Using radiant heat  from refractory (ceremics)
There is something  about the performance of the ceramic panels which burn 
gas for the   production of radiant  heat.   They run at about 1000F
I  believe these panels would be capable of cleaning the gas leaving the 
production  zone of  a down daft gasifier.
A simple experiment would be to run  a panel on dirty gas to see if there 
is any improvement in the appearance of the  gas being burned. Like an 
invisible flame!
I am thinking of slicing up an  auto catalytic converter to make some super 
filters.
These of course would  need to be installed sufficiently close to the gas 
producing area 
in order  to prevent condensation of any tars which might build up, 
poisoning  the  filter.
For this purpose a little secondary air might be needed.

Hi  GF,

Once the gases have formed and exists in a free space above the  bed, it is 
unlikely to change due to the influence of refractory radiation. My  
understanding of this situation, is that you add more air to oxidise and  
combustion any hydrocarbons turning smoke gas into CO2 (cleaner emission), or  like 
in a gasifier situation, pass it through an incandescent carbon bed at  
temperatures over say 1,000C> to enable the thermal disassociation to take  
place in a reducing environment. You end up then with the smoke gas being  
(theoretically) all producer gas hopefully hydrocarbon free (:-).

I was  informed that some steam locomotives in South Africa were converted 
to the  type of gasifying principle and was used as an example of 
gasification during  a conference there about 1985 from memory. I have a photo 
somewhere in the  files.

Hope this helps.
Doug  Williams,

travel on the  footplate of a steam locomotive at full regulator, you might 
observe a  temperature of 2,500 f in the fire box. in which there is generally  a 
 refractory (brick) arch above the grate which extends the flame pattern 
and  generally helps the secondary air entering above the grate to insure 
compete  combustion. I have observed these arches to glow bight Yellow, the 
surface of  the brickwork actually  melting with the heat. I am certain the 
radiation  has a  lot to do with complete combustion. Would this form of 
radiation  help refine "smoke" (gas) breaking it down into short chain Molecules?
