Filling nozzles Pellet store
The table below can be used to determine the useful
cross section of a store in m² under the following
conditions:
•
40° tilted floor
• Free space above 0.40 m
• Free space for conveyor screw 0.13 m
Tab. 13-1: Useful cross section of store in m²
With the useful cross section of the store, its volume
and the amount of pellets can be calculated:
•
Store volume (in m³) = useful cross section x room
length
• Amount (in tons) = store volume (m³) x 0.65
13.4 Filling nozzles
Installing the filling nozzles in the short side of the
pellet store
Two nozzles are installed in the shorter wall (prefera-
bly) of the pellet store, One for blowing in the pellets
(filling nozzle) in the middle and the other for back air
(back air nozzle) to the side.
Fig. 13-1: Filling nozzles on the short side
1 Filling nozzle
2 Conveyor screw
3 Impact protection mat
4 Back air nozzle
Opposite the central nozzle, an impact protection mat
is installed 500 mm from the wall to prevent damage to
both pellets and the plasterwork on the wall.
The filling nozzles must be installed 200 mm below the
ceiling to keep the pellets from scraping on the ceiling
during injection.
Only in exceptional cases, when no short wall of
the pellet store is accessible from the outside,
can the filling nozzles be positioned on the longer wall.
