Outdoor fireplace
 
Ok, sorry I posted this on two other fourms I am new to the site .I started to build an outdoor fireplace. The base and fire box is built and the smoke chamber is about 10 inches from lentil. The flue is 12 X 12 and 3 feet. I burned a small fire and was getting smoke out of the front. There was a bit of a breeze however when the breeze stopped smoke and small ambers came out the top of the flue. My question is if I take a second flue and move the other one and have them side by side would the fix the problem. The fire box is 30X30 and 18 deep. I am not looking for much heat displacement. Thank you.

Outdoor FP's are always suseptable to smoking, much more so than an indoor.

In your case, it sounds like your smoke chamber is far too short.

You could certainly benefit from at 2 more feet of flue. If that's not realistic asthetically, you can also look at a decorative clay smoke pot.

Starting fire an hour or so before you want to enjoy it helps as well, as a warm chimney draws far better than a cold one.

Lastly, you're going to have to accept a little smoke at times with an outdoor FP.

Thanks you for the info. How about if I add a second flue next to the first one so there side by side. this would give 24 inches of an opening leaving 3 inches on both sides. Would this help with the smoke chamber issue. Thanks again.

Ayuh,.... Then it would heat slower, 'n loose velocity...

Bigger chimney doesn't equate to a taller smoke chamber...

You don't need more bulk air, you need more upward draft & velocity.

From the sounds of it, either your smoke chamber's too short or you've simple got a firepit with a makeshift chimney over it.........

How tall should a smoke chamber be.
