[Stoves] Insulation and stove life

[Alex English]

Crispin,
Although it may not be the 'standard' a fan powered TLUD  or others 
could have the fan only applied to the secondary air with natural 
bouancy supplying primary air. This would work for pellets and fuels 
more porous than rice hulls. With the right configuration there would be 
no ash entrainment to speak of.
