Stack Temperatures Hand Fired Stoves

Modern and vintage hand fired coal stove are similar to a wood stove and in some cases can burn either. They need to be regulated and fed by hand usually every 12 to 24 hours depending on your usage. They require no power to operate making them ideal for rural settings with long power outages.

Is there a way to adjust the back flapper so it doesn't open as much or for as long a period of time?

depending on the placement and shape of the intake flap I have seen anything from a brick to a coal hod placed beside it to limit the amount the flap can open.

time is still going to be a variable, because the stove will still have to heat up enough for the flap to quit TRYING to open.

That's a neat idea with the brick. I've got a couple friends with this stove and they are strict on there routine with it. They do the major shakedown once a day along with a few minor ones while adding only a little coal. They do it so they don't ever really have to bring the back from adding a lot of coal and getting it back up to temps. This must be the reason why. I run my stove the same way. I think because I've watched them with their stoves for years and being a veteran wood burner; I like to tinker with something after 5 hours of doing nothing. I like to shake the stove a little every 5 hours or so while I'm home on the weekends, and then I'll add 2 scoops of coal. I never really let it completely run for 13-15 hours anymore although I've done this many times. I really enjoy do little stuff to the stove more times throughout the day. I notice virtually no heat loss as the shaking is done for about 1 1/2 minutes, then adding some coal, then shutting the stove again. I don't see it drop like I would if I added 1/4 or 1/2 the coal.

Yes, and no. Yes, you can simply turn it down, or off, and use ash pan door vents. But, that's not how the stove was engineered to run. No other adjustments. You simply need to fine tune your stove operating / tending procedures. Head for work knowing you are going to have a house to come home to.

I ask because I noticed the other day (and today) that my stack temperatures shot up to 600 degrees (internal probe thermometer appr 24 inches above stove and MPD closed) when the stove was given some air. This is the Hitzer with the automatic damper on the back so it adjusts the air automatically. I could hear the flames going up the stove pipe. Maybe I just never noticed it because I'm not always here.
Normally my stack temp sits a bit under 200 degrees. Maybe I just never noticed the stack temp rising that high before as I'm not always home to see it.
Is this is a normal stack temp for a hand-fired stove? Thanks
very high. if I saw 600 F. on pipe 24" up, would probably be standing in smoldering ashes of house.

OP topic stack temps hand fired
my Harman last 2 days, no mpd, no baro
1/2 turn open draft, 550 F. front face, 250 F. exit flange most of yesterday
3/8 "--------------------- 400 F. "------------- 200 F. " overnight 7 hrs & morning wakeup
3/4 "----------------------600 F. "------------- 230 F. today 1/2 hr only then back to 1/2 turn set
efficient-yes

exit flange temp is approx 1/2 front temp this setup- if ever at 600 F. exit, would bury tmeter 1000-1200 F. front- overfire cond

edit add one, 45 degrees outside today, topped off, set draft 3/8 turn open at 2:30 PM, left house, got back 5 PM:
350 F. front face- 150 F. rear flange. could rest my hand on flange

ready for this. last night dampened off 3/8 turn open draft knob- 11 PM, went to bed.
got up 4 AM check:
3/8 turn draft knob-400 F. stove face-150 F. exit flange back
opened draft slight to 5/8 turn open, plug in fan, let on, back to bed
get up 6:30 AM it was:
500 F. stove front, 160 F. exit flange back. could touch exit pipe.
fan pulls out heat, pushes into room, cools flue. efficient.
raked down, no coal added, same setting, climbed to:
600 F. stove front, 180 F. exit flange back.
no mpd, no baro.

Hey Dusty which stove are you taking these numbers off of in your profile?
This is only my two cents
and sometimes it is not worth that
