Pipe & Vent Flares
The PF Pipe Flare offers an economical way to safely dispose of waste gas streams. These flares also incorporate features that enhance both performance and longevity.
Providing reliable electronic or flame front pilots completes the pipe flare package.
The standard PF flare includes wind deflectors that break up the low-pressure region on the down wind side of the flare. This reduces flame lick and leads to greatly extended life. Other features that can be provided include flame stabilizers ( for high velocity streams or low heating value gases ) and "air lock" purge reduction seals.
For low-pressure systems, we can offer a simple PF pipe vent. To increase safety, an "air lock" purge reduction seal is normally included.
When pressure is available, the sonic vents provide reduced radiation in the event of accidental ignition. And, because of the high rate of air entrapment, the dispersion characteristics are superior to a low velocity vent
High pressure Sonic Flares combine the best features of Coanda based flares with the longevity of multi-arm flares.
The flare is a result of years of studying the performance of all types of high pressure sonic flares. This flare is capable of providing low heat radiation flaring while maintaining the design principles required to ensure longevity.
The flare uses the energy associated with pressurized gas to entrain and mix large quantities of air. The difference in this multi-arm sonic flare is in the nozzle. Unlike other multi-arm flares, the flare does not lose efficiency as the size increases. The annulus design of the nozzle enhances the mixing rate of the entrained air into the primary mixing zone of flame. This highly aerated gas and air stream burns with a clean short flame and with F-Factors ranging from 0.06 to 0.10.
As an added feature, a low-pressure duct can easily be incorporated within the wind deflectors of the flare. The top of the LP duct is at the same elevation as the nozzles. This HP / LP design further reduces the possibility of continuous flame lick.
Most flares spend very little time at the peak design rate. Yet, many flares are unable to handle the conditions which happen most of the time - low flow turndown. Unlike flares which rely on large diameter uncooled surfaces, the flare ensures that combustion occurs above the flare tip. This eliminates nearly all of the continuous flame lick on the flare. And, by using properly designed wind deflectors, low flow rate flames are allowed to lift away from the flare, further reducing the chance of flame lick. These two features greatly improve longevity and guard against flare tip failure.
