Title: adding a tall chimney
Post by: JDfarmer on February 07, 2016, 08:25:44 PM
I had to add a tall chimney to my boiler for the smoke to clear our house (or my wife was going to kill me and put me in the boiler, or make a BBQ); boiler about 100 ft away but in the woods.
I saw a picture that someone on this forum added 4x 4ft double wall pieces. Well, in 2013 I did the same. Added 4x 4ft double wall stacks, with guy wire anchors into the concrete pad.
I just wanted to update all of you, because some pople were concerned that the boiler may over heat from the extra draft.
So, I change my seal every year, and I had zero problems. I mean my boiler works perfect. I put a clean out T at the bottom of the chimney, but I don't even need to sweep it more than 1x a year if even. I burn 60% coal, 40% wood, may be that helps.
Anyway, thanks for everyone's help and input.
No smoke, happy wife...
Actually, the extra draft is nice when I open the door. All the smoke just disappears.

Your not the only man threatened to be placed in his boiler.  Glad you got everything sorted out and everyone could help.   :thumbup:

I found that if you don'nt over load your stove it dose'nt smoke that much! it gets burning cleaner faster

Very true. I tried to explain that to my wife ;)
Actually my boiler doesn't smoke that bad; but we are in the thick woods with very tall trees, and the smoke gets trapped between the trees and the house. As long as I get up to 20 feet with the stacks, no smoke at all. It all clears the house.
I originally had 5x 4 ft stacks, but I managed to make it fall over when I was tying it down, and one section got all busted up. So, now I have 4x 4 ft pieces. Apparently, I didn't need the 5th :)

Called a temperature inversion, I’ve seen the smoke come out of mine, come back down, flow down the hill and across the 16 acre pasture. Looks like fog when it does that.

Last year on one of the 40 below 0 mornings, my smoke went up about 30feet, then went perfectly flat and headed down the road about a mile staying together and not spreading out. Hoping not to repeat the 40 below this year...
