Noise abatement device and method for air-cooled condensing systems
First Claim
1. A sparger comprised of:
- a housing having a hollow center extending along its longitudinal axis containing a plurality of fluid passageways in fluid communication with a plurality of inlets at the hollow center and a plurality of exterior outlets wherein the passageways substantially reduce the fluid pressure between the plurality of inlets and outlets, and a blocking sector to direct fluid in a predetermined manner through the sparger to substantially reduce the interactive flow that would otherwise be generated by the fluid exiting the outlets.

Abstract
A noise abatement device and method to direct flow in a predetermined manner to substantially reduce the aerodynamic noise and structural vibrations produced by steam entering an air-cooled condenser in a power generating system. The interactive flow between the spargers that produces the aerodynamic noise and structural vibrations is largely eliminated by prohibiting fluid flow through selected flow regions within the spargers. The spargers include a stack of disks with fluid passageways. The fluid passageways are interrupted with continuous and undivided regions of the sparger to direct radial flow away from adjacent spargers, substantially eliminating the interactive flow.
