Speed of flue gas blower on the Vitoflex 300-RF ECO.
The speed of the flue gas exhaust blower can be
adjusted between 0 and 60 Hz in 14 levels.
Only display if:
oil/bas burner available (Service Vitoflex 300-RF)
Is a minimum threshold of the system target temperature
necessary (e.g. with customer-side heat distribution this
parameter must be set to Yes)?
It is possible to adjust the minimum target system
temperature in the parameters menu
Is an oil/gas burner fitted to the Vitoflex 300-RF ECO
Is a flue gas recirculation system installed?
(Flue gas recirculation system YES: the primary air
vent is closed below 30 Hz depending on the current
speed of the flue gas blower in order to feed more
recirculated flue gas to the combustion in lower partial
load operation)
Speed of the output controller:
Rotational speed increase or decrease
Speed of the material volume controller
In-feed auger duty cycle
Vitoflex 300-RF maximum supply temperature:
when this temperature is exceeded the system switches
from load operation to auger idle run.
Time delay on exceeding the maximum supply
temperature empty auger.
On loader idle run, the in-feed auger is halted if the
residual oxygen content exceeds this limit value
IMPORTANT: Noise development from the empty in-feed
auger!
When this limit value is exceeded the in-feed auger is run
idle in automatic mode
( In-feed auger warm)
At which light barrier should the ember monitoring
system initiate control:
Large ember bed: both light barriers must be broken.
Small ember bed: only light barrier 1 (closer to the in-
feed and /or lower) must be broken
