The optimal density of the pellets which
guarantees their quality is 605-700 kg per
cubic meter.
Pellet moisture content must not exceed
10%. Make sure you store your fuel in a
dry and well-ventilated place.

The optimal pellet ash content is ≤ 1%.
This also provides for less frequent
cleaning intervals for the burner.
The table below contains the parameters
which we recommend that you take into
consideration when choosing fuel for your
Pell burner.
1)
not more than 1% of the pellets may be longer than 40 mm, max. length 45 mm;
2)
dry weight;
3)
particles <3.15 mm, particulate matter, before handing over the goods;
4)
measurements with Ligno-Tester limit value ≥ 97,7% by weight.
