APPLICATION
The PM-7 burners can be used on
all types of industrial heating
equipment such as hot water boilers
steam boilers, air heaters, and
almost all types of heat processing
equipment.
FUEL
SPECIFICATION
Oil: All grades from Light Distillate
to Heavy Residual fuels.
Gas: Natural Gas.
REGULATION
The PM-7 burners are fully modulating
and the servo driven motor along
with the built in cams controls
the regulation of the air and
fuel to maintain an optimum combustion
with a reduced excess air figure
at constant air fuel ratios.
Turn down ratio: Oil 1:4
Gas 1:6
IGNITION
Oil operation: Direct ignition
of the oil by high voltage spark.
Gas operation: high voltage spark
ignition of a separate gas pilot
burner.
FLAME
MONITORING
Oil & Gas operation on: U.V.
Cell
COMBUSTION
AIR SUPPLY
Air necessary for the optimum
combustion of the fuel with an
adequate pressure to overcome
the boiler resistance are selected
so that the system can perform
with the highest efficiency on
the most difficult combustion
chambers. The result is reduction
in the excess air and high combustion
efficiency.
MINIMUM
GAS PRESSURE REQUIRED AT BURNER
HEAD: 800mm WG.
OIL SUPPLY: PRESSURE 30 kg/cm2
(425psi), VOLUME Min.1.5 TIMES
THE MAXIMUM NOZZLE OUTPUT.
