The axial inclination of the fuel transport auger (the angle between
the auger axis and horizontal plane) is 45

;
•
The ash content (mineral, incombustible content in the fuel) does not
influence significantly the gross calorific value of the fuel, but requires
specialized design of the burner in order to achieve optimal and efficient
combustion process. Following this, one should test the applicability of a
fuel for combustion process in the current design of the burner and if
positive result is achieved to be massively utilized as fuel material.
However, many aspects of the unit operation should be considered;
•
The producer preserves its right to change any factory preset value of the
operating parameters of the burner, without a without prior notice;
•
Table 5.1. contains values of the operating parameters of the control board
and the default values are indicated;
•
The above shown values of operating parameter P2 define the thermal
capacity of the burner;
•
Adjustment of the burner’s thermal capacity could be achieved by
detecting the fuel flow rate at nominal operating mode – the amount of
fuel transported by the auger for certain period of time at nominal
operating mode, considering the gross calorific value of the fuel and the
overall efficiency of the system: burner-heat energy consumer unit.
•
An approach to determine the fuel flow rate is as follows :
o
The flexible hose, which connects the fuel transport auger and the
main unit of the burner should be disconnected at the main unit’s
side and is directed to a fuel container (for example a plastic bag or
somewhat appropriate) and the transported fuel will be accumulated
in this container;
o
Switch ON the burner and set START signal (by the control unit of
the energy consumer) ON as well;
o
Unplug the photosensor by drawing until it is out of the sensor’s
handler and the control board of the burner will analyze this mode
as nominal operation one (i.e. presence of combustion process);
o
In this mode the control board will power the transport auger’s
electric motor and fuel will be transported regularly. The fuel,
which goes off the exhaust side of the flexible hose should be
collected with no scattering in a container for a measured period of
time. For example: the measuring period is 15 minutes (which is ¼
of an hour) and the container’s accumulated fuel mass is 1.0 kg.
The calculation shows that the fuel flow rate is 4 kg/h (practically
the fuel flow rate is determined by dividing the accumulated fuel
