Pellet burner GP xx sc 22
After the starting blowing by the fan, the burner feeds primary fuel doze and starts the
process of ignition. The display panel shows
”IGNITION 1”
– first attempt for ignition, which
has to be completed within a period of time, defined in the controller’s software.
The burner’s controller is factory programmed with the optimal operation mode adjustments.
Discrete number of heating output levels are set, through which the burner operates. The
last, maximum level of the heating output is adjusted in a way that provides higher heating
output than the burner’s nominal output – this mode is designated for situations when the
used fuel caloricity is lower than the normal or when the heat energy consumption exceeds
the burner’s nominal output.
Only short time for operation (totally 10 hours for entire heating season) of the burner in
modes exceeding its nominal heating output are recommended, because such modes lead to
increased heat-loading of the burner’s construction and to decreased life resource.
The practice shows that the factory adjusted parameters of the burner do not need additional
corrections, even if different fuel types are used.
The manufacture company reserves its rights to change the settings of the
appliance, without obligation to inform the end users.
The values of the parameters, which define the heating output of the pellet burner from
series „GP xx sc”, are determined under the following conditions:
The utilized wood pellets are with diameter Ø 6-8mm, quality classes A1, A2 and B,
according to standard EN ISO 17225-2:2014 or category: A, AB, B, BC and C (see
Tables 3.3 and 3.4);
The tilting angle between the longitudinal axis of the transport auger and the
horizontal plane is 45
o
;
The ash content (mineral, inflammable mass) does not change significantly the fuel’s
calorific value, but requires special construction of the burner in order to achieve
efficient and economic burning process. Therefore the applicability and efficiency of a
certain fuel have to be tested and after positive results such fuel should be utilized by
the burner;
The manufacture company reserves its right to change the default parameters, which
manage the burner’s operation, without obligation to inform its customers;
Table 6.1 presents the factory settings of the heating output levels, through which the
burner achieves optimal operation performance;
The presented heating output levels define the heating output and the operation
modes of the burner;
The primary adjustment of the burner at the customer’s site is performed by trained
servicing technician, after that the user is not required to perform more changes;
The next texts below describe how to define the fuel consumption and to calculate the
burner’s heating output:
Switch the burner ON;
Dismount the flexible pipe, that connects the auger and the main module, from the
burner and direct the free end to a container (for example plastic bag or other), so the
dropped pellets by the auger gather inside;
Then an authorized technician chooses the menu
