Hi, just a thought here but I have a Englander wood stove that has a ceramic honeycomb in the heat chamber. After stove is up to temp you close the bypass plate ad the exhaust gas go thru this honeycomb and are reburned. Would something like this work for you?

Good thought - I had investigated that, but from what I read, the catalytic combustors will get ruined with coal soot/smoke. Too much sulphur and other nasty compounds will render the palladium that coats the ceramic useless.
Thanks.
Thanks.

Here's a very interesting patent from VC on secondary combustion, incliding a retrofit device - mostly for wood stoves, but might be the same concept for coal.

It appears that due to simplicity and space, most stoves achieve primary burn and heat exchange in the same place, but it's inefficient, because your cooling the very space you want to keep hot. But wnen you try to separate them, stoves get complicated, big, costly, harder to service, etc.
