BLOWN FLARES
Forced air
type smokeless flare tips FAB series.
The FAB series
flare is used for smokeless combusion applications, where the use of steam
is not desired. Smokeless combusion can be obtained even with heavy unsaturated
hydrocarbons gases.
There are two
modes of air supply; the first is a co-exial supply of air with the main
gas riser centrally positioned. The second is an outside seperate air riser
alongside the main gas riser. The gas is distributed in the tip to a series
of vanes with characterised slots for even gas spread into the air stream.
The air is directed
from the tip with a swirling action at high velocity and, with the even
gas spread and turbulent air mixing at the tip outlet, efficient combustion
is achieved. Secondary air is entrained by the turbulent discharge from
the tip.
The Swirling
action of the flame produces a well formed flame with low luminosity, unaffected
by wind and producing minimum downward radiation. This is achieved by supplying
up to 50% of stoichiometric air from the low pressure fan. |
