Requirements for pellet store Pellet store
The door's lock must be sealed against dust on the
inner side. In spite of a widely circulated construction
document, the door handle on the inner side may not
be removed. In an emergency, it must be possible to
open the door from the inside.
1 Seal between door and frame
2 Fire-resistant door
3 Z profile for boards
4 Boards
14.2.1 No cables/pipes in the pellet store
No water pipes or electrical cables in the pellet
store
In the pellet store, there should be no water pipes or
electrical cables. Water from a broken pipe would
cause the pellets to swell up. Uninsulated electrical
parts could ignite a dust explosion.
Existing cold water pipes that can only be removed
with unreasonable effort must be insulated against
condensation to ensure that the pellets cannot be
damaged by dripping condensation.
Pipes and cables in the path of pellets being injected,
especially those on the ceiling, must be shielded.
Ensure that the pellets are gently deflected by a
protective plate.

removed

2 Insulation for pipes
3 Protective plate
Only explosion-proof electrical installations
DANGER!
No electrical equipment such as switches, lights,
junction boxes, etc. may be present in the pellet
store.

Unavoidable installations must be airtight and
moisture-proof to protect against explosions, and
in the flight path of pellets they must be protected
against damage. Existing junction boxes that
cannot be installed elsewhere should at least be
filled in with foam to seal all exposed live parts.
14.2.2 Tilted floor
Inclination angle
The pellet store must have a floor inclined 40° to
ensure that all pellets in the store can be extracted.
Inclined floor design
The following materials may be used:
• 3-ply concrete formwork panels (27 mm thick)
• Unplaned wooden boards (25 mm thick) with a
smooth surface laminated with thin plastic
