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;
