scale. (In our example, the amount
of pellets collected in the bag over a
15-minute period is
4320
grams
(900
sec)
. We then divide
4320
by
900
and get
4,8
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 25 model
:
we select
mode
Cycle
=
20 sec.
The heating value of
your fuel is
4,8kWh/kg
. (manufacturers
indicate the heating value of the fuel
on the packing – take it from there).
We then employ the following formula
to calculate the number of seconds for
setting the operation of the main auger
for these
20
sec.
:
t
FEED
= 25 000 / (4,8 x 180 x 4,8)
hence
t
FEED
= 6 sec.,
where
25,000
is the desired output of the
burner in Watts
(W)
,
4,8
is the heating value of the fuel in
kWh/kg,
180
is the number of burning cycles per
1 hour,
4,8
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
25,000 – 25kW
, we input the
desired kilowatts
(40 kW=40000 W, 70
kW=70000 W etc.).
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)
–
6
sec. (25kW)
Main combustion cycle (Cycle)
–
20
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)
–
3sec. (12,5kW; 6 х 50% = 3)
Main combustion cycle (Cycle)
–
20
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)
–
1,1
sec. (7,5 kW; 6 х 35% = 1,1)
Main combustion cycle (Cycle)
–
20
sec.
(recommended)
Fan output (Fan)
– adjust using gas
analyzer.
