Extracting profit from mining heat as thick slab wood kiln

[dude77]

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.

Has anyone done something similar to pipe mining heat into a wood kiln in such a way that the wood dries within a month or so without cracking?

As long as the miners are happy with their temps that should work just fine. Same goes for using the waste heat to keep a bakery proofing room warm.

I've thought for years that if I ever built out a proper facility I'd use the waste heat for a community greenhouse in winter. 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.

You first need a 100PH mining farm ... few have them.

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

My hot aisle hit about 120F at 10% humidity in the summer.  Thinking of hanging some racks back there and making some jerky!

Hope you got good dust filtration or it'd get gross real fast.
