1 .1 .4 Modulating-controlled burner

Control:
Main burner continuous
The butterfly valve for air is moved
to the position for minimum capac-
ity in order to start the main burner.
The main burner is started with
minimum capacity after the operat-
ing signal from the pilot burner has
been detected. The control system
controls the burner capacity via the
butterfly valve for air after the oper-
ating state has been signalled. Pilot
and main burners can be operated
simultaneously. This reduces the
time required by the main burner for
starting up.
