2nd flame valve allows the diesel oil, at a pressure of 12 bar, to
reach the 2nd nozzle and the burner to operate at full capacity. From
the time the flame appears in the combustion chamber, the burner is
controlled by the photoelectric cell and thermostats.
The command equipment continues the program and disconnects
the ignition transformer. When the temperature or pressure in
the boiler reaches the value to which the thermostat or pressure
switch is calibrated, its intervention will cause the burner to stop.
Subsequently, if the temperature of pressure decreases below the
lower thermostat or pressure switch threshold value, the burner will
switch on again. If, for any reason, the flame is lost during burner
operation, after just one second the flame control device cuts off the
power supply from the corresponding relay to automatically switch
off the electrovalves which intercepts the nozzle flow. The switch on
stage is thus repeated and, if the flame ignites again normally, the
burner starts working again normally, if not (if the flame is irregular
or fails to light completely) the equipment goes automatically into
lock-out (LED 7). If the program is interrupted (due to a power supply
failure, manual action or the intervention of the thermostat, etc.)
during the pre-wash stage, the programmer returns to its starting
position and will automatically repeat the whole of the burner ignition
sequence.
The selection of the nozzles in function of the desired total
flow rate (2 nozzles in operation) must be made accounting
for the flow rate values that correspond to the diesel operating
pressure of 12 bar. It is of course possible to vary within wide
limits the relationship between the first and the second flames
by replacing the nozzles.
