Normally, smoke will burn or oxidize, at a temperature of 1000o F or higher.
Burning a stove this hot would require a continuous intense fire and would require a higher wood consumption.
However, wood smoke gases coming in contact with the catalyst will cause chemical changes to take place.
This will then allow the smoke to ignite at temperatures around 500o F. or (260o C.) once the catalytic combustor has lit-off.
This temperature is easily achieved in the firebox of a catalytic wood burning stove.
As the wood gases ignite and burn within the catalytic combustor, clean by-products of water vapor (H2O) and carbon dioxide (CO2) are emitted.
