Many pellets I’ve tested do not. </div><div class=""><br class=""></div><div class="">I think a graphing of the biomass used is needed. The spider looking graph i mentioned i think will work. Moisture along one spoke starts with 0% in the center to, say, 50% on the outside. Place a dot on the spoke for the % moisture found in the fuel. Next spoke is particle size from sawdust size in center to 25cm on outside, Length to width ratio, diameter to height ratio, Carbon density of particles, bulk carbon density when stacked, % resins, etc, etc,</div><div class=""><br class=""></div><div class="">All the dots are connected forming a zig-zag around the circle. The stove has two circles; a maximum and a minimum. The biomass fuel has one as to conditions when prepared. Overlap and if the fuel falls within the stove requirements the fuel can be used. </div><div class=""><br class=""></div><div class="">Regards</div><div class=""><br class=""></div><div class="">Frank</div><div class=""><br class=""></div><div class=""><br class=""></div><div class=""><br class=""></div><div class=""><br class=""></div><div class=""><br class=""></div><div class=""><br class=""></div><div class=""><br class=""></div><div class=""><br class=""></div><div class=""><br class=""></div><div class=""><br class=""></div><div class=""><br class=""></div><div class=""><br class=""></div><br class=""><div class="">
