Abstract
A flare tip assembly includes a barrel having a barrel wall with an inner surface and an outer surface, an interior cavity defined within the inner surface and extending axially through the barrel, and internal channels formed through the barrel wall. The internal channels have a first opening at a lower axial end of the barrel wall and a second opening at an opposite, upper axial end of the barrel wall, and the internal channels are enclosed between the inner surface and the outer surface of the barrel wall. The flare tip assembly further includes a pilot positioned proximate to the upper axial end of the barrel.
Claims6
A method of cooling a flare tip, comprising:
- providing a flare tip on a flare stack,
- wherein the flare tip comprises a wall and an internal channel extending along the wall from a lower axial end proximate the flare stack to an upper axial end;
- providing a supply line along the flare stack,
- wherein the supply line comprises an outlet positioned proximate the lower axial end of the flare tip;
- supplying a cooling fluid through the supply line;
- spraying the cooling fluid from the outlet into the internal channel at the lower axial end of the flare tip;
- and
- using heat from a flame from the flare tip to evaporate the cooling fluid as the cooling fluid moves through the internal channel,
- wherein evaporation of the cooling fluid cools the wall of the flare tip and comprises:
- increasing a heat dissipation rate;
- increasing a heat conduction rate in the flare tip through an application of a high thermal conductivity material on an outer surface of the flare tip, the high thermal conductivity material comprises a copper material;
- minimizing heat absorption by applying a low emissivity material on an inner surface of the flare tip;
- and
- increasing a thermal convection rate.
