Question for Blaze King burners with lots of experience.

[ohlongarm]

What would you consider possibly overfiring a BK,example would a temp of 650' taken right on top of the combustor thermometer be considered dangerous. And a flue temp taken 18 inches from where the double wall pipe enters the stovetop at 265'.This temp recorded for about an hour with a pretty good flame shown,just wondering.

This is only my 3rd year burning a princess, but I have been told on this forum that it is impossible to over fire as long as the bypass is closed and the gaskets aren't leaking. I have measured temps in excess of 800 just aft of the cat thermometer.

wow

You won't hurt the stove if the bypass is closed. 650 is just on the threshold of good heat from a steel stove. Blaze it up!

I would love to hear an overfire number for the BK but you are not even in the ballpark at 650*F.

650-700F has been winter cruising temp for my past two stoves.

Call me a weeny but I wouldn't want to see more than that on any stove I owned.

Weenie.

If I feed a load of locust into the stove I know things are going to warm up as soon as those blue flames appear.

Never tried a full load of BL yet...gonna have to do that this season. Maybe I should work my way up to it, but I think my cat would be easier to reign in than a secondary stove. I've also had some Hedge lying around for several years that I haven't even split yet. Maybe I'm scared of it.

Love to try me some osage orange.

Even running cordwood under 7% MC this year I am not seeing flue gas temps (double wall pipe with drilled hole for gas probe) much in excess of 1100dF at cold start trying to meet the smog police's 20 minute cold start limit. My flue gas probe is 22" above the top deck of the firebox on my Ashford 30.0. With the Tstat at "medium" my flue gases are running 200-300dF after 30 minutes with the Tsat on high.

I picked up a cat probe temp monitor made my VTGroup a few weeks ago, without the factory blister pack that explicates install. I am thinking about grabbing a Condor cat probe off amazon while I figure out how to run the VTGroup unit.

Essentially, my experience based opinion is you can not over fire a BK until you get your cord wood under 12% MC. If you are at or above 12% MC, reload it hot, stuff it full and run it on "high" (wide open throttle) with an active cat for 8-10 weeks of 24/7 with no fear, December 15 to +/- Feb 7 year after year up here.

I would love to see my flue gas temp get down to 265 ;-), at +8dF ambient and maintaining +90dF in the house so the wife wears, ahem, her good nightie, I'll probably be seeing flue gas temps in the 250-300 dF range for the next four months.

When you get your cordwood down to 11% please send me a PM or start a new thread. In the meantime, if you couldn't run it at wide open throttle they would have lowered the WOT setting at the factory.

Some good relies and much appreciated.With red spruce that was me the other night while I did enjoy the fire I was a little concerned and warm.Got up to 78 'had to open the door.Guess it can take it.Last night I put in 5 spruce splits and watched a great fire for several hours before reloading and turning the stat down to 2,house a comfy 73 this am.

I have limited experience with this stove compared to others but since your stove is new (new cat) I can tell you that with both my new cats I will see at least in the neighborhood of 600*F stovetop above the cat for the first few hours of a fresh load no matter what I do. This is just the result of a fresh, new cat and will go away in time.

This is what's generally referred to as an overactive cat but I personally wish mine would stay overactive throughout its life

I only have one thermometer and its mounted approx. 18" above the stove on the black pipe, its reassuring to hear some many people say you cant over fire this stove when the by-pass is engaged.

I'm reassured but is this a fact,I wish BKVP would intercede.

Drop a link to this thread in the main BK performance thread. He might have missed this thread.

If you're measuring the top of the steel firebox, then those temps are nothing. If you're measuring atop a convection deck... 'nuther story. I can't see your sig in Tapatalk, so I don't know what stove you're running.

What is the concern? Didn't you replace a same sized BK stove with this new one? 650F stove top is not unusual.

Just wondering what the limits might be on this beast,at the temps I described it was throwing massive amounts of heat,granted the temps were only low 30's. I used a Kintrex infrared thermometer and hit the dot right on the cat thermometer,650ish,the stove front next to the door was in the low 500's. I had So much heat out put still at my disposable it made me wonder.With the front door open three feet and about 15 feet from the stove it was more than warm. And only using red fir which feels light as a feather to me.

Yes, these stoves are supposed to burn low and slow so it is a bit odd if you didn't want it that hot. Would you say this behavior is quite different from the King stove it replaced? New cat + rapidly off-gassing wood maybe? How low was the thermostat set? The next time the stove is cool do the dollar bill test on the door gasket.

The stoves door is 100% tight all around it's new been burning about a week ,I probably had more air that I realized probably at about the 5 O"clock area,only had 3/4 loaded with red spruce.Now when I want a show I lay 3 splits east west,and 3 north south plenty of flame going on with this criss cross stack.Incidentally when I turned the stat down to 2 the load burned for 20 hours ,cat thermostat at 11.Nothing to complain about here for sure.The air control on this thing is mind boggling the sensitivity of it.

That sounds good. Pilot error then?
