I burn kiln dried pine almost year round , rejects and cut offs from a molding shop. They wont take wood over 10 percent, so its dry, dry. I burn daily this time of the year, but the level of ashes NEVER goes up. Ive had about 1 inch in the fire box since last year. Dont get me wrong, not dealing with ashes daily is great, BUT where do they go? I just cant wrap my mind around them dissapearing, lol. has to be the dry wood I guess?
 
Compresses. At some point you have to empty it right?? I get much less ash with pine than oak.
 
Pine is a far less dense wood that most hardwoods therefore will generate less ash, with time and quantities ash will eventually accumulate.
 
It's not the density, maple and cherry have similar density but hugely different ash production.

It's mineral content of the wood (and bark; bark generally produces much more ash than wood - even if it's less dense).

Pine (and fir) have less mineral content.

If you want a lot of ash burn Aspen! I empty my stove at least once a week with that stuff. When I burn pine hardly any ash. I’m just about to the point of burning all Oak til next spring so I’ll probably be able to go about two weeks before cleaning ash out of the firebox.
 
I have noticed this too. Much less ash. I assume that it it less dense, and a quicker, hotter fire often results. Does the fire draft harder and the less dense ashes that don’t hold together in coal form as long get pulled up with the draft. I think I do get a more dusty/powdery chimney with pine when I sweep.i can even burn pine over oak coals and reduce the ash build up from the oak.
 
Thanks for the replies. I wish I had more ashes for a base, but im glad I have zero mess to deal with. I cleaned the fire box this summer, so what I have is a thick layer of ashes, but it never gets bigger.....weird!

I do reburn ash, with some reduction for a few days. But the oak I burn it never goes away.

Interesting. I did notice a lot of ash in the Utah stove after most burns. I'm burning at least 1/2 aspen in it. Now i know the deal. Thanks.

Walnut burns great but produces a ridiculous amount of ash
 
I'm emptying full ash pan every 4 or 5 fires with maple i think and a bunch of various branch wood. Very light and fluffy ash.
 
I took 1 shovel semi full this morning. I have about an inch left on the bottom, but its been since April that I had to clean it out.

It's why my favorite firewood is Doug Fir for most burning. I usually only have to clean out ash twice a season burning 2.5-3 cords of wood.

Likewise, the only downfall I see is I have nothing to contribute to the "what's in your fireplace right now thread" It's 99% Douglas fir.
The only other wood I can find around here that compares is Larch (Tamarack)
 
With mainly burning white pine and oak this season, I haven’t had to empty ashes yet in 2-3 weeks of consistent burning.
 
I try to take a few scoops of ash out every day or two when I have smaller fires. I sift the coals to one side, ash to the other, small fire on the coals, let the sparks in the ash burn out, scoop the ash out at the next reload. Lots of ash in my stove from aspen, the maples (& box elder), and ash. All out full load burning in cold snaps gets tough. It takes a couple of days after a cold snap to get the ash under control.
