With every revolution of the gearbox the lever moves this pawl and it catches a set amount of teeth on the gear that drives the auger.
The pawl can be adjusted to catch only one tooth all the way up to 10 . But the amount of coal fed to the firepot varies from 2.5# per hour to 25# per hour.
I'm pretty sure you can leave the stoker runing and adjust your heat and fuel use with the pawl adjustment.
If this isn't clear, PM me with your email and I'll send you a photo of the gear and pawl that may help explain what I mean.
Hope this helps Greg L
thanks greg.......we got it goin! it's 72 degrees in my 3500 sq ft uninsulated garage....now mind you we got a nut burner goin, but it was 52 degrees in the shop 2 hrs ago and we cut the nut burner way back......maybe even to the scrap yard in a few days for coal money (it's a ? yr sunbeam with a huge chunk of the grate missing......we have the efm stoker set to 4 notches, we are burning buckwheat coal in it.....it was recomended by my roomates father who has been burning buckwheat in his efm boiler for years.......i switched my alaska stove that i have in my apartment over to buckwheat too....both doing well........glad to see many others are fascinated with coal heat lol........i'm not a coalcracker at heart, i moved to schuykill county pa a little over a yr ago cause i could not afford rent on a shop to build custom cars.......had 4 nut stoves running to keep the building warm last winter (it's 3 attached buildings, the garage, my roomates house, and my apartment........total of 6500 sq feet..........i'm hoping this efm stoker will cut down on my total coal consumption (i avg a ton every 10 days) when this was an auction house, they burned alot of oil......there was a 1500 gal underground tank.......i'll have none of that lol
