Two-Fiddy on the Barrel and a Hundred Less on the Stack

It won't be easy at lower temps because of warm weather. With a stove that size, stove coal for a start. In all but the coldest weather, I don't think it'll breath well enough with nut coal to get there.

When it gets colder outdoors,.....
When the firepot is full and burning well and you see those blue jets in William's picture. With the check damper fully closed, play with the primary open more and let the barrel get up to about the 500 range. Then, leave the primary there. Try using the MPD to slow the stove down. Don't be afraid to get the mano down below .04.

Give it about 15-20 minutes to settle in and then check the hottest part of the barrel to the pipe just before the MPD. By closing the MPD the barrel temps should go up some. If the stove starts to slow down after about an hour, you'll know that the MPD is too tight for that primary setting. Make a note of the mano reading and open the MPD slightly. When you reach the lowest mano reading that the stove will remain temperature steady-state that's your stove and chimney set up "sweet spot".

When it gets colder you'll need to open the primary more to get more heat. Knowing the sweet spot, just close the MPD until you get the mano to read the sweet spot number. That will maintain the temp you picked while keeping as much heat as possible in the stove.

Only use the check damper when you want to run the stove low so as not to overheat the house, and/or to get longer burn times from a load of coal.

Yeah, I think I really need to get cooler weather and get back on the stove coal. The nut I have is for learning....knowing it'll be different than stove size.

At the current temps I think I have the CD figured out....I know it'll change when 'SH%T GET'S REAL'.

I don't think so. You are measuring the hottest part of the range at a point where the surface is very close to the fire. It then falls off rapidly. The average temp. will be much lower. Stoves have their surface much further away from the fire than your range. If we could measure a point just above the fire as you do with the range , then yes.

Franco,
Reading what base heater barrel to stack numbers were being reported on here in the past year I started to see a pattern. It averaged 5:1.

As a coincidence only, I noticed my range does the same, and higher. Recent test with the Kimmel's coal from Tractor Supply routinely get it running near 6:1 even with the primary and MPD closed way down. So, yes the top plates are closer but the volume and depth of coal burning is less than half that of most base burners.

However, the 5:1 is not out of place for some of the better run base heaters. Over 500 on the barrel and being able to place your hand on the stack only a few feet from the stove, guess who I learned that from ?

A few feet would be not much more than shoulder height. At 500 on the barrel, I would have to see it.

I will have to start a log this year because my memory is not what it use to be. However, last year I seem to remember during the "Polar Vortex" when we had several days of -20°, I was burning at 600° on the barrel and only 150° - 200° on the stack. This was in baseburner mode on the Kineo, not on the cook stove.

I run the Glenwood up to 600 and the stack temperature never exceeds 150 in base burner mode.

Just curious....how big is the room where the stove is?.

It's in the basement.

I was just curious on the size of the basement. I have not had mine much over 500 and that was just a short period of time. The heat coming off was impressive to say the least. At a constant 600, you must have a warm basement.

420/120 this morning.

WOW, given the size of the stove that IS impressive. For October that means you really will need that brute and soon. I got my Glenwood #9 (9" fire pot) kind if moving the other day and it was impressive. I'm getting a little apprehensive about the #8.

I think I am being held back by the weather....we've had warmish days and some cold nights but not a constant period of cold. THAT'S FINE WITH ME....not complaining...it can stay like this until March and I'd be happy.

I DO need some constant cold, though, to further hone my newly mad skilz.

How big is the room the #8 is going in?.
Mine is on the North end of the house (roughly 40ft from where we spend most of our time). The house is a 30 x 50ft two story with a full cathedral (NOT optimal for heating by any means). I have been able to EASILY maintain constant low 70 degree temps throughout the up and down weather we've been having and have not needed to open the winders.

You can really run these gals down low at constant temps. With my old woodstove, no matter what, minimum stove top temp was 450ish. That's just how the stove/chimney interacted and that's what it did.

The #8 has a MUCH larger range of operation (and it's probably much larger than I have been running it but I am still tweaking my inputs to the stove) and a much much larger potential for heat output.

SQUARE FOOTAGE IS KING (and the #8 has lots of that). I am sure a #6 sized burner would be very similar.

I rarely run the Glenwood over 450. That's is its cruising temperature where everything is optimal. The heat produced at that temperature is adequate also.

By the way....I just tried 'banking' about 2/3's of a bucket of coal. I've heard about it but never tried it. Well.......if you are gunna do that, don't go away for very long. Cripes.

...it's coming back down now. 525/180.

coalnewbie · Post by **coalnewbie** » Fri. Oct. 24, 2014 4:11 pm

Explain banking 2/3rds a bucket. I would prefer in your No 8s for idiots guide you make a movie of these mistakes in real time. Now that would be exciting, put it on Youtube..... Ashcat, what are you doing these days?
