Firewood drying time - INSANE CLAIM?

Kiln dried not as eco friendly as air dried

 

That may well be true, but for some who have limited space to air dry timber it could be necessary so they can still feed those hungry children waiting at home.

 

Some people use waste wood to fuel their Kiln, so perhaps eco-friendly in some cases, particularly if they are supplying people who normally use fossil fuels to heat their homes.

My experience certainly says that wind is more important than heat in the summer months. Our logs are not as dry this year as they were last for similar species and drying time. Lovely warm summer for us but almost no wind unlike last which was quite cloudy, less warm but a fair bit of breeze. Can still dry logs over the winter months. Last few years have been able to sell white woods processed in September before winter was out. No chance with oak and chestnut though.

 

This may be to do with the limiting factor being the speed of migration of water within the log rather than the air's ability to evaporate it from the surface.

It could be if the heating was a by product of doing other work!

the pack fix system does work,,,

both air dried and in the kiln too.

 

to answer question, not insane claim.

So to summerise, the claim from JAS P's customer that hardwood logs pack fix wrapped up on the exposed windy hill covered on top can reduce to a moisture content of approx 20% after 3 months in the winter months - could be correct?

yes

 

done it

[arboriculturist]

yes

 

done it

 

I'll keep hauling the logs up the hill then - thanks

[Duffryn]

yes

 

done it

 

I would have no reason to doubt Bob on this. He knows his stuff. You would be surprised on how quickly significant airflow alone in summer temperatures dries logs so long as there is great ventilation all around.

I have observed that the biting cold wind we usually get coming from the East in Feb, March and into April.

Can strip moisture very very fast.

And treequip really "nails" it, per H&VAC Engineers, tis all about "air changes" per hour

 

But how many more cubic metres are there in a howling winter wind compared to a still summers day?

 

cheers
