the flexible pipe is attached.
Filling of the pellet auger is necessary
when the fuel in the hopper has been
depleted or when fuel has been changed.
Once you have ensured that the pellet
auger has been filled, take an empty
plastic bag and fixed it securely on the
pellet auger, at the place of the flexible
pipe. Reconnect the auger to the power
socket and measure the amount of
pellets collected in the bag over a period
of 15 minutes using scales/weighing
scale. (In our example, the amount
of pellets collected in the bag over a
15-minute period is
50400
grams
(900
sec)
. We then divide
50400
by
900
and
get
56.6
grams of pellets per 1 second.
Repeat the measurement in order to
obtain conclusive results .
10.2. Burner output adjustment.
In the burner output settings menu you
can adjust the running time of the main
auger (
Feed
); main running interval
(
Cycle
) and fan output (
Fan
).
Example for Pell 300 Mega
: select mode
Cycle
=
10 sec.
The heating value of
your fuel is
4.8kWh/kg
. (manufacturers
indicate fuel heating value on the
package – see the fuel package). Then
employ following formula to calculate
the number of seconds for setting the
operation of the main auger for these
10
sec
:
t
FEED
= 300 000 / (4,8 x 360 x 56,6)
hence
t
FEED
= 3 sec.,
where
300 000
is the desired output of
the burner in Watts
(W)
,
56,6
is the heating value of the fuel in
kWh/kg,
360
is the number of burning cycles per
1 hour,
56,6
is the amount of pellets in grams
fed by the auger per
1
second. This way
the output mode can be changed and
instead the number
300 000 – 300kW
,
we input the desired kilowatts
(500 kW
= 500 000W).
Take also note of the fuel heating value
which would change the value for the
feed and the burner output.
Using the above procedure, you can set
any of the three output modes of the
burner.
Mode
: Maximum output
mode
– It is indicated by three flames.
Pellet auger running time (Feed)
–
3 sec.
(300 kW)
Main combustion cycle (Cycle)
–
10 sec.
(recommended)
Fan output (Fan)
- adjust using gas
analyzer.
Mode
:
Medium output mode
– It is indicated by two flames.
We recommend to set value at
50%
of
the main mode.
Pellet auger running time (Feed)
–
1.5sec. (150 kW; 4 х 50% = 2)
Main combustion cycle (Cycle)
–
10 sec.
(recommended)
Fan output (Fan)
- adjust using gas
analyzer.
Mode
: Low output mode
– It is
indicated by one flame.
We recommend to set value at
35%
(0,35)
of the main mode.
Pellet auger running time (Feed)
–
0,5
sec. (50 kW; 4 х 35% = 0,5)
Main combustion cycle (Cycle)
–
10 sec.
(recommended)
Fan output (Fan)
– adjust using gas
analyzer.
