Scorch phase
During the scorch phase the boiler control tries to
achieve an even fire bed. The length of the scorch
phase can be set in the fuel value settings (only
available in the service area). Pay attention to the
higher oxygen content at the combustion. During
the scorch phase the boiler control tries to achieve
an even fire bed.
Start up phase
During the start up phase the boiler operates at
nominal heat output. If the boiler set temperature
is reached, the boiler will switch to the regulation
phase.
Regulation phase
During the regulation phase the boiler is
modulated between nominal load and partial load.
If boiler oversupplies heat, i.e. if the boiler target
temperature + control hysteresis gets exceeded,
the boiler will switch to the operating condition
„ready”.
Burn out phase
If the boiler will be switched off the remaining
quantity of residual fuel will burn independently.
Pay attention to the burn out phase time setup, if
chosen too short, fuel will not be burned
accordingly.
Burner cleaning
During the burner cleaning phase ash gets
removed off the grate. The boiler switches to the
burn out phase and remaining fuel gets burned
out.
Afterwards the grate gets cleaned and the boiler s
witches to normal operation. Afterwards the grate
gets cleaned and the boiler switches to normal
operation. The burner cleaning interval is
calculated by the feeding screw operating time.
This is set up with the parameter
“ash discharge
interval” in the service area. So if the grate should
cleaning frequently you have to reduce the
parameter.
Heat exchanger cleaning
The Heat exchanger gets cleaned automatically.
The cleaning interval and duration is set up in the
service ar
ea with the parameter “heat exchanger
cleaning interval“ respectively „heat exchanger
cleaning duration“.
Boiler output control
The output control is controlled within the boiler
target temperature and the control end phase.
The control end phase is the boiler target
temperature + control hysteresis. If the regulation
end is reached, the boiler will switch to the burn
out phase.
Flue gas temperature control
If the maximum flue gas temperature is exceeded,
the boiler output will be reduced. If the actual flue
gas temperature is lower than the maximum flue
gas temperature, the boiler will switch to normal
output control.
Flame monitoring (burning chamber
temperature)
If the burning chamber temperature fluctuates
greatly during operation, the boiler will switch off.
Freezing protection
If the freezing protection operates, the back flow
bypass pump will switch on only if the boiler is in
operating mode “HEATING OFF” or “BURNER
STOP”. Otherwise (freezing protection disabled)
the boiler will start up and heat up to minimum
boiler temperature.
Lambda control
The amount of material and the rotation speed of
the ID-fan are controlled by the lambda control.
The control is able to detect marginal deviations of
the fuel quality and induces a combustion
improvement.
