tell ya a story from monday. I had been burning wood in the hotblast with the warmer temps but it got cold, AGAIN :mad3: . so I wanted to switch back to coal. I got home about 5 to a few logs burnings yet. figured great, start loading with coal. well, I was in a hurry. had to go back to work to set the toilet in the bathroom where I just did a tile floor and had firemen training that night. so right away I loaded a bunch of coal, saw a few blue ladies, and filled her right up. while upstairs eating dinner, BOOM! what the *&$#%*$# was that the mrs asked. went downstairs and the ash pan door that was cracked was blown right open and a 15 foot stream of ash on the basement floor from out the ash door. guess I was loading it too fast. needless to say the fiance was not too happy bop2

Try keeping the loading door cracked open a little next time you do a fast load. The over the fire air will take the gases up the chimney no more BooMs Just don't forget to close it

That's usually the case with an experienced coal stove operator.......Rushing gets you into trouble! (we all occasionally try to fill our coal appliances to quickly & not burn off volatile gases...... with the same messy results)
I actually have not had a single puff-back (in 2 years now) by simply taking the extra 10 seconds to make sure I leave active flames burning above the col bed. (I don't think it's even possible to have a puff-back happen when flames are present??........Anyone ever have such a thing happen?)

Fifteen feet of ash? That has to be some kind of record. I have made several "booms" with my new Harman SF260. If the ash clean out door on the stove was closed, it would blow open the chimney clean out door. If the ash clean out door on the stove was open, it was more of a poof and a dusty cloud in the basement. Thank God it was in the basement. I can't imagine a fifteen foot stream of ash. The answer for me was over the top air through the loading door spinners. I am sure the day will come when I am in a hurry and will load the Harman too fast and/or forget to open the spinners and I will receive a loud reminder that haste makes dust. Joe

My biggest sent my baro damper out of the pipe!
along with the chimney cleanout door getting pushed
open.
it is a bit unnerving though, but the more experience
the less it happens... and yea,, haste makes boom.

With the hopper feed, I am not loading a bunch of coal all at once. I get prety good wooofs from opening the draft a lot all at once. I do have flames present when it wooofs, almost every time. Opening the door a little when opening the draft up does eliminate the wooof, just like it does when covering the fire all over with fresh coal.
:shock:

I had a pretty impressive explosion with my Model 82, it shot blue flames out the vent on the loading door, blew fly ash out of every seam in the pipe, blew the chimney cleanout door open, and blew ashes out the bottom draft inlet. I will never know if the ashes would have made it 15 feet since they blasted against the side of my oil boiler. After that I modified my technique and didn't have any puff backs for a few months...until I got in a hurry one day. I shook the stove down, filled it up with coal, opened the ash pan door and took my ash can outside to empty it in the field. When I was walking back to the house I saw a big cloud of flyash puff out the top of my chimney :shock: . I went down in the basement and saw the evidence...ashes everywhere! :mad: After that one I had enough, I leaned a cinder block against the cleanout door and put a small clip on the bottom damper, so when the automatic damper closes a small amount of air can still pass through the stove, preventing the buildup of gases.

Well, explosions are one thing, but what impresses me is that mudman has both a wife and a fiance, in the same house, yet! I'm surprised there aren't a lot more explosions.

Hi guys,

Weird things are happening here. I have been idling the stove all day and when it's time to recharge the fire for the evening/night I open the ash door, set the timer and wait until the blue ladies to start their dance. Well, a couple of times it's taken forever for the coal bed to recharge (10 - 15mins) and when the blue ladies finally show up it's been with a mighty whoosh and a pretty big puff back. The ash door has been pushed further open and flyash has gone everywhere. I have not added any new coal at this point. I’m just waiting for the coal bed to get hot and the blue ladies to start dancing so that I could actually mess with the fire. That's the first rule right - only mess with a strong fire.

Has anyone had this happen before? When I opened the ash door there were no flames in the stove, the coals were producing a stove top temperature of 200* - it was a perfect idle. It had been 10 to 12 hours since I added any new coal. Each time this has happened I have been using pea coal. The baro is set on .04 but has barely been moving with the warmer temperatures.

Has anyone else seen this or have any ideas why this is happening? Thanks, Lisa
