Beercontroloffuelquanty. The small
size of the pellets allows for precise fuel
feeding. On the other hand, the supply
of air for reaching opmal combuson
eciency is easier to adjust since the
fuel quanty in the combuson chamber
remains constant and predictable.
Fuel eciency. High combuson
eciency is also determined by
consistently low moister content of
pellets (consistently under 10% as
opposed to 20% to 60% moisture content
of the logs). Low moisture content,
controlled fuel porons and precise air
seng means high combuson eciency
and very low carbon oxides in the ue
gases.
