Tab. 6-1: Useful cross section

With  the  useful  cross  section  of  the  storeroom,  the
storage  volume  and  the  storage  contents  can  be
calculated:

Storage volume (in m³) = useful cross section (m²)
x room length

Amount (in tonnes) = storage volume (m³) x 0.650

Filling nozzles

Installing the filling nozzles in the narrow side of
the pellet store

Two  nozzles  are  preferably  installed  in  the  narrower
outer  wall  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.

Return air nozzle

Label the filling nozzle and the suction nozzle so
that the pellet supplier recognises which nozzle

the pellets are blown into.
Opposite the middle filling 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.
