Adjustable Parameters - Flue Gas
Maximum heating up time,
during which HEATING mode
must be reached 10 m
After this time has elapsed, after the start of heating, and the
minimum difference between flue gas and boiler temperature has not
been reached, the Boiler Control System switches to “Off” mode.
Minimum flue gas
temperature 120°C
Min. target value for the flue gas temperature. Lowest load point for
continuous operation.
Maximum flue gas
temperature 250°C
Max. target value for the flue gas temperature. Highest load point for
sufficiently good degree of efficiency.
Start increase of flue gas
temperature 20°C
Value, by which the flue gas target temperature is increased when
heating up.
Minimum difference between flue
gas temperature and boiler 15°C
Starting condition for “Heating” mode.
Flue gas temperature, below
which boiler switches to
SHUTDOWN status 80°C
If the flue gas temperature is below this value for the duration of the
maximum heating up time, the Boiler Control System switches to
“Off” mode.
Adjustable Parameters - Air settings
Adjusting the minimum speed of the Induced Draft Fan
Base point for setting the Induced Draft Fan characteristic line
End point for setting the Induced Draft Fan characteristic line
Minimum opening of the primary air damper
In heating minimum
secondary air from 10%
Minimum opening of secondary air damper in “Heating” mode
Primary air during slumber 20%
Opening of the primary air damper in “Slumber” mode
Safety time for checking
for air leaks 115m*
If the secondary air is 0% and the flue gas temperature is over
100°C this time starts to run. If it is certain that within this time the
two values do not change, the error note “Boiler has air leak” will be
displayed.
