Arrangement and installation of the pellet burner’s modules
The main unit
of the burner should be installed in horizontal position on a heat
energy consumer appliance. According to the type of the appliance, an expert should
prepare technical evaluation of the project for installation of the burner, as well as
local arrangement of the units in order to ensure efficient and reliable system
operation and easy access for cleaning and maintenance purposes. The main unit of
the burner should be attached to the heat energy consumer appliance. The insulation
gasket should be placed between the main unit and the heat energy consumer;
Fuel transport auger
is positioned in a close region of the burner of series “GP”, in
order to allow its easy connection with fuel delivery pipe of the main unit by the
applied transparent flexible hose. The auger should be positioned at 45
o
– the angle
between the axis of the auger and the horizontal plane, in order to provide optimal
operating conditions for the electric motor and efficient combustion process in the
combustion chamber of the main unit. The lower section of the auger should be
positioned in the fuel bunker and appropriate measures should be taken in order to
prevent fuel discharge through gaps between the auger’s pipe and the wall of the
bunker. Additionally the lower section of the transport auger should be positioned in
the lowest part of the hoper in order to ensure reliable fuel charging of the auger’s pipe
entrance. The final position of the transport auger should be fixed. The fuel transport
auger and the hoper should properly be arranged in order to ensure safe operation of
the units and easy access and maintenance. The installation of the flexible hose should
be considered as well – it could be bended and eventually its length could be
decreased if necessary;
In order to achieve optimal operation of the fuel transport auger, it is
recommended
to install a pellet hopper of series “BP” – produced by pellet burner producer
company as well.
ATTENTION:
any change of the position (i.e. angle between the auger’s axis and the
horizontal plane) practically influences/changes the fuel flow rate and the thermal
capacity of the burner as follows:
o
decrease
of the angle between the axis of the transport auger and horizontal
plane leads to
increased
fuel flow rate and respectively higher thermal
capacity of the burner;
o
increase
of the angle between the axis of the transport auger and horizontal
plane leads to
decreased
fuel flow rate and respectively lower thermal
capacity of the burner;
Flexible hose
should be installed – it connects the exit pipe of the fuel transport auger
and the fuel delivery pipe of the main unit. The flexible hose should be straight (no
visible hose slacking is allowed as such regions could accumulate dust and small fuel
particles) and finally its ends should be tightened to the pipes by applied adjustable
braces;
