Steam assisted smokeless fares This is our series FHP steam assisted smokeless flare tip with external Flarestream steam injection nozzles arrange on an external ring. This type of flare tip is designed for typical refinery u where very high efficiency, high smokeless capacity, and very low noise is not a specific design reuirement. This is a picture of an F! series high performance smokeless flare tip during fa"rication. This style of flare tip uses a totally different type of steam injection. Floanda #internal coanda$ nozzles are located in a cone at the top section of the tip. The steam entrains a large uantity of air though the Floanda nozzle #a"out %&' weight ratio$ and the air, steam and waste gas are mixed in the upper cone "efore "eing ignited "y the pilots. This tip is more efficient in steam usage as a result of the air entrainment and pre(mixing, and can "e designed for much higher smokeless capacities than other types of flare tip. The Floanda injector is also extremely uiet, and typically the noise level from the F! tip is a"out ')('% d* #+$ less than a typical external type steam injection flare tip. +n F!(% flare tip in operation at a -! ulf /oast olefins complex. F! series flare tips are a good ch demanding service reuired for olefins and other chemical plants where smokeless flaring o hydrocar"ons is freuently reuired
