BURNERS FEATURES
Gas operation:
From the supply line the gas fuel passes through the gas train (filter, safety valves, gas pressure regulator and butterfly valve). The pressure
regulator sets the gas pressure within the combustion head utilization limits. Air is supplied by a fan, which may be onboard or separated depending on burner
configuration, and is channeled through an air damper.
The air damper and the gas butterfly valve are actuated by servomotors according to load curves, in order to achieve the correct proportion between fuel and air
flows, and to optimize flue gas parameters.
The adjustable combustion head can improve the burner performance by controlling the flame geometry and combustion efficiency.
Fuel and air are routed through separated channels inside the combustion head, then mixed to ignite the flame inside the combustion chamber. The ignition spark is
provided by electrodes and a high voltage transformer (a pilot flame may also be employed, depending on burner configuration).
Pre-ventilation of the combustion chamber is usually implemented according to gas directives.
The control panel, onboard or separated, allows the operator to monitor each operating phase.
