I know my wood is 100% dry 3 year old oak 10% moisture, but today I am getting white smoke that dissipates as soon as it comes out of the cap, I am sure it is moisture but what is causing it? my chimney has a single wall liner.

H20 is a product of combustion.

Okay - not a chemist. Where does the methane come into the equation? Cheers!

He's just being generic. A combustion reaction is a combustion reaction.

The way wood burns is basically to get hot enough to produce methanol (CH3COOH),NH_Wood said:pgmr said:CH4 + 2 O2 → CO2 + 2 H2O + energy

I've been waiting for someone to make that correction.pen said:As a gas, you can't see steam. It is technically steam as it is traveling up the inside of your chimney and it would be invisible.
If you live in Stratford Upon Avon there is no way your wood is that dry (unless you store it in a kiln).Neil said:I know my wood is 100% dry 3 year old oak 10% moisture
I guess it depends what you mean by damp climate. Anyway my point was that in a place that has a mean temperature of 47 degrees (averaged over a year) and a mean humidity of 75-80% it is not possible for wood to dry to 10% moisture content. When wood reaches a water content that is in equilibrium with its environment it does not lose further moisture however long it is left to season.BeGreen said:Why not? We live in a damp climate and our seasoned wood is just fine.

I'm not confusing anything. Equilibrium Moisture Contentpgmr said:I believe you're confusing the relative humidity of air (a rather complex number to determine - see http://en.wikipedia.org/wiki/Relative_humidity) with the simple percentage calculation of "weight of water in wood to total weight of wood". The two numbers aren't really related other than that a high RH of air might slow down the drying of the wood a bit.

If you've had it in the house a month in RH of 50% or below maybe the skin would be down to 10% but unlikely the core would be.Neil said:Well my moisture meter is wrong then, it is 3 year old oak that was dead for perhaps 50 years when cut down, has been in the sun and covered for 3 years, in the the house for about a month before burning and showing 10% ...is that not possible then
It is not a hard and fast rule. Why would you expect the condensate trail from your flue to be any different than your car exhaust? If the outside humidity is near 100% there will be fog.Troutchaser said:My breath fogged and trailed several feet behind me, the car exhaust filled the driveway with a noxious fog, and my flue had about 20 foot of steam (?) trailing over the yard..
