5. Adjust full load
When adjusting, the ratings data given by the boiler manufacturer and the capacity
graph of the burner should be observed [ch. 3.4.6].
Calculate gas throughput (operating volume V
B
Optimise setting pressure and/or gas butterfly valve setting [G] until gas
throughput (V
B
) has been reached.
Check combustion values
Determine combustion limit and set excess air via air damper setting [L/A], see
[ch. 7.5].
Determine gas throughput once more and adjust if necessary.
Re-set excess air.
The setting pressure must not be altered once this work has been completed.
6. Adjusting operating point P1
Press [-] key.
P
9
is saved.
Burner drives to operating point P
8
.
Check CO content of combustion and if necessary adjust combustion values via
gas butterfly valve setting [G].
Press [-] key.
Next operating point is initiated.
Repeat steps at each operating point until P
1
has been reached.
Operating point P
1
must lie within the capacity graph [ch. 3.4.6].
Determine gas throughput and if necessary adjust via gas butterfly valve setting
[G].
Check combustion values
Determine combustion limit and set excess air of approx. 20 … 25 % via air
damper setting [L/A].
