After reading about coal stove explotions on this forum-here are my findings. After burning coal for the past 2 months at different high and low settings, burning coal well below hopper and into fire bed (36hrs). I have always just loaded coal completly over top and never a cough and within seconds had blue flames.
I am looking for everyones opinion, but here is why I believe I have never had an explosion.
After burning 12-24hrs-
1- MPD is closed 95%, dont open, has not been opened since I started coal stove!
2- Shake stove for about 10 seconds, not touching anything else on stove!
3- I fill by coal bucket up, slowly open hopper door (to quick and smoke may come out) and fill hopper.
4- Open ash door and may shake 2-4 seconds till I see glow and small red coals fall, close or empty tray (2-3 days till full)
5- Top off hopper and close lid
6- Blue flames are always there or there within seconds. (On a 36hr+ burn and re-filled with 60-80lbs of coal, blues were there within a minute)
In my opinion, the reason I may not be getting any backfires is that I keep a tight draft and by keeping MPD mainly closed I am not PULLING gases to strong threw coal bed while loading and re-igniting at a large amount. I have also found that while loading and after I see blues that if I open frt door blue flames start to die down within seconds, like blowing them out? Dont no if this make sense to anyone, but stove works great and have never had a hick-up!
Just looking for other coal jumkies thoughts!
