For those who don’t have perfect weather, for drying your wood gas chunks, this is what I came up with since our kiln burnt down. I’ve run 5 batches already. It takes 3 days to run a batch. It does a great job. Here are some pictures of my project.
The box is 8’ X 4’ X 4’
It is lined with 3" of polypropylene sheets,
It will hold 3 racks that I can load with my tractor. Over 500 # of chunks.
The door has 7 regular hinges, and has eye hooks on both sides so I can ratchet it shut tight.
I can attach my heat exchanger to my outdoor wood boiler using pex lines.
I used a furnace blower fan and a 14" X 14" heat radiator.
I can monitor the heat using a meat thermometer and the ambient temperature is 135* . I can regulate the temperature by the ball valve coming out of the boiler. I put a dryer vent on the opposite end to release the steam.
