1.1 Functional description
TGR torsion arm agitator: FBR spring blade agitator:
A Rotary agitator geared motor F Rotary agitator mitre gear
B Rotary agitator duct with drive shaft G Discharge screw geared motor
C Rotary agitator plate H Gravity shaft
D Articulated arms with torsion springs
(TGR)
I Discharge screw closed trough
E Spring piles (FBR) J Discharge screw open trough
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.

Information about the fuel store
NOTICE! The fuel store plate provided must be affixed in a conspicuous place in the
access area of the store
When FILLING the fuel store, observe the system DOCUMENTATION.
The filling procedures may vary depending on the discharge system, type of fuel and
fill level of the fuel store. Only use fuels permitted according to the boiler’s operating
instructions.
SWITCH OFF the HEATING AND FEED SYSTEM before ENTERING the fuel store.
Risk of injury due to moving parts and automatic startup. Shut off the feeder unit
before entering the fuel store and secure it so that it cannot be switched on again.
There is a further risk of injury from the uncontrolled rotation of spring-loaded
components. These must be secured during work.
There is a risk of carbon monoxide poisoning in the pellet stores. Adequately ventilate
the store before entering (at least 15 mins.). Only enter the store under the
supervision of a second person. While in the store, keep the door open and use a dust
mask! There is a risk of collapse and being buried alive as a result of cavity formation
in the store. Therefore, do not enter the fuel area!
Slick surfaces in the fuel store present a slipping hazard and fuel supply points
present a risk of falling.
As a rule, personal protective equipment (work clothing, protective gloves, sturdy
shoes) should be worn when working in the store and on the conveyor.
Unauthorized access prohibited! Keep children away! Design the fuel store in such a
way that it is safe to access and keep it locked. Keep the key in a safe place. No fire,
open flames or smoking! Protect the fuel from moisture.
Affix this notice in a conspicuous place in the access area of the fuel store.
