[Stoves] Limiting factor for secondary burn?

[Paul S. Anderson]

Frank,

Crispin has already sent you some good comments.  There is a fine balance
between the number/size of the primary holes and the amount of draft that is
acting on the primary air.  The actual physical construction of your unit can
have a major impact.

It would be useful to have a description (words or photos) of your 
unit. Because photos are not sent via the Stoves e-mail messages, you 
could send the
written comments to all and the photos to Crispin and me for comments.

Glad that you are active with the small gasifiers.

Paul
