The ZEECO® HCL series flare tip provides control of smoke in a flare system through the engineered injection of steam and inspirated air. Zeeco’s unique design moves the steam injection nozzles away from the heat of the flare flame and into a position where a noise shroud can be engineered to muffle the steam injection jet noise. The HCL series flare tip uses a system of internal steam/air tubes to route a steam/air mixture from the steam injection manifold up the interior of the flare tip. It then discharges this steam/air mixture directly into the interior of the flare gas column as it exits the flare tip. The steam/ air mixture is injected at numerous points across the diameter of the flare tip – not just from the tip’s exit perimeter. This design can reduce the steam required for a particular smokeless rate by 35% or more.
Lower noise and radiation levels.
The impact of steam injection at the flare tip exit point is critical for more than just smokeless performance. The steam also “shapes” the flare flame in high wind conditions, eliminating the downwind flame impingement seen on many non-assisted flare tips. The steam also helps lower the radiation level at grade by lowering the emissivity of the flare flame and providing vertical energy to keep the flame erect in a crosswind. The HCL series reduces the overall steam injection noise level by 10-12 dBa compared to conventional steam flares. The muffler absorbs much of the noise produced from the steam nozzles while directing the noise upward, rather than down or outward to the surrounding area. The HCL series flare tip assembly comes standard with the largest steam/air injection tubes available. Each steam/air tube is equipped with investment cast inspirators on the inlets as well as highly reinforced investment cast discharge nozzles on the tube outlets.
