<div>Hi,<br>
<br>
What are the all the after effects when using wood chips in a
down draught gasifier with moisture 20% to 30% ? <b>Haven't
tried 20-30% yet, but we have been testing Albasia wood
chips ( 127 kg/m3) at 12%, still there was so much moisture
in hopper, I will try this week with 25% bamboo chips, let
you know.</b> <br>
<br>
Its opinion ed that biomass briquettes can be used in biomass
gasifier, could some one advice which is the best briquetting
process as under <b>Briquettes are made with screws pressure
about 40 tons, we use mix sawdust merbau-mahogany,
briquettes weigh 1200 kg/m3, moisture level 7-8%. If you
want I can send you some briquettes, you can try, I assume
you are in Indonesia, I am in Purworejo. Briquettes are
costly to use in gasifiers, briquette charcoal would be more
fiziable, since we sell broken briquette charcoal almost
same price as the briquettes. </b><br>
<br>
</div>
<ul>
<li>Multi variable biomass briquettes ( Rice husk, saw dust,
groundnut shell ) or Individual biomass briquettes can be
used<b> Yes they can be made briquettes but costly. We are
working on a system it would make briquettes from
household garbage to use in gasifiers. Main purpose is to
dry the waste.<br>
</b></li>
</ul>
<br>
Under what conditions could flame or burning be experienced in
down draught gasifier when in operation using wood chips. <b>I
really don't understand the question. Once you fire the wood
chips in gasifier, you have flame and and char in almost
instant with blowers. We get wood gas in 2-3 minutes</b>, but
actually takes about 30 minutes to get the gasifiers heated and
really clean gas.<br>
