Interesting. I wonder what keeps it from being a bit burner but allows it to burn anthracite? Bit and wood burn very much the same way but anthracite burns completely different.

The thing is, neighbors are very close to my house, and I live in a duplex. Neighbor on other side. Hah. Didn't want complaints, so I went to Anthracite last couple years.


I don't know much about your stove or it's controls but if there is any way to add more secondary air to the fire (air above the fire) when burning bit it will help with soot and smoke.

Fire pot design and back pipe design mostly.

To burn wood I have a cast iron plate that goes over the grates and their is one over fire air control in the door, works great but hard to get more than a 4hr burn out of it.

The back pipe (not quite a base burner but similar idea) is too restrictive for Bit, clogs up with soot in a few days burning. And if I bypass it I have a real hard time controlling the heat.

There's definitely a few design features that are Anthracite specific.

Thanks for the link!

Timing is everything and the timing is not good right now. That's how it usually works! But those would be right up my alley.

Well, here we go...
I started up the HBF (Hotblast furnace) last night with bit.
The jury is still out on the secondary burn tubes as of now because I was working with a Kingsford charcoal coal bed to start the bit. The bit was very stable. It ignited and burned easily and was easily controllable. The mano-guage never got above -06. The outside temp was about 42 degrees and stayed there throughout the night. Started out with about 40lbs of bit at 8:30pm and still had a good bed of hot coals at 6:00am this morning.
I shook it down and slowly added a couple of layers for a total 40lbs of Kimmels nut anthracite. The fire ignited and as everyone on here says "the blue ladys started dancing...".

At 8:00am it was *42 outside and I had 199* in the flue pipe, 343 above the load door and -04 on the mano. Secondary air is closed primary is open 1 turn. Not much activity on the baro.

At 10:00am it was *47 outside, 144* in the flue pipe, 266 above the load door and -04 on the mano.
Secondary air is closed primary is open 1 turn.

At 2:00pm it was *49 outside, 131* in the flue pipe, 224 above the load door and -06 on the mano.
Secondary air is closed primary is open to 2 turns to try and stabilize stove temp and keep it from falling.

At 5:00pm it is *51 outside, 126* in the flue pipe, 200 above the load door and -04 on the mano.
Secondary air is closed primary is open 2 turns.

The draft seems to be holding pretty steady according to the mano. But, the stove temp seems to be in a fairly steady fall only 10 hours in.
Have I burned through 40lbs of anthracite already?? I haven't shaken it yet. The outside temp is suppose to drop down to the low 30s so I assume the draft will pick up later and I can open up the primary a little and see if I can reagin some stove temp.

Completely new to anthracite here... So any thoughts or obvious anomalies regarding the info above. My assumption is the fire is not fully matured yet. Maybe a more mature fire would holed temp longer??

The pic below is of the fire early this morning.

Did you block the bypasses between the front and rear liners with fiberglass insulation??

i think you need more coal, 40 pounds isnt enough, do you have roughly 8" of coal? if not more?

im putting in 15 lbs in the morning, and 15 lbs in the afternoon right now usually.

Yes sir. Both front and rear.

I just added another 30lbs.
When I shook it down there wasn't much left.
I'll keep an eye on it and see how it does tonight and then maybe work to get it a little deeper.

Yeah, you might need a deeper bed. I've been running 250 over the load door for 30 hours, temp just started to fall about 8 hours ago. It's at 214 currently. At shake and load 30 hours ago I only added 36 pounds which built it up level with the top of the fire brick.

Also, I noticed that when I toggled between bit and anthracite, that it seemed like the anthracite burned better after the second tending. Not sure why or if it was just a figment lol

And one more thing, it could be possible that those secondary air tubes are rerouting primary air as the grates ash up. Just a thought.

we add roughly 30-40 pounds at each tend, but when we first lit it could of taken upwards of 80-100 pounds to get it full, i do not believe you have filled your hotblast yet, which is why your temps are doing what there doing, im suprised its still going.

Mr. Hotblast is correct, I just reloaded with 61 pounds to bring it back level to the top of the fire brick. Mine had burned down a little further than best case scenario.

I'm sure I was being a little cautious not wanting to run everyone out of the house by "over-heating/firing" the stove (still have my BIT hat on...). So, I didn't fill up the firebox with coal. I'm probably 3" or more from the top of the bricks now. Sounds like I completely blew "anthracite 101". As I understand it, you should pretty much fill up the firebox. Adjust your temp with primary air control. The depth of the coal is really more about how often you need to fill the fire pot...not necessarily as much about the stove temp... Im guessing I get an "F" or at best a "D-" on day 1of burning anthracite. :oops:
After I added the 30lbs of ant a couple of hours ago it has been back up to 300+ .
Currently 307 above the door, 152 in the pipe and -04 on the mano. The house is 74*.
Next tending I'll get the depth up to the top of the bricks.

we'll give you a b+ though for giving us the right explanation! lol

yes always a full firebox, you just cut the primary's back.
