Fuel store discharge with the bottom agitator in a lightweight design,
especially for smaller volumes and/or lower boiler outputs. The flexible
agitator discharge is suitable for round, square and rectangular
spaces.
The fuel is conveyed via a bottom agitator with 2 leaf spring arms,
which fill a screw conveyor channel set into the floor (or intermediate
floor). If the fuel store is full, the leaf spring arms move to the top-hat
disk. The system is driven by a geared screw conveyor motor to the
discharge screw conveyor and via an angular gear to the agitator.
