5.3. Adjustment of the thermal capacity of the burner
Adjustment of the thermal capacity of the burner is performed by simultaneous
adjustment of the position of the thermal capacity potentiometer (i.e. the fuel
flow rate) and the air flow rate, controlled by the flap of the burner’s air fan.
Information about the thermal capacity of the burner at different values of the
thermal capacity parameter P2 is shown in the following table.
P2
[number of LED blinking]
Thermal capacity of the unit
[kW]
1 5.0
2 8.0
3 11.0
4 14.0
5 18.0
6 21.0
7 25.0
8 29.0
9 32.0
Table 5.2. Thermal capacity of a system: pellet burner – heat consumer unit,
according to the value of thermal capacity parameter P2;
EXPLANATION: The above table gives information about the thermal capacity
of a system : pellet burner – heat consumer unit, assuming that the effective
efficiency is η = 0.89;
ATTENTION : In case of change of the fuel type (for example changing the
pellets category) an appropriate adjustment of the operating parameters
requirement could arise in order to achieve thermal capacity and high efficiency
of the system.
5.3.1. Decreasing thermal capacity of the burner
Thermal capacity of the burner is decreased by turning the position of the
potentiometer, positioned on the interface panel of the burner, in direction
to lower set-point – turn the potentiometer in direction anticlockwise,
which will result in decreased fuel consumption rate;
5.3.2. Increasing thermal capacity of the burner
Thermal capacity of the burner is increased by turning the position of the
potentiometer, positioned on the interface panel of the burner, in direction
to upper set-point – turn the potentiometer in direction clockwise, which
will result in increased fuel consumption rate;
