I run a interior gauge that Jon(Tapper) put me onto a few years ago. It is a Condar Flueguard and here is link:

I would guess that you could get a little higher running a bigger blower but one key is would be directing the air thru smaller holes underneath the grates vs stanard grates they have a lot of space for the air to flow thru the large slots. You are not going to be able blow a ton of air thru a stanard arch or it will blow ash everywhere.Quote:

What size smoke stack do you have? I test boiled with water and had a stack temp of 1000 degrees without even trying. That's with no blower. Just natural draft. I have 10" stack, 13 feet tall. My thermometer has the probe that goes into the flue through a hole. I bought it from Bascoms.Quote:

You know when you have good draft when there are no ashes to clean out under the grates at the end of the season(or during).
Just for clarity I do not use the probe thermometer into the stack. I have the one screwed to the outside surface of the stack, so my temps may be a lot lower. I record 550 to 700 degrees F as normal. Sounds like I could get higher numbers with a probe. I use this just as another indicator of how the rig is performing. Kind of like gauges on your car dash.

I fired my new 2x4 with a blower Saturday and found I was pushing 900 on the stack and could not open door to fire with out backing the blower down first. After experimenting It appeared to me to be boiling faster with blower at half throttle is it possible that with blower on high I was not holding my heat inside the evaporator but rather blowing it up the flu?
I ran the evaporator yesterday firing every 5 minutes and kept stack temps most of the time between 1500 and 1650 and boiled off 660 gallons in 10 hours startup and shutdown included. Firing every 5 minutes kept the stack temp more consistent and steady.
Does anyone know what the relationship is with the temp of an internal themometer vs. an external one i.e. a magnetic stick on type?
In other words does anyone have both or tried both at the same time.
I just have the external version and was wondering how to adjust for the actual internal stack temp. TIA
Yes thank you for mentioning that. mine usually runs best at 6-650. I have no air either and thats what I get at the top of the base stack on the exterior ones. I get a really really strong boil all the way through my flue pans!!! SO I am happy without force air.Quote:
