FLARE SYSTEMS-Birwelco expertise
Now recognised as a world leader, the SonaJet
was originally developed by Unit Birwelco in the 1970s to meet the stringent low-radiation flaring requirements of North Sea installations.
By combining the benefits of high-pressure sonic flaring with exceptional durability in extreme conditions, the SonaJet provides guaranteed ignition under all operating conditions
The Sonajet design solution eradicates the need for annual tip change-outs and associated downtime costs – all of which makes it the most effective solution on the market. In addition, its design is extremely flexible and can be tailored to meet virtually any requirement.
A proportion of the high pressure gas is throttled and expanded to produce a low velocity gas stream, which produces a stable flame. The low pressure flame ensures a continuous ignition source for the remaining high pressure gas exiting the tip, even under maximum flow and blow-down conditions. As a result, flame lift and blow out are avoided.

API testing of the Birwelco pilot

To support our commitment to reliability and performance, the Birwelco Pilot has been rigorously tested in accordance with API 537 standards. The pilot was evaluated using both High Energy Ignition (HEI) and Flame Front Generator (FFG) systems, along with thermocouple flame detection to ensure accurate monitoring.
In all test scenarios, ignition was achieved on the first attempt within seconds, and the flame remained stable for the required duration in line with API 537. These results demonstrate the robustness and reliability of the Birwelco Pilot for both offshore and onshore applications.
