Better control of fuel quantity.
The small
size of the pellets allows for precise fuel
feeding. On the other hand, the supply
of air for reaching optimal combustion
efficiency is easier to adjust since the
fuel quantity in the combustion chamber
remains constant and predictable.
Fuel efficiency.
High combustion
efficiency 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 portions and precise air
setting means high combustion efficiency
and very low carbon oxides in the flue
gases.
