24. Boiler room with a large built-in pellet storage
A boiler plant with a built-in pel-
let storage with the volume of
e.g. 5 m
3
in which you can store
3250 kg of pellets. For this purpose
a 2 m (2.5 m) conveyor is used. For
easy access to the storage a segmen-
ted opening is produced that can
be adapted to the pellet level in the
storage and enables cleaning of the
storage from dust and dirt once a
year. In the top part of the storage
there are two openings for replenis-
hment of pellets from a cistern that
have different sizes with regard to
pellet suppliers.
For optimum collapsing of the pel-
let heap the optimum angle of the
inner walls in the storage must be
at least 45°. All the walls are incli-
ned to the lowest point of the stora-
ge from which the worm conveyor
draws pellets.
CAUTION - If pellets are drawn to the storage in the boiler plant directly from the cistern,
several principles must be observed that prevent their crushing during pneumatic transport.
First of all you must make sure that they do not hit the hard wall of the storage, but a screen
that is suspended in the centre of the storage from the ceiling. is way you will ensure even
filling of the storage and prevent crushing into small pellets and dust. Ask the pellet suppliers
about further possibilities and conditions of pellet drawing.
