AIR-ASSISTED SMOKELESS FLARES
A guy-supported air-assisted
smokeless flare. Flaregas air assisted flares are co-axial, with the gas
passing to the flare tip in the inner gas riser.
The air for smokeless combustion is provided by low pressure air assist fans
located at the base of the stack, and conducted to the flare tip in the annular
space between the gas riser and the outer air duct. The outer air duct becomes
the structural support for the stack, which can be self-supported, guy-supported
or supported using a derrick structure - normally depending on the height of the
flare.

Another image of a Flaregas air-assisted
smokeless flare. Our air assisted flares can be designed for very
high smokeless capacity, and can also be designed with partial steam
assist to enhance smokeless combustion of very heavy gases |
Self-supported flares can
frequently be erected in one piece with very limited modification to the
structural design. In these images, a 175ft tall self-supported air-assisted
smokeless flare system is being lifted in one piece after being put together
horizontally on the ground. All of the piping laders, and platforms are
installed on the stack prior to lifting.

This is an image of a clustered
flare, with multiple gas risers and flare tips.
The stack is self-supporting, with
both steam and non-assisted flare tips. |
==========================================================================
Flaregas designs de-mountable derrick structures which permit
multiple flares to be supported from a single structure. The system allows each
flare to be mounted and de-mounted for maintenance without shutting the other
flares on the structure down
In these images, a 60" diameter steam assisted flare tip, labyrinth gas
seal and riser are being mounted on a structure 145m overall height, with the
60" diameter flare shown on the right side in service.
