The inclination of the axis of the fuel transport auger measured on basis of the
horizontal plane is 45
o
;
The content of ash (mineral incombustible matter) in the fuel does not change
significantly the net calorific value, but requires special design of the pellet burner, in
order to achieve reliable and efficient combustion process. That’s why the
applicability and the effective utilization of certain fuel should be verified and after
approval should be utilized in the pellet burner;
The producer reserves the right to change the values of the operating parameters,
which are controlling the pellet burner, without prior notice;
In Table 5.1. are described the factory default values of the thermal capacity stages of
the burner, used to obtain optimal operating conditions for the pellet burner;
The tabled stages for the thermal capacity of the burner define its thermal capacity as
well as the operating modes of the unit;
The initial adjustment of the burner is realized by authorized trained service
technician, after that no additional adjustment by the end user is required;
The following text describes the procedure for determining the fuel supply rate and
determining the thermal capacity of the pellet burner:
o
Power on the burner;
o
Detach the fuel delivery flexible pipe from the fuel supply pipe of the pellet
burner’s main module and put the end orifice of the flexible pipe into a container
(for example a PVC bag, a vessel or any appropriate container) in order to
collect all the fuel particles, transported by the auger;
o
Performed by authorized technician only, select the „Advance menu” and
activate the operating parameter „Stoker adj”.
NOTE:
the access to this
advanced menu is restricted by password and is accessible by authorized
technician only
;
o
Then the auger will operate continuously for a predefined period of 6 minutes.
The collected in the container fuel quantity should be weighted and introduced
in the operating parameter of the control module, following the onscreen
information. After the initial fuel flow rate measurement, the nominal operation
of the burner should be activated. In case the net calorific value of the utilized
fuel is known, then it could be introduced in the operating parameters of the
control module as well. The factory default value for the net calorific value of
the wood pellets is 4,8 kWh/kg. After the fuel specification data has been
introduced, these data changes should be saved, by appropriate choice of menu
item, indicated on the control module’s display – follow the onscreen
instructions to proceed, utilizing the appropriate buttons indicated below the
text. After these adjustments, the pellet burner have defined and controlled
thermal capacity, complying the appliance producer specifications;
The producer reserves the right to make changes if the factory default values of the operating
parameters without prior notice end users or service technicians.
5.2.7.
Adjustment of the pellet burner, according to the heat consumption rate
It is highly recommended to adjust the operating thermal capacity of the pellet burner
of series “GP” as well as the heat consumer unit, in order to achieve high efficiency and
reliable operation of the system.
The adjustment process consists of individual adjustment
of the operating thermal capacity stage of the burner, as shown on Table 5.1.;
At the thermal capacity operating stage adjustment of the pellet burner of series “GP”
the adjustment of the air flow rate, supplied by the air fan, is not required, as the operating
mode of the fan is controlled by the burner’s control module unit.

Nominal operating mode of the burner
