Easy loading.
In most cases the boiler
hopper needs loading only once a week –
this depends on the hopper capacity.
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

When purchasing pellets, ask
for conformity declaration
and certificate issued by an
accredited
laboratory
and
make sure the fuel meets the
requirements indicated in the
manual. If you purchase large
amount of pellets (bulk supply
for the entire heating season
for example), ask your supplier
to provde accurate and true
information about the storage
conditions.
- for sunflower pallets:
We recommend pallets with a diameter
6-8mm, density 500-650 kg/m^3 and
calorific value 4.-5.2 kWh/kg. Ash content
- no more than 3-4 % and moisture up to
11%.
The optimal density of the pallets, which
guarantees their quality is in the range
525-625 kg per cubic meter. The moisture
contained in the pellets must not exceed
11%. Make sure that you store your fuel
in a dry and airy place.
The optimal quantity of ash in the pallets
is <= 3%. Said quantity contributes to
how often you need to clean your burner.
-
for wood pallets:
We recommend to use pellet with size of
6 - 8mm. Density 600 - 750kg/m
3
heating
value 4.7 - 5.5 kWh/kg. Ash content – less
than 1% and moisture content up to 8%,
EN ISO 17225-2:2014.
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-A” burner.
