Solar Kiln pile placement question2/11
Hoping Dr. Gene will weigh in here with an opinion.
If a Virginia Tech type solar kiln is 18 feet long, and a load of 10 foot lumber is going to be dried, what is the best way to load the kiln?
If the load is centered in the kiln, should the empty areas at either end of the pile be handled in a way to prevent the circulating air from "short circuiting" around the ends of the pile?
Or - should the pile be placed at one end of the kiln and a temporary divider be set up to block off the unused portion of the kiln and any fan in that area turned off?
Finally, is there a recommended gap between the bottom of the lumber pile and the kiln floor? Drawings typically show the pile sitting on bunks of sorts, and I'm wondering if a larger gap at the bottom would provide a path of least resistance for the air flow instead of the flow being pushed through the stickered pile.
The clearance at the bottom is for the fork lift’s forks. Without a fork lift, whatever distance you want is ok...minimum probably around 1”.
It really does not matter how the 10’ lumber is positioned, so long as you block the extra space. In any case, avoid too much air flow and possibly block part of the collector on a hot sunny day when above 40% MC.
