Patent ID: 7584822

Claim:
A method of positioning a plurality of spargers, comprising: producing steam in a boiler; routing the steam through a turbine bypass line; reducing the fluid pressure of the steam in the turbine bypass line by transferring a portion of the steam through the plurality of spargers, each of the plurality of spargers having a centerline axis, an outer diameter, and at least one exit aperture; positioning the exit aperture of each of the plurality of spargers in the interior of a turbine exhaust duct such that the steam transferred to the plurality of spargers is expelled into the turbine exhaust duct; positioning each of the plurality of spargers such that a ratio of the distance between the centerline axis of each of the plurality of spargers and the outer diameter of each of the plurality of spargers is greater than a predetermined ratio value to reduce aerodynamic noise and physical vibrations within the exhaust duct caused by an interaction of steam expelled from each of the plurality of spargers; and transferring the reduced-pressure steam in the bypass line to a condenser.
