A few weeks ago, someone posted about flames jetting out of the secondary air ports on their stove. Might have been some discussion of this phenomenon happening with the DS circulator stoves that have the secondary air holes just inside the firebox door.
Noticed when I fired the stove tonight, and left the ash door open a couple minutes (while standing there, of course) this was happening with my DS 1500. I've seen it once or twice before, but my glass was clean this time, so it was pretty vivid. Had my phone handy and shot this video.
This is probably no big deal but it sure is pretty.

Nice video! I have a DS 1400 and get the same result, now and then.
My DS bi-metal controlled primary intake seems to be slow to respond after a shake down and hopper reload. Especially a bit later on. It will sometimes flare up to 600 degrees and more before shutting down for a cool down. The secondary air duct "blowtorches" seem more common with white ash coal than the red ash with lots of bone that I am mostly burning this year. Supposedly, Gale. Maybe something to do with the volatiles level?
Pretty nice to watch. Seems to really clean the glass off but a little worrisome.

Thats were I got my coal this year (Sep). I believe it was 170. a ton. Seems ok, Only my second year burning, last year I had it delivered and don't no were coal really came from.
I've burned alot of different brands of coal, I'm on my 3rd season so far. I can't say that any of it has been bad coal. It seems that these DS stoves are pretty indiscriminate and will burn all coal fairly well. If I could get some good white ash coal without having to drive far, I would, just to avoid clinkers. The RR hasn't produced too many, so Im probably going to stick with it.
Just as a recap - I've burned the following
Anthracite
Superior - Mix of red/white ash, average ash content
Mammoth Materials - Mix of red/white ash, average ash content
Jeddo - White ash, low ash content
UAE Harmony (Lykens #2 vein) - Red ash, very low ash content, high tendency to clinker
RR Coal - Red ash, average ash content, will form a few clinkers. High volatile content.
Bituminous
Valier Coal Yard - Gray ash kittanning seam, no clinkers, extremely high volatile, high sulfur, lots of smoke, difficult to control.
Cobra Mining - Gray ash, little inch seam, very low volatile, low sulfur, low smoke
Broad Top - Gray ash, broad top field, very low volatile, low sulfur, almost no smoke
