  Ron,


  In a TLUD it's all about the uniformity of air flow. 
  If corn cobs were cut to the same length, they just might be sufficiently uniform.

  # I think it is a bit more complex that "unifiorm length." With a given species of fuel, I think it is more a relation of relative size (that would determine pressure drop and uniformity of flow across the fuel bed), and surface area and diameter of the fuel particle. (That will have a large impact on fuel burning characteristics.) 

  For example, consider a TLUD running on wood spheres of say 1/4" daimeter, and 1" diameter. Such stoves would have quite different operating characteristics.

  Best wishes,

  Kevin





  Thanks.

       Anyone have any data on using corn cobs in char-making stoves?  The supply would seem to be large and likely low cost..
