<font face="Trebuchet MS">Dear Rolf, and 'Gasifiers',<br>
<br>
Happy new year to you all!<br>
<br>
Perhaps what we have developed is what you are looking for. A
demonstration and test plant is operational in Oldenzaal,
Netherlands. <br>
<br>
It is a carboniser (200 kg charcoal/h), using only approximately
5% of the available wood energy as process heat. Residual heating
capacity is 800 kW (on NCV). Flame temperature is currently
controlled below 950 ºC with a large air factor. Adiabatic flame
temperature at stoichiometric conditions is 1600 ºC, so with the
appropriate air factor (± 1.4) the flame temperature can be
controlled at 1300 ºC.<br>
<br>
Suitable biomass feeds is anything from chips, nut shells, to
chops (provided reasonably homogeneous: not chips and chops
together).<br>
<br>
Have a look here:<br>

Dear Paul, Doug and others,
to answer some questions:
I live and work in Mallorca,Spain, where we would set up a test rig.
The kiln is not jet built, but we would try to find something siutable in existing ceramic
factories on the spanish mainland, close to both granite and/or slate residues and biomass.
This 1. application is about the great devellopement of a friend of mine, a ceramist.
She invented a process to use the thousands of tons of hazardous waste from granite quarries,
like cutting and grinding sludges and others to make a high quality ceramic which has granite qualities
but is designable as porcellane.
She also invented a process for the huge amount of waste (95%!) in slate production to convert it into
a slate which is mouldable,hard, water proof and can be provided with nailing holes or other kinds of hooks.
Both are also apt for other uses.
The thing is that both need high temperature and would benefit from oxidative/reductive baking.
In the actual economical context of Spain, she could not find any manufacturer willing to venture into
this, surely partly due to lack of imagination and of course lack of knowledge about high temp.biomass firing!
She doesn't have the capital to solve either, so I offered myself to find information on the list.
I strongly believe in her process and am sure the products will find a place in the market.
( a hard, frostresistant slate ready to "nail on" would be great!)
Could someone else be interested in joining us/her? We are honest folks (rare species)...
What I have is an old open core downdraft for almond shells used on a 70 hp Dodge during or after WW2.
That sounds like 200 kW/th or more, right?
What I need for first trial would be a burner to achieve the necessary high temperature.
I could find or build a simple kiln to make some trials .
Any suggestions?
Thanks for your interest
Rolf
