Abstract
A cylindrical combustion chamber housing of a gas turbine, in which the compressor air is fed into the lower, conical part of the combustion chamber housing, the perforated cone (5), through a lateral, arc-shaped inlet elbow (2). The inlet elbow (2) is directly joined by the intake distribution element (1), in which the compressor air is led around the perforated cone (5) on both sides. The tangential flow is converted around a cone into an axial flow through the holes (7) in the perforated cone (5). The conversion of the direction of flow of the compressor air is supported by radially arranged ribs (3). As a result, optimal cooling of the entire injector tube (6) is achieved, while the pressure drop in the air feed area (1, 2 and 5) is minimized, and the efficiency of the gas turbine is increased at the same time.
