5 Operating the system
5.1 General information
The steeper the angle (FBR maximum 15° / TGR maximum 10°) at which a rotary
agitator is fitted, the more likely that fuel will remain behind when the bunker empties.
When operating with pellets it is particularly important to note:
▪ Fit as flat as possible (FBR maximum 5° / TGR maximum 3°), ideally horizontal
▪ Fuel may remain in the store due to its high propensity to trickle
▪ The boiler must be turned off at least two hours before fuel is blown in
5.2 Initial startup
NOTICE
Efficient operation can only be guaranteed if the system is set by specialist staff
and the default factory settings are observed.
Therefore:
❒ Initial startup should be carried out with an installer approved by Fröling
Heizkessel- und Behälterbau GesmbH or with Froling customer services
Before commissioning or before the first filling, carry out the following checks:
❒ Check the direction of rotation of the screw
❒ Check the direction of rotation of the rotary agitator arms
❒ Check that the safety limit switch on the gravity shaft is working
❒ Check that the motor overload for the drive motor is working
❒ Check the connection of the sprinkler device
❒ Check there is a shear plate in the area of the wall penetration
When the check is finished:
❒ Fill the store with fuel
