Ideal stack temperature for gasification/airtight style arch

[doocat]

Can anyone give me info on the above? What is too high? what is too low?

Thanks

Lots of theories here. About 2' above my arch I have a probe thermometer that runs close to 1400. Yes I burn a bunch of wood, but I make a lot of steam.

We like to run around 1000-1200. Refire around 850.

We have one of the stack thermometers you get from Leader and when it goes beyond the 1000 deg mark there is only a "F" to signify that you are looking at farenheit. So last season we came up with a new term- When you put the needle all the way past the 1000deg mark and it is pointing at the F, you just "dropped an "F" bomb"

3x10 or 3x12 force five runs around 800

Thats my goal this year,,,800, I hope I get that with the blower going !!

I will see soon I hope.

If it's a straight up forced draft arch you're going to want to see 1,000 to be boiling fast enough. Force 5's are 800 or lower because they have to have a heat exchanger of some sort, reclaiming flue gas heat to preheat their injection air hot enough to achieve fuller secondary combustion.
