What the amounts of NOx&SOx that was created by J/batchbox?

In my humble opinion, there can not be SO2 because there is no S in wood. If we have 1200° in the bottom of the firebox, there must be NOX but as the excess of air is not big, there must not be so much.
Am I wrong?

Titanium dioxide is fomous for photocatalytic degradation of NOx. Usualy UV-ligh is mentioned, which is the energy richest light, but it also works with visible light. In a riser is a lot of energy, as temperature and radiation. Maybe the heat in a bell would still be sufficient.
I do not know how long a TiO2 rich coating would last as a catalyst. There are some other catalysts.

If we have 1200° in the bottom of the firebox, there must be NOX but as the excess of air is not big, there must not be so much. Am I wrong? Benoit From the Testo graphs on various threads, we can see that it's common to have around twice as much air as the theoretical stoichiometric amount needed for complete combustion. So I don't think we can guess about oxides of nitrogen: we would need measurements. Petrol engines in cars produce NOx even though they run at close to a stoichiometric air/fuel ratio. One of the jobs of the "three-way" catalytic converter (platinum-based) is to turn the NOx to molecular nitrogen (with the oxygen atoms being used to oxidise CO and/or hydrocarbons, or becoming molecular oxygen).
