SMOKELESS FLARES
Images illustrating steam assisted
flares
 |
This is our series FHP
steam assisted smokeless flare tip, with external Flarestream steam
injection nozzles arranged on an external ring.
This type of flare tip is designed
for typical refinery use, where very high efficiency, high smokeless
capacity, and very low noise is not a specific design requirement.

This is a picture of an FS
series high performance smokeless flare tip during fabrication. 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 quantity of air though
the Floanda nozzle (about 4:1 weight ratio) and the air, steam and waste
gas are mixed in the upper cone before being ignited by the pilots. This
tip is more efficient in steam usage as a result of the air entrainment
and pre-mixing, and can be designed for much higher smokeless capacities
than other types of flare tip. The Floanda injector is also extremely
quiet, and typically the noise level from the FS tip is about 12-14 dB(A)
less than a typical external type steam injection flare tip. |

good choice for the demanding service required for olefins and other
chemical plants where smokeless flaring of unsaturated hydrocarbons are
frequently required. |
