Abstract
A multi-swirl combustor plate is disclosed. The multi-swirl combustor plate contains a plurality of swirlers arranged around an interior section of the combustor plate, and a plurality of non-swirled holes arranged around an exterior section of the plate that had been cast as a solid section. The swirlers are preferably arranged in concentric circles, and the non-swirled holes are also preferably created in concentric circles disposed outside of the swirlers. In accordance with the present invention, each of the swirlers also preferably comprises an outer wall having a thickness greater than that of the multi-swirl plate and is an extension of the multi-swirl plate disposed in the downstream direction. Similarly, the swirler hub also has a thickness greater than that of the plate is an extension disposed in the downstream direction. Methods of making a swirler plate are also disclosed that include the step of first casting a plate comprising a center section having a number of swirlers and a solid outer section. The solid outer section is then subsequently machined to create a plurality of non-swirled holes. Preferably, two concentric rings of swirlers are cast and/or concentric ri…
