I've been running a number of dry burns on my WSM 18.5 while I attempt to tweak my new ATC. Basically I load up the fire box and add 3/4 chimney of KBB. I'm running these test at 225* and 325* with the top vent fully open. Performance has been very good with respect to temperature regulation and prompt adjustments to temperature changes in cook temp. The system is working quite well and maintains the temp for hours as expected.
Part of this study was to observe any ash activity. I did this by incorporating my new stainless water bowl (thanks Chris) which is very clean and very shiney. Any ash produced floats on the water's surface and is easy to see particularly since no meat is involved.
Some ash has been observed but it does not appear to be any more significant than what a non-ATC WSM produces. However, this is not what got my attention.
At the end of these dry cooks, the water in the bowl is very dark brown, not something one would see in a standard black bowl. This isn't ash. I assume it is creosote which had condensed in the water. This doesn't bother me since I never utilize the water bowl for anything other than moisture production. But others do make gravies in this bowl by collecting drippings from the cook. This cannot be a good thing for those who consume this.
This may be common knowledge out there, I don't know but it's definitely something one should consider.
