The Froling discharge system “Spring blade agitator (FBR)“ consists of:

8
9
12
710
11
1Spring piles
2Rotary agitator head
3Intermediate plate for connecting the raised floor to the rotary agitator head
4Mitre gear
5Trough channel, open
6Discharge screw
7Cover plate for wood chips or pellets
8Raising plate for fuel store without raised floor
9Transfer channel from open to closed trough channel
10 Trough channel, closed
11 Top part of gravity shaft with gravity shaft cover and water sprinkler system
12 Geared motor
When the store is full, the rotary agitator arms are positioned at the rotary agitator plate,
reducing resistance during system operation due to the smaller diameter.
If fuel is requested using the boiler controller, the system starts and the material is
loosened by the pre-tensioned rotary agitator arms, and fed to the trough of the discharge
screw. The discharge screw feeds the material to the transfer position, where it falls
through the burn back protection system (burn back flap/rotary valve) into the stoker
screw of the boiler that is positioned below or into another feed screw.
