This type of flare is designed for the purpose of contain the flame in order not to make it visible from the outside and is adopted when is not required a hight combustion efficiency and its traceability is not required.
The flare consist of a burner installed at elevated position, equipped with a high-energy ignition Pilot and a flame detection system via UV scanner. The combustion air is natural conveyed from the bottom part of flame shield. Incase of specific request it’s possible to get a control system by installing an automatic damper via Termocouple immersed into the combustion chamber zone, automatically modulates the appropiate air flow, ensuring the constant combustion temperature up to a max.un max. di 800 °C (visible and adjustable from control panel).
The supporting structure is composed of a vertical flame shield, (without insulation) and specially sized to contain the flame inside.
The ignition system is automatic type, operated by the electrical panel installed of the flare’s bottom side and initially involves the pilot’s ignition and subsequently the opening of the main Biogas valve.
This Biogas Flare, unlike to elevated type, develop an influential radiation value at ground, since the flame is fully contained within the flame shield.
The gas train and all accessories such as valves, flame arrestor, pressure gauge and other, are installed inside the supporting structure.
