The FSX flare tip is used where stringent low noise specifications apply and savings achieved. The major advancement of the FSX series over other tip designs is that it can use low pressure wet waste steam to produce smokeless conditions. The FSX series has been designed to operate with all available pilot and ignition systems. The FSX Series tip thoroughly mixes gas, air and steam prior to combustion. Steam is used to inspirate the air through the steam injector units. The steam is evenly distributed through a number of steam injector units, angled in the side of the conical section of the tip, to achieve optimum flame characteristics. As the steam is forced through the steam injector throat, large quantities of air are inspirated and the resulting steam and air is thoroughly mixed with the gas in the protected mixing chamber prior to combustion. The Inclined angle and swirl angle settings of the steam injectors, coupled with the centre steam nozzle, have been designed to minimize burn-back and inspirated high secondary air entrainment.

The design of the mixing chamber contains and minimizes the break out noise associated with the turbulence of mixing the gas, steam and air. By utilizing the release of steam through annuli rather than orifices, the noise generated is reduced. Since steam is injected upwards through annuli into the tip throat, the noise source is directed away from the ground. The refractory lined chamber suppresses noise emission by reducing the lower frequencies generated as part of the combustion process.
The FSX flare tip individually sized for each installation.
