    Its taken a while to get to this stage but we're almost there. Drawbridge style door for loading and off loading.



    Each 32"x96" rolling cart can fit two pallets of firewood, equal to 1/2 cord.

    Way more complex than the idea I had for a kiln.
    I didn't see your heat source.

    Heat source is a Nyle L200M.

    That’s an expensive unit, quick check lists it at over $7k.

    We have a kiln setup with a Nyle DH4000. Looks to be the same as the 200, just and older model. (Kiln has been in place for ~15 years) It was put in for lumber, but I needed to get firewood dry for bundles faster than the usual air drying.

    Decided to try using the kiln to see how it would work.

    Was able to fit about 5 cords in bulk bags. (16 bags) Kiln is about 300sq ft. It took about 3 weeks to dry it, cost about $600 in electricity. (Might sound expensive, but I decided that having bundles, even if selling only at a slight profit was better than not having having and loosing customers)


    Max temp on the kiln we have is pretty low. I think it can do 160*, but the dehumidifier will shut down on anything over 120* or so.

    From what I've been reading, an actual firewood specific kiln goes around 200*. Apparently at those temps, they can dry a load of wood in just a few days.

    Lumber needs to dry slow or it case hardens and splits, where firewood doesn't matter.

    Very clever. I've seen the pallets-on-rails on kilns elsewhere for side-loading instead of the big front-load doors, but not drawbridge. Why the drawbridge instead of hinge-mount conventional doors and an off-loading platform on the door apron of some kind?

    Because the area in front of the kiln needs to be free of structure, its the only way in and out of the work yard.
