ABSTRACT:
A flexible size diffuser grid assembly formed up of individual sparger units for use as a noise abatement device to reduce the fluid pressure in a predetermined manner to substantially reduce the aerodynamic noise and structural vibrations produced by a fluid moving therethrough. The sparger grid assembly is formed in a window pane grid-like arrangement of individual sparger pane units, each of which are mounted in a support frame, and each of which utilize individual stack of flat plates, the plates respectively having inlet slots and outlet slots, and interconnecting plenums, to create a series of passageways to substantially subdivide the flow stream of steam into smaller portions to reduce fluid pressure. The individual sparger units can be formed of a standard size, or instead formed of custom sizes, and greater or less numbers of individual window pane sparger units can be used in the frame, depending on the given end-use application.
