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
I am thinking of slicing up an auto catalytic converter to make some super
These of course would need to be installed sufficiently close to the gas
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.

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.

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?
