Kiln Heat Exchanger Advice

This product must have seasoned wood less than 20% moisture content as it is a wood gasification log boiler.

You will only get the good gases being burnt off in the secondary burn chamber with dry wood.

If you burn wet wood you dry steam out of the wood, get a smoky burn and end up with pitch inside the heat exchanger tubes. 

Those customers use a small proportion of the dry wood produced from the kiln as the fuel for the boiler to dry all the wood in the kiln itself from one batch to another.

The airflow temperature is typically 120°C for kiln drying.

Our installer has fitted a number of these for kiln drying and there is lots of information on their web site about this product and application see

I hope that explains.

Yes, I was asking how the kiln in the video is going to work.  If it heats the logs but doesn't vent the air or extract the moisture by de-humidification surely the end result will be lovely soggy warm logs just as wet as when the kiln is switched on?

Air drying would be a better choice, most kilns are anything but.

I agree entirely, but our staffing tool a serious hit earlier in the year due to covid, so we are playing catch up and having to force dry semi-seasoned timber that would otherwise have been split and seasoned over the summer.  Not ideal but if we leave the cord out unprocessed over the winter it will be too far gone and wasted, so having to compromise a bit.  Trying to do it as best and least wasteful as we can.

What about a big polytunnel, you could put one up in a matter of days. Solar kiln innit.

Again would be ideal - just don't have the space.
