Figure 5.5. The display indicates information about the operating mode of the burner
–
in the example the control module is in fuel ignition process mode.
COMMENTS:
●
After the initial ash residue air blowing by the fan, the control module of the burner
starts to supply the initial amount of fuel and starts the process of fuel ignition. The
display indicates the operating mode „
IGNITION 1”
– this is the first attempt
(indicated by number 1) for fuel ignition, which is realized for a duration, defined in
the operating software;
●
The control module of the burner is preprogrammed in the producer’s factory with
factory default values for the operating parameters, considered to be optimal for most
of the common cases of burner’s operation. The control module operates at discreet
thermal capacity stages, which are adjusted to predefined thermal capacities of the
burner. The maximal thermal capacity stage, however, is adjusted to allow higher
thermal capacity of the burner, than the nominal one – this stage is dedicated for
cases of low quality fuel (i.e. with lower than required net calorific value of the fuel)
or in case the heat demand exceeds the thermal capacity of the system: pellet burner –
heat consumer (in most of the cases hot water boiler). It is recommended to operate at
the highest thermal capacity stage no more than 10 hours for the entire heating
season, in order to sustain high reliability of the pellet burner, as high thermal
capacity operating modes result in increased thermal loads of the modules of the
burner and decrease its life span;
●
The practice shows, that the factory set values for the operating parameters does not
require additional adjustment, even if the fuel has been changed during the
exploitation period of the burner;
The producer reserves the right to change the values of the operating parameters of the pellet
burner control module without prior notice;
NOTES :
The values of the operating parameters, which define the thermal capacity of the
burner are determined by the following conditions:
o
The utilized fuel is : wood pellets with diameter d=8 mm , class ENplis-A1
(see the fuel properties table);
