Everything was burning good this was at 7:30 last night. Went up to the house for a 1/2 hour came down the boiler temp was at 160*. Nice red bed of coal with the blue flames dancing so I loaded the stove left the MPD open since the stack temp looked good and the temp outside was warm. Went back up to the house watched TV till 9:00 noticed the temp was at 180* coming to the house so I shut off the oil boiler switched over to the DS to feed my house .
OK, so in essentially 1 1/2 hours your stove made it from fire started to running full heat.
MPD is wide open - so essentially you are running with no damper of any kind.

Now you are loading with 110 lbs of coal. Didn't change damper setting, still running with no damper at all...

You are now 3 1/2 hours after starting fire, you've got 110 lbs of coal in the stove, MPD is still wide open, that is to say, no damper on the stove....

You have burned up 110 lbs of coal in 7 hours. Fire is essentially out, MPD is still wide open...

Mac,
You are not running your MPD correctly. At your 3 1/2 hour mark, at least, you should have closed down your MPD. That 110 pounds of coal is like getting a freight train up and running. You got your fire up and running, but never back off the throttle and just let it run away. You pumped a lot of hot air out your chimney.
The barometric damper is not the magic bullet, with all due respect to those that feel otherwise... It will help you run your stove better since you are not using your MPD. But if you use your MPD, your stove will work fine. You have a lot of draft, if you didn't you would have woken up at 2:30 thinking you were were being roasted in an oven. 110 lbs of coal holds a lot of BTUs...
You have to find the correct setting for your stove and set-up. Just as an example, I have the exact same stove as someone else here on the forums and we swap notes all the time about how we run our stoves. He has his MPD set at about 45 degress which seems to be about the same for me with my MPD set at about 85 degrees, or nearly closed. I must have much better draft on my set-up then he does. Except for loading, when I open the MPD, I typically run between about 90 degrees (or pretty much closed) and about 45 degrees. If I'm at 45 degrees, my stove is running real hot....
