1. A burner insert for a gas appliance comprising: a body of the burner insert having an inlet end and an outlet end with a central passage therebetween, and a plurality of openings disposed about the central passage;a wall disposed between the central passage and the plurality of openings, the wall having a curvature to follow the curvature of the plurality of openings;a plurality of fins coupled to the wall and arranged within the central passage;wherein each of the plurality of openings includes a rib member; wherein each rib member has a distal end from a base area, each rib member being triangular in shape and tapering from the base area to the distal end; and wherein each rib member has a curved surface extending from the outlet end into the respective opening. 2. The burner insert of claim 1 wherein: each rib member includes a first pressure drop feature adjacent outlet end; andthe plurality of openings include a second pressure drop feature adjacent the outlet end. 3. The burner insert of claim 1 wherein the central passage, the plurality of fins, and the wall cooperate to have a perimeter to opening ratio equal to or greater than 0.5. 4. A burner insert for use with a burner comprising: a cylindrical body member of the burner insert having an inlet end and an outlet end, the cylindrical body member having a central passage and a plurality of openings circumferentially disposed about the central passage;at least one fin extending radially into the central passage, the at least one fin extending axially between the inlet end and the outlet end; anda plurality of rib members, wherein one of the plurality of rib members is disposed within each of the plurality of openingswherein the at least one fin divides the central passage into at least two segments, each segment including at least two curved wall segments, each curved wall segment being disposed between the central passage and one of the plurality of openings, wherein the curvature of each curved wall segment follows the curvature of the plurality of openings. 5. The burner insert of claim 4 wherein each of the at least one fin and each of the curved wall segment includes pressure drop feature adjacent the outlet end. 6. The burner insert of claim 5 wherein each rib member includes a curved surface extending from the outlet end into the associated one of the plurality of openings, the curved surface having a first end adjacent the outlet end and a distal end disposed within the associated one of the plurality of openings. 7. The burner insert of claim 6 wherein a largest distance between the rib member and an inner wall of the associated one of the plurality of openings is equal to or less than 3.3 millimeters. 8. The burner insert of claim 7 wherein each of the at least two curved wall segment has a substantially uniform wall thickness. 9. The burner insert of claim 8 wherein the central passage, the at least one fin, and the at least two curved wall segments cooperate to have a perimeter to opening ratio at the outlet end equal to or greater than 0.50. 10. A method of operating a burner in a gas appliance comprising: providing a burner insert at one end of the burner, the burner insert having an annular body having a central passage and a plurality of openings disposed about the central passage, each of the plurality of openings having a triangularly tapering rib extending therein, each rib having a curved surface extending from an end of the body into the associated opening;providing the body with a plurality of fins extending radially into the central passage between an inlet and an outlet of the body;providing the body with a curved wall between the plurality of openings and the plurality of fins, wherein the wall has a curvature to follow the curvature of the plurality of openings; andinjecting a gas stream axially within the burner into the burner insert. 11. The method of claim 10 further comprising limiting a largest distance between the rib member and a side wall in the associated on of the plurality of openings to be equal to or less than 3.3 millimeters. 12. The method of claim 11 wherein: each rib member has a first pressure drop feature adjacent the outlet end; and,each of the plurality of fins having a second pressure drop feature adjacent the outlet end. 13. The method of claim 10 further comprising creating turbulence in the gas stream with the plurality of fins.
