  • Two stage variable annulus spray attemperator method and apparatus
    Patent number: 5041246
    Abstract: An attemperator for spraying water into a flow of steam utilizes a spray nozzle head having an inner Venturi passage. The head defines an annulus around the passage with an annular opening communicating the annulus with the interior of the passage. Side walls of the annular opening are inclined to converge at a focal point near the center of the passage. Steam passing through the Venturi passage picks up the spray which is finely atomized. A sleeve is threaded to the head for adjusting the size of the annular opening.
