<p>An improved combustor basket (10) for a land-based combustion turbine comprises a plurality of ring segments (12,13) joined in telescoping fashion to form a constant diameter cylindrical basket; the downstream end of each ring segment (12, 13) has an extended lip (34) for improved film cooling of the interior surface of the ring segments; a combustor dome (14) is provided adjoining the upstream end of the combustor basket (10) and has an interior splash plate (28) directing a cooling air film along the interior surface of the dome wall. The combustor basket (10) includes fuel injecting means, and oval-shaped scoops (24) for directing the flow of compressed air into the combustion zone. Each ring segment (12), excluding the first, comprises an upstream cylindrical section (16), a conical section (18), and a downstream cylindrical section (20), which geometrical arrangement permits construction of a constant diameter combustor basket. The combined improvements of the present combustor basket result in more efficient and complete combustion, which results in the production of less smoke.</p> |
