Air/fuel adjustment and output modulation system
General remarks
The air/fuel and power modulation system installed on burner provides, a set of integrated functions ensuring top level energy and
operational performance from the burner, both for single and grouped burners (e.g. boiler with a double combustion chamber or
several generators in parallel).
The system includes the following basic functions:
1. air and fuels are supplied in correct quantities by positioning the valves by direct servo-control, thus avoiding the possibility of
play typical of systems used for traditional modulating burners, in which settings are obtained by levers and a mechanical cam;
2. burner power is modulated according to the load required by the system, while boiler pressure or temperature is maintained at
set operating values;
3. Fine, continuous correction of the airflow according to the analysis of the flue gases at the stack (O
with the O
kit containing the PLL module and the QGO2 sensor;

4. Measurement of the combustion efficiency; this function is associated with the O
5. a sequence (cascade control) of several boilers by suitably connecting different units.
Further interfaces and computer communication functions for remote control or integration in centrally supervised systems are
available according to the system's configuration.
NOTE
The first start-up and all further operations concerning internal settings of the control system or expansion of basic fun-
ctions, are accessed with a password and are reserved for technical service personnel specifically trained for internal
programming of the instrument and for the specific application obtained with this burner.
The instrument's reference handbook is supplied during the technical service training.
