Looking along an offshore flare boom

Having selected a tip design, our engineers will then evaluate the flare tip hydraulics and generate the radiation isopleths for the various design cases at ambient conditions paying particular consideration to the solar radiation applied, relative humidity and the wind speed and direction.  This data along with a pressure flow curve for the flare tip is prepared along with a flare tip datasheet containing further information on number of pilots, pilot duty, recommended minimum purge rate, noise levels and flare tip back pressures for client review.

Pilots & Ignition System

An integral part of any flare tip supply is the associated pilot and pilot ignition and flame detection system.  Pilot burners, with few exception, are strongly recommended for all flare tip installations. The need for a reliable source of ignition is essential to safe flare tip operation, without which in a flare flame out scenario, it would be possible for large clouds of hydrocarbon gas to be released into the atmosphere.  See section 3.0 for more information on flare ignition systems.

A flare operating without a suitable ignition system and pilot burners is forced to rely on the flare flame remaining stable on the tip under all operating conditions.  With the advent of flare gas recovery technology (so called zero flaring)  the reliability of ignition systems has become even more critical.
