Abstract
A flame extinguishing apparatus cooperates with a flare boom conductor discharge port to vent a stream of combustible gas into the atmosphere. The apparatus includes a nozzle, positioned in and adjacent to the flare boom conductor gas discharge port, directing a shaped stream of a flame impeding fluid toward the discharge port. The fluid stream thus forms a gas penetrable quasi-barrier which extinguishes the flame and concurrently dilutes the vent gas.
Claims1
In combination with a flare boom having a main elongated conductor with a first end in communication with a source of flammable gas to be vented to atmosphere and a second end having a lip which defines a discharge port through which a stream of said flammable gas is passed into the atmosphere, a vent gas flame extinguishing means comprising:
- a pressurized source of a flame impeding fluid;
- and
- fluid distribution means in communication with said source of the flame impeding fluid;
- wherein said fluid distribution means is in said main elongated conductor positioned upstream from said lip and positioned substantially coaxially of said elongated conductor, and said fluid distribution means has at least one discharge aperture aligned to direct a stream of the flame impeding fluid toward said discharge port to define a flammable gas permeable fluid curtain transversely of said main elongated conductor.
