Don, what would you say is the most advantageous 'non stock' upgrade you made to this beast? You've got so much info here...
Mostly, the mods I made are "Nice To Have's" rather than anything needed.
I would like to think that the insulated fan plate improves efficiency by keeping more heat in. But I have no proof of that.
The best thing you can do with one of these is match the heat output to the load, this will give you the best efficiency. I did this in very much the same way listed in the 1953 Burau of Mines report.
The Axeman is the most modifiable, tinker-able stoker boiler out there. So naturally, I tinkered, modified and Hot Rodded the heck out of mine!
Back to business...
Over the past 7 days;
Fan reading, 2445.7 - 2429.9 = 15.8 hours of fan run time, 2.26 hours per day.
39.5 pounds of rocky looking ash.
Current settings,
Fan RPM = 1460 RPM (Stock AHS is 1725 RPM)
Auger speed = 4.31 RPM (Stock is 8.05 RPM)
Grate cycles per hour = 15.11 (Stock AHS is 34.18)
Pounds per hour = Estimated ??
Aquastat = 165*F (Inkbird), ON/OFF, Hysteresis = 5*
Anthrastat = 120*F (Inkbird), Hysteresis = 0.3*
Low flue temperature cut off = 150*F, Hysteresis = 0.1*
