BURNERS FEATURES
These burners are designed to be installed into boilers provided with very big combustion chamber but the tube nest very close to the
burner stokhole. The flame produced by this burner series is very short, but has the energy necessary to take up all the combustion
chamber and then exchange this energy to the water, as to get very high efficiency. The construction and test of these burners are per-
formed both in laboratories and directly on site, observing the peculiarities of these boilers: the need to operate in slight depression and
to heat the boiler in low flame for a long time before exploiting the highest performance. The flame is divided into smaller flames perfor-
ming the same output but distributing the energy uniformly without stressing the boiler structure. To complete this product range, the
flame modulation is performed by a modulator with pressure probe connected to. These burners can be provided for all kinds of fuels
and can be designed according to the customer requests. They are provided with all the safety requirements according to the Stan-
dards in force These burners can be installed in the newest microprocessor-controlled systems.
Gas operation: the gas coming from the supply line passes through filter, gas valves and pressure regulator. This one forces the pres-
sure in the utilisation limits. The electric actuator , that moves proportionally the air damper and the gas butterfly valve, uses an adju-
sting cam with variable shape. This one allows the optimisation of the gas flue values, as to get an efficient combustion. The
combustion head positioning determines the burner’s output. The combustion head determines the energetic quality and the geometry
of the flame. Fuel and comburent are routed into separated ways as far as the zone of flame generation (combustion chamber).
The control panel , placed on the burner’s front side, shows each operating stage.
Gas categories and countries of application
(*) Premix type ...N burners are not enabled to work with these gas categories.
The above gas groups can be combined according to the standard EN437:2021 and national situation of countries.
CAUTION: pay attention to the burner mounting; all the blast tubes must get into the combustion chamber, going further than the inner
side of the boiler fetling.
