Title: Extracting profit from mining heat as thick slab wood kiln Post by: dude77 on May 30, 2019, 01:16:15 PM I saw this mentioned a few times in other threads but nothing with very much detail so I thought I'd make a thread to see if anyone had done something similar.
The basic idea is to use the excess heat from a mining farm to dry thicker slabs of wood than what you can normally get at wood supply shops. Thicker slabs are more valuable to wood turners and things like bowl blanks can sell for quite a bit of money on sites like etsy and ebay. There is an infinite amount of free wood on craigslist. Tree service companies will often happily give away the trunks they remove because they have to pay to have it hauled off.

Same goes for using the waste heat to keep a bakery proofing room warm.

Fuzzy's right, as long as the miner temps stay comfy you can do anything you want with the hot air.
If the ducting is long you'll want a secondary blower to help move the air without causing a lot of resistance against the miner fans. Not sure what you'e require for thermostat controls but having a second cold-air inlet that mixes with the hot air in the ducting before reaching your kiln might be necessary to slow down drying if your wood starts to split. Shouldn't be too hard to rig up.

Otherwise you're spending a lot of money on dealing with a small amount of heat.

Thinking of hanging some racks back there and making some jerky!
