Combustor of a gas turbine

摘要

The combustor (1) has at least a portion (4) comprising an inner liner (5) and an outer cover plate (6) defining with the inner liner (5) an interposed cooling chamber (7). From the liner (5) a plurality of hollow elements (9, 9f) protruding into the cooling chamber (7) extend. Each hollow element (9, 9f) defines a damping volume (10) connected to the inner of the combustor (1) via a calibrated duct (11). During operation the hollow elements (9) damp pressure pulsations and, in addition, also transfer heat.
