p>
<p>Regards,</p>
<p>Doug Williams.</p>

<p class="MsoNormal"><span>The gasifier has not been tested yet,
but the designers claim to have 50% CO in the gas with
previous gasifiers, which was unimaginable to me. When we
were speaking of sampling the gas, we have been warned that
the CO of the gas may convert while sampling. This is why I
am researching on the fact. </span></p>

The equipment is rather costly; we will have to use the
