Hey
As most of you probably know, I just VERY HAPPILY replaced my VC with an Osburn 2400 Woodstove.
After first fire with just bits of kindling to let it off-gas, adding 2 small pieces and air cut in half, she's already at 500 degrees ! I see no problem when I load this baby up.
QUESTION: SECONDARY COMBUSTION + Thermometer Placement
1) Thermometer. I have a small magnetic type. Not sure the best place to put this one. Ont he VC it was simple, in the back away from flame. But the Osburn 2400 really flames evenly, and the central part next to the Chimney gets the most. I PLACED IT more out front in the left corner. Thinking? it's best to have more of the average projecting heat temp instead of where flame could be falsifying the temp....... THOUGHTS?
2) SECONDARY COMBUSTION.
First Fire:
NO REAL LOAD OF SECONDARY FLAMES UP TO - PLEASE READ
Very small build. Burned right away on Full Air. Got up to 400 fast. Added larger kindling and this burned for 1 hour. Temp dropped to about 300.
During this time there was good flame in the box top and bottom, and you could see the Torch Effect up top with orange flame (not yellow).
Now a small bed of red coal - I then added a small 2" round and small split. Got it firing well and turned off the air. The flame went nearly out, but you could still see the top grab the little flicker and Torch it. But soon needed more air for a bit. It did let me turn off the air when the temp came back up to 400 or so. I then turned Off the Air and let it coast.
The wood DID burn because it turned white and the coal under stayed red, but there was very little to no flame in the bed or up top.
This burned around 400-450 for 1.5 hours. I ranked the coals forward - a good red bed. I added 3 small splits East-West and 2 Medium/Big splits diagonally (18 inches I found too long for N-S)
I could not turn the air off as the fire went out. Opened the air 1/2 and cracked the door - Bang now we are flaming. Closed the door, left the air 1/2 got near 30 minutes. Got temp to stay around 450. Flame was good and could see some Torching up top (but not yellow, and not what I'd call swirling around the top, just flickers.)
Turned off the air. Drastic flame drop. But temp stayed and wood continued to turn white. But no Top flaming.
As it burned over the next 2 hours (to present) the temp would raise to 475 and after it burned down a bit, more flame now dances in the box and when the top catches it you can see the Torch effect noticeable, but not excessive or swirling, and orange (not yellow).
EVENTUALLY -- WHEN I LOOKED in the box, I am now seeing No Flame, then wait a second and a blanket of soft red flame will swirl up from the bottom and hit the pipes and then do the Torch thing . But it’s not a constant flame swirling in the top because only intermittent flame waves are coming up from the wood ((When I had the VC this was called the wood off-gassing, this was the gas to burn, but if it puffed it meant not enough air—- If I open the air , I\ll get a faster burn…...........ahhhhhh)) [/b]
I GOT 4 HOURS SO GREAT (just not much noticeable Secondary Burn)
____________________________________________
***** SECOND LOAD UP -- 30% *****
____________________________________________
So, loading about 30% it kicked in, 450 degree, Full top of stove in Flame, Torching.
BUT 2 Hours later the wood is now a heap of coal, no flame and temp dropped 100 degrees.
This should burned for about 4-4.5 hours
First no flame, now tons and fast burn-out.
I’m confused.
I thought no flame meant no secondary combustion. Though the wood still burned (more like smouldered with high temp) without flaming.
I did nothing different, everything is just as tight—- just I did leave the door open a little more at the start and let the temp get to about 450-475 before closing the Air Off (though I read some people let it go to 800 before closing down and it lasted)
Nervous feeling 8( -- though the COAL is holding at 350 for an hour..... I'm at about 3.5 hour this way. Basically an hour off and 50 degree lower than expected.
OH... ONLY DIFFERENT THING IS: first time wood was 3 small split East-West, then 2 big Diagonally. Second Time same amount of wood but 3 small E-W and 2 big ALSO East-West. Could that make the same amount burn in 2 hours when the first time was 4 hours ?
