Flare Tip FC Series is used where environmental considerations allow low rate smoke production with heavier gases or where the gases are not inherently smoke producing.
The FC series Flare Tip has a low noise multi port centre steam nozzle fitted into the flare tip. Steam is injected into the gas stream and allowed to mix fully before the gas reaches the flame envelope. The specific heat capacity of the steam absorbs some of the available heat and results in a lower flame temperature thus retarding thermal cracking and reducing smoke production from unburnt carbon particles.
Injection of steam into the flare tip, results in increased exit velocity which inspirates large volumes of air into the flame envelope and aids smokeless combustion.
The FC series is supplied as standard with a perforated windshield to prevent flamelick and to help cool the top of the flare tip closest to the flame envelope. However, with a constant wind direction or where the land formation around the site creates unusual eddy air currents, a heat shield is supplied to give greater protection.
The unique refractory lining system is secured to the tip by heat resistant steel bull horn sprags. Many thousands of fine stainless needles are mixed thoroughly with the refractory to reinforce the material evenly over the full depth of refractory without producing expansion/contraction shear planes. This refractory installation procedure has been developed and proven over many years to give the longest possible operating life even in the most arduous conditions.
In order to prevent flame lift off from the tip, the FC series has bluff bodies positioned above the refractory lined upper section of the flare tip.
The FC series has been designed to operate with all available pilot and ignition systems, e.g. Natural Draught, Natural Draught Splitter System and Forced Draught. These are fully described in our Technical Bulletins.
