1 .1 .3 Two-stage-controlled main burner
with permanent pilot burner
Control:
Main burner ON/OFF with ignition
via bypass
The main burner can be started
with minimum capacity after the
operating signal from the pilot
burner has been detected. When
the operating state is reached, the
BCU issues the Enable signal for
the maximum burner capacity. Pilot
and main burners can be operated
simultaneously. This reduces the
time required by the main burner for
starting up.
The BCU provides the cooling and
purging processes.
