4 Inspection
opening
Maintenance opening with class EI
2
90-C fire resistance rating (e.g. chimney
door) immediately over the hole in the wall for easy clearance of any
blockages from oversized material around the shear edge of the discharge
screw. The inspection opening must be designed in such a way that it can
only be opened with a tool. The operator must highlight residual risks at the
inspection opening.
5 Side wall
protection
If the structure of the store means that the arms come into contact with the
wall (rectangular room), we recommend that you fit an approx. 300 mm
high covering made of sheet metal or hardwood to the wall of the store.
This prevents pieces of the wall and plaster from breaking off and blocking
the discharge system.
6 Raised
floor
This prevents material from remaining below the rotary agitator arms. This
material would decay, and this could affect the heating value. For this
reason, we recommend that the customer installs a raised floor. The
construction should be dimensioned so that the raised floor is not deformed
under the static load of the fuel. The raised floor must also be self-
supporting, and it should not be supported by the screw channel.
4.2.1 Information about setup
❒ The rotary agitator duct should be fitted in the centre of the store at an angle of
90° to the wall.
❒ The discharge screw must be positioned so that the shear edge (transition from
open to closed trough) is at least 200 mm away from the wall.
Correct position of the discharge screw
NOTICE
Malfunctioning of discharge system because discharge screw is in incorrect
position
Positioning the open trough of the discharge screw next to the rotary agitator
plate may cause bridge formation and malfunctioning in the discharge when the
bunker is full.
Therefore:
❒ Position all, or at least half, of the open trough of the discharge screw under
the rotary agitator plate
