GENERAL FEATURES
The burners of this series represent monoblock burners made in die-cast aluminium housing with relative flange to work on heating
generators. The maximum output range is from 2100kW to 8000kW (according to the model).They can be provided in progressive or
fully-modulating version.

The fuel coming from the supply line, is pushed by the pump to the nozzle and then into the combustion chamber, where the mixture
between fuel and air takes place and consequently the flame. In the burners, the mixture bertween fuel and air, to perform clean and
efficient combustion, is activated by atomisation of oil into very small particles. This process is achieved making pressurised oil passing
through the nozzle.
The pump main function is to transfer oil from the tank to the nozzle in the desired quantity and pressure. To adjust this pressure,
pumps are provided with a pressure regulator (except for some models for which a separate regulating valve is provided). Other pumps
are provided with two pressure regulators: one for the high and one for low pressure (in double-stage systems with one nozzle).
In the double-stage burners, the electric actuator, that moves the air damper, allows the optimisation of the gas flue values, as to get an
efficient combustion. The position of the combustion head determines the burner output. The air (comburent) and fuel (light oil) are for-
ced into the combustion chamber, as to let the flame light up.
