combustion process, the optimal combustion process should be stable, no
unburned char particles should be observed as well. The practice shows,
that the factory set values do not need any onsite adjustment, regardless
the difference of the fuels utilized;
The producer reserves the right to change the specification and/or the default
values of the operating parameters of the unit without prior notice;
NOTES:
The default values of the operating parameters of the pellet burner of
series “GP” are derived at the following conditions:
o
The fuel is wood pellets, with diameter d=8 mm,
A
category (see
table of wood pellets categories);
o
The axial inclination of the fuel transport auger (the angle between
the auger axis and horizontal plane) is 45
o
;
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;
Tables 5.1. and 5.2. contain 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;
