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.<br>

think it is pretty obvious that a fan-powered stove will
loft a lot more small particles than a natural draft
version. They can easily be blown up through the fuel bed.
If it is chimney-type ND stove then it is not such an issue.<o:p></o:p></span></p>
