Conversion of vol.% CO
2
into vol.% O
2
for
burner setting
Depending on the nominal CO
2 max
in vol. – % of the distributed gas, the
named CO
2
default value can be converted into an O
2
default value
according to the following formula:
F. 1
Formula for calculating the O
2
value
[O
2
] Default value of O
2
in vol. – %
[CO
2
] Default value of CO
2
in vol. – %
[CO
2max
] Nominal value of CO
2max
for the distributed gas in vol. – %
(with LPG: CO
2max
13,75%)
Calculation example:
Default value for CO
2
= 9.2 vol. – %
Nominal value for CO
2max
= 12.0 vol. – %
F. 2
Example of O

value calculation
[O

] O
2
in vol. – %
[9,2] Default value of CO
2
in vol. – %
[12] Nominal value of CO
2max
for the distributed gas in vol. – %
▶ Request nominal CO
2 max
in vol. – % from your gas supplier
If the specified values for CO
2 max
and CO
2
are listed in the following
table, the corresponding O
2
value can be read off directly from the table.
Table 23 O
2
default values depending on the nominal CO
2max
value (with the read-off example)
Read-off calculation:
Default value: CO
2
= 9.2 vol. – %
Nominal value: CO
2max
= 12.0 vol. – %
Result: O
2
= 4.9 vol. – %
