That's a very difficult question to answer, at least from my point of view.
To me, I don't really look at how long it lasts, or doesn't last.
I look at how comfortable I am.
I can get a really long burn, if it's 48° outside.
But not so long as when it is 3° out.
I'm not trying to be a wiseguy!
But... there are only so many BTU's in a stove full of coal.
So if your stove temp is ~300°, you may get , for example, 18+ hours.
If your stove is ~600°, like mine when it's windy and cold, 10-12 is pretty easy.
BUT... having a fire last 12-18 hours is not always great, IF you have
to very gently add coal to it, to get it cranking happy again!
Because all that time the stove drops to 275°... you are getting cold again!
So really... what works good for me, is not going for marathon burns,
but maintaining a nice happy good sized bed of coals.
When I'm asking the stove to perform, I feed it more often,
in smaller quantities. That way, the stove temp doesn't drop
as much... the fire catches quickly, and the stove has a big happy face on.
Monitor your stovetemp/stack temp if you don't have a manometer.
Rutland gauges, while not great, at least give you a guide line
for around $9.99 at HD, or Lowes.
Just make sure your stack doesn't get really hot. If it gets too hot,
you may have too much draft. A mano will help a lot,
not in fixing anything, but it takes away the biggest unknown:
how strong (or weak) your draft is...
Hope this helps a little..
There are a lot of seasoned folk here, all more than willing to help.
