Abstract:
1. A nozzle for generating a water shield suitable for protecting against heat generated during flaring of hydrocarbons in oil or gas production, the nozzle comprising a one-piece nozzle body being hollow and having a substantially circular circumference, said nozzle body comprising a first and second end and an inner and an outer surface, the first end being open and having a flange suited for coupling to a source of pressurized water, and the second end being closed, the nozzle body further comprising multiple holes extending from the inner to the outer surface, the holes being arranged in at least one row extending around at least part of the substantially circular circumference, the holes having a cross-section at the inner and outer surface of the nozzle body, wherein the holes taper from the inner to the outer surface so that the cross-section of the holes has a larger area at the inner surface of the nozzle body than at the outer surface, wherein the cross-section of each of a plurality of the multiple holes at the outer and inner surface of each such hole comprises two first opposing sides being parallel to each other and perpendicular to a centerline of the nozzle body, each such hole comprising two opposing planes extending from the outer to the inner surface of the nozzle body, each opposing plane of each such hole being limited by the first opposing sides at the outer and inner surface, and the two opposing planes of each such hole being inclined with respect to each other at an angle of 20° to 45°.
