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.
The feed output can be variably adjusted regardless of the discharge screw thanks to
the separate drive of the rotary agitator.
