Do tell...

Evening guys and gals. Been reading up on a few things that has my curiosity up. Below is a pic of my stove and piping.
As you can tell, there's not a lot of pipe there before going into the chimney, and the temps on the pipe are pretty high.

The barrel temp right now has been hovering right about 460°. The pipe temps inside/outside of the damper are 263°/307°. Inside the house its 68°, outside it 1° with a -10° windchill. As you can see in the pics below, I've got the dampers almost closed.
What, if anything can I do to maximize the efficiency in this stove? One 40# bag of nut coal will last about 40 hours if it's not too cold out. I just feel like I'm losing a lot of heat up the chimney.

Need a manometer to determine draft...

Get a mano in there and I have a pretty strong drafting chimney so I have 2 mpd in my pipe I turn each one opposing directions i got the idea from Wilson and it really seems to help slow down the gases

B,
That's a 'jumbo clinker', maybe running to hot. Try to put a damper in the vertical pipe section closer to the stove. Also, close the primary air intake on the ash drawer a little more.
Also, there are different MPD's, meaning, some have no holes, some have small holes, and some have large holes. I have found that 'small holes' works best, keeping the heat out of the chimney. I have 2 MPD's on my Herald, 1 close to the stove, and, second one close to the chimney. It works.
Cheers

Thanks guys, I'll look into the nanometer today.

Pretty sure the 'jumbo clinker' is from running too hot on Sunday. Last night when I went to bed at 11, the barrel temp had been at 460° for four hours, it was still at 460° this morning at 5:40am, having burned about 70% of its fuel and maintaining a 68° temp at that end of the house.

This mornings shake dropped the least amount of ash that I've seen so far. Reloaded and set the air for about 350° since its going to be a little warmer today.

Ok, cleaned this stove out tonight, getting ready for cold and snow this weekend.

Got a fire going about two hours ago, been adding coal every half hour, and top of the barrel just hit 400°.
Close it up and shut the light off, and see this...

Needless to say, this makes me a little nervous...

I know I’ve have a stove and before I lined the pot it would glow but now quite that bright.
Is your pot lined or just the cast iron?

A stove that is drawing that hard may have an air leak, or leaks, somewhere at, or below the level of grate area. If there are any it's like having another primary damper open.

While the stove is going, use a piece of soldering string, or incense stick, passed right up close to every seam, and all around the edge of the ash pan area door. And check for cracks in the underside of the ash pan area with a flashlight and mirror. See if any smoke gets sucked in. If it does, than seal that seam area with furnace cement.

The ash door can be sealed with high temp silicon put on the inside edge of the door and closed against waxed paper held against the stove base.

so.....what happened with this ?

I can see that if you were building the fire and using plenty of draft to help it all get going this might be the case as you shut things down to cruise mode but it should have been short lived even though the heat out put held steady.

Well I was actually in the process of reloading after clean out. G/f struck again and it almost went completely out.

It was like than for less than an hour, after I closed the bottom air almost all the way, it stopped.

Introduced by Sears in 1927 I believe.

Dude... that's awesome! Thank you!
