Back from holiday traveling. Ended up "not" staying overnite, and returning to my stove, which was unattended for approx. 8 hrs. Before I left, the stove was running strong and hot. (Had been for a couple days.) I scraped the grates clean, M/Td the ash pan, and refilled the hopper, in preparation of many hrs of neglect. Remember, even my horizontal stove pipe was now (for the 1st time), void of any accumulated ash anywhere, even around the MPD. This was my most optimistic accomplishment, hoping for longer burn times.
I returned from my 8 hr Christmas excursion,
....to a "DEAD
I don't get it. Even the hopper was still 1/2 full of unburned coal, meaning it probably wasn't running more than a few hrs, before it died. My settings hadn't varied much from normal either. I do notice now that the MPD has been scraped clean of ash, I can't get the draft any lower than -.06-07., even with the MPD slammed shut. As a matter of fact, the other nite I went to bed, "with" the MPD closed totally, (and the draft recording a somewhat high -.06), and awoke the next morning (approx. 6-7 hrs) to a fire "almost" dead, but recoverable.
So far, to sum up this seasons lessons, I'm not so sure the Blaschac coal was any different than the coal contractors brand this season I'm using. Also, even tho there was a noticeable accumulation of ash in my stove pipe, it's not the culprit to my inconsistent burn times. I'll end up using this stove this way for a while, not expecting it to go any longer than 3-4 hrs with-out riddling. I believe my last hope of any improvements will be to "somehow" add a baro-damper behind this beast, as the manufacturer has recommended from the start. In conclusion...HAPPY NEW YEAR, to come.
