Fan CFM Requirements 9 Years, 5 Months ago  
Does anyone know if there are any CFM/bdft guidelines?

Good question. I think there are many proper airflow rates depending on the type of wood and where the wood is in the drying cycle.

I attended the VT solar kiln course in '07 (http://www.cpe.vt.edu/drysolar/) and the course information indicated that 100 to 150 fpm through the stack was appropriate. To get from fpm to cfm you have to figure out the square feet of sticker space between the boards. The answer for the vt kiln discussed in the class resulted in about 1500cfm.

I've also seen fpm numbers from 125 fpm up to 600 fpm. Take a look at this page (http://www.woodweb.com/knowledge_base/Selecting_Fans_for_a_Solar_Kiln.html) about half way down for an explanation of calculating the cfm based on 125fpm.

My kiln has three fans with each rated for 500cfm max. I'm not sure what they actually produce in real world conditions. What I do know is that I hope to improve air flow through the stack with some baffles for the ends of the stack. I'll update the construction pages for that change soon.
