Looks awesome Gek, take it outta baseheater mode, check damper closed, fill her up to the bottom of the door, open your primary and secondary and wait for the blue ladies, then back to baseheater mode and adjust from there. You should see your exhaust temp go way down after awhile in base mode, like 110-160 in there somewhere.

Ok.....loaded it up full.....got probably 38 lbs of nut in....she's topped off.

Once "Mrs Crawford" gets back up tp temp, I'll post her parameters.

Going just as planned and exactly as you guys have said.....time for an icy Heineken !

Ok, I have set up Mrs. Crawford for the evening.

Dang she throws off some crazy heat!

Full load of Nut.

Set in base heat mode.

Check damper closed.

MPD closed.

.09 WC draft measured after MPD.

Primary air, about 1/8 inch open.

Secondary air, 1/3 the way open.

450 on the barrel.

225 on the exh after the MPD, 14 inches past the breech.

:punk:

Now sit back and see how your coal consumption will drop to get that level of performance.

Nicely done. Unfortunately it'll be almost 50* this weekend. "Fortunately", winter ain't over yet. :)

Looking good. ;)

Will it need that much secondary air the entire time - or is that only for a short while after loading up ?

I know right!

But just think of all the coal I saved everybody by doing this... :funny:

I'm not sure Paul, this is new to me.

There are 4 small holes the size of a dime that allow the secondary air in, so right now the total area between the four holes is about the size of a dime.

Unlike the other stove, the Crawford will produce flames throughout almost the entire burn. You will be burning a whole lot more of the Carbon Monoxide to Carbon Dioxide than before, therefore; a tiny bit of secondary air will be needed throughout the combustion cycle.
With mine after the fire is established and the stove is at the temperature I want, then I close the secondary air to just a tiny bit open and leave it there.

We'll this morning has been interesting...

9 hours after top off the parameters are the same except the barrel temp climbed up 490 ish and the stack had gone down to 150*

Bingo ! Congrats - it's a keeper !!!!! :D

Now, you can experiment and with a bit of tweaking, hopefully you'll get it up around 5:1 barrel to stack temp ratio. Then it'll really be pulling the heat out. ;)
