Jim, (great avatar, by the way!),

One of our older members - Mark Strickland (GaBoy), used to heat his kiln with an outdoor wood boiler.  You might check the archives to see if there is any information about it.

As I recall this was back in the 2004 - 2005 timeframe.

that would make a ton of sense with the amount of wood we all have laying around :)
I knew what I thought I meant.

Thank you, Scott.  That is "Shep", my very best friend and our family's protector.  We had to say goodbye to Shep on December 19th of last year.  He fought a gallant battle but his hips and spine finally gave out.  It's been 9 months and we still cry.

Up at 4:00 am researching kilns and how to best set this one up.  Most of the (non-solar) kilns I've seen have a dehydrator somewhere in the mix.  I'm wondering how important that is if I'm pumping in a constant supply of new, fresh 135* heat?  Wouldn't a vent opposite the side I'm introducing the heated air from force the humidity out with the exiting air?

Because of the heat losses in the garage, if the heating unit delivers 50,000 BTU, you will have about 25,000 BTU per hour for evaporation.  This will evaporate about 20 - 25 pounds of water, which is 0.75 to1 % MC loss from 1000 BF.  Note that 50,000 BTU is about 15 kWh

I'm sorry Doc but I don't know if that is good or bad?

Slow,
Any way I could contact the guy by you?
I am considering creating a kiln using a shipping container with an OWB and would love to pick his brain.
 

There is a fella not far from me that has a shipping container kiln that he heats with a water-to-air heat exchanger and a OWB.  This is a feasible way to do it but I am also positive that he supplements it with another heat source for the final sterilization and pitch setting at the end.  I am not certain what heat source he is using in addition to the HE.  He has dried and sterilized wood for me on several occasions with great results.
