I do not believe that 70% porosity is a realistic number. Pellets
work very well and are certainly with less porosity.<br>

Dear Roberto and Stovers,
<div class=""><br class="">
</div>
<div class="">It is an interesting design that preheats the
secondary air and gives it some velocity. I would think the
flame front would be hard to keep uniform with the obstruction
in the center. They also mention that the packed fuel is best
when there is 70% porosity for achieving the proper airflow.
Determining Bulk Density and Particle Density this can easily be
determined. I’m also thinking adding in carbon densities may
also be useful to determine the energy in the primary flow. They
mention the size best being 40 - 50 mm chopped. So I am thinking
more ‘cube like’. shaped particles. Otherwise the size is not a
good measure to estimate porosity because shape will have more
to so with porosity than size. They also mention moisture as
being important. </div>
<div class=""><br class="">
</div>
<div class="">So just in this article we have a list of important
measurements for the fuel useful if we want to optimize the
combustion and as indicator of the stoves usefulness in a
different location. Also what pre-prep may be required of the
biomass at hand to be used in this stove. </div>
