I have a problem with this description because it is not a gasifier any more 
than a JIKO isa gasifier.  As I have said before, all coal fires are gas 
fires.  All charcoal fires are gas fires.

A charcoal fire is not going to burn from the inside to the outside like a 
sawdust stove does.  Nor will it burn from the top down like Reed's stove.

It will be burn like John Davies' packed bed coal stove, which is more 
technically a gasifier than Lanny's burner is.

The interesting thing about Lanny's fire is that it has a hot metal ignitor 
maintained at a high temperature by convection and radiation to light gases 
and sometimes come from the right and sometimes the left.

I have not gone into detail about the downdraft coal stove I have made for 
JHB but while investigating it I found that it the 'grate' is made from 
sheet metal punched with lots of holes, it smokes.  When the grate is made 
from thin wires, they stay hot enough and ignite what passes through them. 
Lanny has built a center-fire system that uses the wire grate of the 
downdraft stove rolled into a tube.

It is OK, it is as far as I know his idea first, but making a hole in the 
middle is not new at all, packed, unpacked, whatever.

It might turn out to be a surprisingly effective way to get the CO down, 
though I suspect it is not at the moment because of a lack of air through 
the center.  That still have to be investigated.

Best regards
Crispin
