An annular combustor comprising:a) an annular inner shell having an inner surface and an outer surface; b) a coaxial annular outer shell having an inner surface and an outer surface; c) a dome end wall connecting the inner shell and outer shell, wherein the inner shell, the outer shell and the dome end wall define an annular combustion chamber having a chamber width between the inner surface of the outer shell and the outer surface of the inner shell, wherein the chamber extends along a longitudinal axis and has an exit end opposite the dome end wall; d) a dam positioned between the dome end wall and the exit end and extending radially from at least one of the inner shell and the outer shell, wherein the dam defines a reduced flow area passageway within the combustion chamber, wherein the dam is generally perpendicular to one of the inner shell and the outer shell thereby defining a primary combustion zone between the dam and the dome, a secondary combustion zone adjacent to the dam and a dilution zone between the secondary combustion zone and the exit end of the chamber, and wherein the dam has a plurality of bores extending therethrough. 2. The annular combustor according to claim 1 wherein the dam protrudes radially outwardly from the inner shell.3. The annular combustor according to claim 1 wherein the bores extend radially through the dam.4. The annular combustor according to claim 3 wherein the dam has a circumferential face which is angled relative to the longitudinal axis such that the bores provide openings extending toward the exit end of the combustor.5. The annular combustor according to claim 1 further including a deflector located along a circumferential edge of the dam and angled to direct fluid toward the exit end of the combustor.6. The annular combustor according to claim 1 wherein the radially extending openings through the dam are spaced apart to provide an interrupted pattern at the face of the dam.7. The annular combustor according to claim 1 wherein the dam protrudes radially inwardly from the outer shell.8. The annular combustor according to claim 7 wherein the dam has a plurality of bores extending therethrough to permit fluid communication between the inner surface of the inner shell and the outer surface of the inner shell.9. The annular combustor according to claim 8 wherein the bores extend radially through the dam.10.
