Production Mode
In concentration or gas flow controlled systems, it must always be decided which parameter
should be the constant setpoint and which the variable parameter. The setpoint highlighted in
gray is always the calculated value (variable).
Constant
Concentration /
Variable Gas Flow
The ozone concentration is the constant setpoint:
Depending on the required ozone mass, the gas flow is
changed variably.
Constant Gas Flow /
Variable
Concentration
The gas flow is the constant setpoint:
depending on the required ozone mass, the ozone
concentration is changed variably.
Example calculations:
Variable Gas Flos
= Required Ozone Mass /
Constant Concentration
49.02 Nm³/h
= 5000 g/h /
102.0 g/Nm³
39.22 Nm³/h
= 4000 g/h /
102.0 g/Nm³
Variable Concentration
= Required Ozone Mass /
Constant Gas Flow
148.0 g/Nm³h
= 5000 g/h /
33.8 Nm³/h
118.3 g/Nm³
= 4000 g/h /
33.8 Nm³/h
Required Ozone Mass
The Required Ozone Mass is displayed as follows:
SP
Setpoint in g/h, according to the design data oft he system.
PV
Actual value in g/h, showing the actual Process Value in g/h.
Calculation
In the calculation, the required ozone mass is divided by the constant setpoint (green). The
result is the variable parameter (gray) that must be set to produce the required ozone mass.
Formula
See calculation basis.
SP
Setpoint in g/Nm³, Nm³/h.
Gray highlighted value = calculated value or correction value
Green highlighted value = default setpoint
PV
Actual value in g/Nm³, Nm³/h, showing the actual Process Value.
