When planning the pellet store you should keep in mind that you cannot use the same
feeding system for a store designed for a day’s or a week’s supply as for a store desig-
ned for bulk deliveries. A common way is to start with a small and simple pellet store
which is a quick and simple solution. It demands a bit of handling however, both when
you pick up the pellets from your supplier and when you fi ll them into your store. For
this kind of store, pellets can be acquired in small sacks (normally between 6-20 kg) or
large sacks (normally between 500-1000 kg).
Th
e very best solution for a convenient and simple handling of pellets however is
to install a pellet store designed to accommodate pellets delivered by bulk tanker. Th
is
delivery method will demand a store of some 6 m
3
to accommodate 3 tons which is the
normal volume at bulk deliveries.
Th
e pellet store should be designed to eliminate the risk of contamination and
moisture penetration. Take special care to avoid damp penetration through the walls
and fl oor. It is also important that pellets are not exposed to direct contact with water
in the form of rain or condensation. Pellets do not however absorb moisture from
surrounding moist air and can therefore be stored outdoors as long as they are under
cover. Th
e fuel store should be planned according to your estimated consumption so
that refi lling and handling takes place at convenient intervals.
