Air/Fuel Control And Power Modulation System - Riello RS 300/E BLU Installation, Use And Maintenance Instructions

AIR/FUEL
MODULATION SYSTEM
• GENERAL INFORMATION
The air/fuel and power modulation system
installed on RS burner series 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 func-
tions:
1. air and fuels are supplied in correct quanti-
ties by positioning the valves by direct servo-
control, thus avoiding the possibility of play
typical of systems used for traditional modu-
lating 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. a sequence (cascade control) of several boil-
ers by suitably connecting different units, and
activation of internal software in the individ-
ual systems (optional item).
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 functions, 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 first start-up and curve synchronization
manual is supplied with the burner.
The complete manual for checking and setting
all parameters will be provided on application.
