Larry, make a copy of that post, put it in a plaque and hang it in your stove room where you can see it at every tending. 8-)
I tried putting it on the stove but it caught on fire and the duct tape melted.
Made a heck of a mess.
:lol:

Ky Speedracer, you are the E.F. Hutton of burning bit in a Hotblast.

I appreciate that you take the time to give such detail.

Here's my update and all of this is after I read your post around 4 PM.

It was @ 8-1/2 hours since the last tending.
I had a decent bed of hot coals that were clumped together.
After shaking the grates and breaking them up and spreading the coals out, I could only get 3 shovels full in to fill it.

Did not open the ash door but opened the slider on the load door completely and left the MPD wide open.

After @ 45 minutes, I closed the slider but left the MPD open.

As of 8 PM, the house is quite warm.
(It's 45 outside).
I probably won't go back down for several more hours to see what I may need to do to be ready to put the furnace to bed.

It's going to be colder for a day or two.
See how things work.

Thank you

Well, looks like I get a chance to see if I've learned enough to keep warm in cold weather.
Wednesday, they're calling for a high of 15 and a low of 5.
:o

I did a burn out and clean out yesterday and cleaned the chimney and flue pipe.
Sure like my Sooteater.
Did the whole thing in @ 1/2 hour.

8-)

Got 1/2 kitchen garbage bag of soot.
That was only in 5 weeks!!!

Hopefully, Ky Speedracer's advice on opening the slider to burn off the vols helps with the soot problem.

One last thing.

I hope everyone has a warm and toasty Merry Christmas

BRRRRRRR!!!!!!!!!!!!

My brass monkey is now a eunuch.
I hate when politicians lie to me.
They promised me global warming and what do I get?

No highs up to 30 for, at least, 9 days and negative nights.
:o

Been following KY Speedracer's recommendation.
Can't tell if it's improving heat or not.

Within the last couple days I've started trying to adjust the MPD to see if that has any effect on getting more heat.
After the vols burn off, I've closed until, either, the mano is .03-.04 or smoke comes out the vents on the doors.

Yesterday, I sat around covered in a blanket; propane kept kicking on and the coal was clumping together and smoldering.
I needed to keep breaking it up to fire well and make more heat.

Once again, I don't think I'm doing something right.

Highs in the 20s here all week. I backed the amount of coal down to About 20 percent and the rest wood and my heat has been returning the house. Still can’t get my stove pipe temp up where it was but the house is getting warm.

I never prepare with enough wood.

Just an update.

I haven't froze.

Yet.

Should be the real test the next couple days with negative temps.

Been fairly comfortable, in fact.
:)

I've been waiting to hear from you. I'm happy to see you are still amongst us, and keeping warm even. Keep up the good work ;)

Still haven't figured out dampers and how to set for maximum heat or longest burn or whether the two can be accomplished together.

Larry:

Did you ever get some good coal?

Rocks are too hard to burn and don't give much heat.

A barometric type damper is best IF you have good control of the primary and secondary air , because the chimney

can't exhaust whats not there. Power plants have huge dampers to regulate the chimney draft to avoid excess fuel

consumption .

Always had good coal.
Or as good as I can get.
:)

Tending and housekeeping issues seemed to be my biggest problems.
Still trying to figure out optimizing what I have.

I don't have a baro.
I took it out.

This recurring subject of coal had me thinking (and wondering) about something.
Ashes and clinkers and rocks.

I, now, have two different stoves burning the same coal and the leftovers are completely different.

With my Hotblast, I empty out several buckets of ashes, clinkers and "rocks" every day.

With the Warm Morning stove in my garage, I get, at most 2 coffee cans full of ashes in a cycle.
So far, I've only been burning the WM for a day or, at most, 2 days between burnouts.
Hardly any rocks or clinkers.

The Warm Morning is supposed to hold 60 lbs. of coal, so with additional coal, maybe I burn 100 lbs.

Although I don't measure it, I'm sure I'm using 100 lbs./day in the Hotblast.

The Warm Morning seems to be much more efficient.
Since it's the same coal, the (obvious) differences are the stoves.

Is it how hot one burns or how much air or just stove design that accounts for this.

If I burn more wood in the Hotblast, it will produce a more powdery ash with less rocks and big lumps of debris

Larry:::

If your burning the same coal in both stoves you can't have rocks in one and

not the other. Are you calling unburned coal rocks ?

The hotblast is a very inefficient stove in its design.

What I'm calling rocks are very hard, fused together things,
There is no black or fire left.
Just glowing and they stink and sort of heavy, dense.

I get what I call clinkers, too but they are different than what I call rocks.
They are light weight

Whatever they are, I fish out close to a bucketful everyday from my Hotblast

I also get flat tan hard things.

Here are samples of what I fish out of the Hotblast several times a day:

Larry

Most of what your showing is the coke produced from the coal, thats what you burn

after all the volatile compounds have burned away, this burns smokeless with high

heat and burns down to ash. The ash wouldn't be black but usually tan to reddish and

either chunky or sandy.

Leave all of that in the fire and bank front or back whichever you prefer with the new

coal partially covering the hot coals , you'll have to judge how much you need to be able

to burn the volatiles off for complete combustion and very little smoke , this is set with

your secondary air .
