Pellet container
The burner, the auger and the pellet container are a common system. The size and the location of
the pellet container depends on the needs and possibilities of the specific boiler room. While
choosing the pellet container you must keep in mind that:
•
If the pellet container is in the same room as the boiler, then the size of the pellet container
must not exceed 500 liters (approx. 350kg).
•
The container must be made of fireproof materials.
•
The container must be positioned in a way that the raising angle of the feeding auger does
not exceed 45°.
It is advisable to use a container that can be closed with a cover.
External auger
A feeding auger transports pellets from the pellet container to the burner. The burner controls the
work of the auger. The auger is connected to the burner with a special hose. The hose is made of
melting material that acts as a safety measure against back-burning. The uppon side of auger (with
motor) must be fixed (with delivered chain) to a storage or to some other object nearby.
Figure 7 shows correct position for external auger. As the hose is a safety device, it must be placed
strictly as described below. The vertical distance between auger outlet and burner inlet must be in
range of 40..70cm and horizontal displacement 10..20cm (typical auger angle 30
o
..45
o
). External
auger cannot be installed in position with angle greater than 45
o
. The hose must be in angle of 50
o
or
more to ensure free falling of the fuel.
