Abstract

La invención hace referencia a un componente de turbina de gas (8) refrigerado para una turbina de gas, con una superficie (38) que puede exponerse a un gas caliente (39), en la que desembocan varias aberturas de refrigeración por película (36), en donde cada una de las aberturas de refrigeración por película (36) implicadas presenta a lo largo de su dirección de circulación un segmento de canal (48) y un segmento del difusor (46) que se conecta directamente al segmento de canal (48), que comprende un borde del difusor (40) dispuesto aguas arriba, dos bordes longitudinales de difusor (42) y un borde del difusor (44) dispuesto aguas abajo, en donde cada borde longitudinal (42) coincide en una zona de esquina (54) con el borde del difusor (44) dispuesto aguas abajo. Para obtener una disposición eficaz de las aberturas de refrigeración por película (36), cuya película refrigerante esté configurada cerrada más cerca que hasta ahora detrás del borde del difusor dispuesto aguas abajo, se propone que estén conformadas al menos dos aberturas de refrigeración por película (36) de la fila (30, 34) directamente adyacentes, de forma preferida todas, de tal manera que sus ejes de canal (50) de los respectivos segmentos de canal (48) estén inclinados con relación a la dirección local de circulación (52) del gas caliente (39) y sus segmentos del difusor (46) estén configurados respectivamente asimétricamente, de tal manera que las zonas de esquina (54) directamente adyacentes de las aberturas de refrigeración por película (36) implicadas, según se observa en la dirección de circulación (52) del gas caliente (39), se alineen.
