2.6 - PELLET CHARACTERISTICS
The main feature of the ALLBIOMIX boiler is that of burning
natural fuel (pellets) obtained in an environmentally-friendly way
from wood industry waste (sawdust, powders). The sawdust
and powders coming from wood processing, after having been
appropriately cleaned and dried, are compacted at high pressure
to create pure wood cylinders: pellets.
The main features of the pellet are its low moisture content
(lower than 10%), its high density (> 600 kg/m3) as well as its
regularity and compactness providing this type of fuel a high
Net Calorific Value.
In order to provide ALLBIOMIX with a long lifespan, Unical
recommends the use of certified pellets.
The pellets used to feed the boiler must have high quality features
such as, for example, those determined by the standard EN
14961-2. The following are some of their fundamental data.
The pellets, as foreseen by current Italian
legislation governing commodity features of
fuels (DPCM 2.10.1995), must be produced
exclusively with untreated wood sawdust
without other materials added.
Storage and handling of pellets are important operations to be
performed with care:
- The fuel must be stored in a dry place which is not cold;
- Pellets must be moved in such a way to avoid excessive
crushing into fine powders.
Compliance with these two simple rules provides better
combustion efficiency and conserves the moving mechanical
parts of the appliance.
If ALLBIOMIX remains unlit for long periods
(more than seven days), the tank must be
emptied from residual fuel to keep it from
becoming excessively moist which could
cause the appliance to malfunction.
A high moisture content in the pellet can cause
it to break up into powder generating a greater
accumulation of residue in the brazier and a
blocking of the fuel feed system (screw).

2.7 - WOOD CHARACTERISTICS
Wood is formed mainly by cellulose and lignite. It
also contains other substances, such as resin (fir -
pine), tannin (oak - chestnut) and, obviously, a large
quantity of water.
Good quality woods are oak, ash, beech, maple and
fruit trees, except cherry; medium quality wood is:
chestnut and birch; sufficient quality wood: lime tree,
poplar and willow. Resinous trees are, normally,
second-rate quality fuels.
Wood is therefore an extremely heterogeneous
fuel, due to different essences (beech, oak, fruit,
resinous), different moisture content, and due to
different shapes and dimensions.
Boiler operation will inevitably be effected by all
these factors. Especially by the log dimensions, the
moisture content and the way wood is loaded in the
boiler.
WOOD MOISTURE
The calorific value of the different types of wood
depends on their moisture content, as illustrated in
the table. Boiler output and autonomy will diminish as
the moisture increases.The table provides the power
reduction factor based on the moisture of the wood
being used.The heat output of the ALLBIOMIX boiler
is calculated for wood with a 17% moisture content.
As an example, wood which has been dried for
2 years in a sheltered area has a 25% moisture
content.
Example:
moisture of the wood being used = 30%
output = nominal output x 0.79

DIMENSIONS
The dimensions, together with the moisture content,
contribute to determine the boiler’s output. Small
pieces (with a length, however, conforming to indi-
cations indicated hereby) are more easily flammable
and therefore have the tendency to increase the
boiler’s output and therefore to reduce its auton-
omy. Moreover, they fall with greater facility, in the
lower chamber, reducing the risk of the formation of
“bridges”. The so-called “bridge” is an empty space
in the firewood storage compartment, where unburnt
wood logs remain. In this case the bed of embers
is not fed with continuity and the refractory burner’s
slot is uncovered. In these conditions, preferential
air ducts are created with a very small flame due
to an excess of air.
USEFUL TIPS AND WHAT TO AVOID
- Logs which are too long do not fall down properly and can
cause "bridges".
- Logs which are too short cause irregular air ducts, with con-
sequent reduction in output and efficiency.
- If the quality of the wood causes "bridges", it could become
necessary to load logs cut in half so that the total length “L”
is as indicated in the previous paragraph.
To avoid the formation of "bridges", it is unadvisable to place
logs against the side walls of the wood storage compartment.
(see fig. 3).
- Always open the upper door slowly, in order to avoid blow-
backs and smoke formation.
- During normal boiler operation, it is absolutely forbidden to
open the lower combustion chamber door.
