Flue gas
Minimum flue gas temperature
Specifies the minimum flue gas temperature setpoint in °C.
NOTICE! When using the TI wood chip boiler, the lower
range of the output increase is calculated in conjunction
with the predefined flue gas control band.
Maximum flue gas temperature
Highest operation point of flue gas temperature for
continuous operation.
Maximum flue gas temperature
Specifies the maximum flue gas temperature setpoint in
°C.
NOTICE! When using the TI wood chip boiler, the upper
range of the output decrease is calculated in conjunction
with the predefined flue gas control band.
Boiler output at flue gas temperature of 20°C
Lower point of the start ramp of boiler controller at system
startup.
100% boiler output from a flue gas temperature of
Upper point of the start ramp of boiler controller. If the flue
gas temperature reaches the value set here, the fuel
output should reach 100%.
Minimum difference between flue gas temperature and
boiler temperature in HEATING
As a condition for the “
Heating
” operating status, the
difference between the current flue gas temperature and
the current boiler temperature must at least exceed the
value set here.
Flue gas - Flue gas difference for start process
When the boiler controller changes to “
Pre-heating
”
status the current value of the flue gas temperature is
stored. When the flue gas temperature rises by the value
set here during “
Pre-heating
” or “
Ignition
” status, the
boiler controller switches to “
Heating
” status.
Safety time
If the condition “
Minimum difference between flue
gas and boiler temperature in HEATING
” is not
fulfilled for the set duration, the message “Safety time
expired, flue gas temperature too low for too long” appears
on the display.
Flue gas temperature, below which boiler switches to
SHUTDOWN status
If the flue gas temperature is below this value for the
duration of the
“Safety time”
, the boiler switches off.
Boiler flue gas difference for fire out
If the current boiler temperature plus the set value is
greater than the current flue gas temperature, the boiler
switches off.
Control band for flue gas temperature
Defines the control band in °C before reaching the
minimum or maximum flue gas temperature.
Ignition power at flue gas temp.
Specifies the flue gas temperature that must be reached,
so that power can be increased. Below this temperature
the boiler is limited to the ignition power. Above this
temperature the maximum possible power is calculated
from the control curve (“
ignition power at flue
gas temperature
” parameter -> "
100% boiler
power at flue gas temperature of
” parameter).
This should prevent the cold fire clay from heating up too
quickly.
