Abstract

Un combustor para una turbina de gas que tiene una zona de combustión primaria y una zona de combustión secundaria. El combustor tiene canutos depulverización del combustible gaseoso primario para suministrar una mezcla pobre decombustibl e gaseoso a la zona de combustión primaria por medio de unprimer conducto del pasaje anular de pre-mezclado y barras de pulverización del combustible secundarias para suministrar una mezcla pobre de combustiblea la zona de combustiónsecundaria p or medio de un segundo conducto de pasaje anular de premezclado. Las barras de pulverización del combustible estánconformadas aerodinámicamente y una hilera de bocas de descargas del combustible están formadas en ladosopuestos de las ba rras de pulverización. Unpar de aletas mezcladoras proyectan hacia afuera de los lados de las barras de pulverización. Las aletas crean turbulencia en el flujo de aire que aseguraadecuado mezclado del combustible y aire. Lasaletas tienen suficiente altura y están desplazadas suficientemente lejos desde las bocas de descarga delcombustible de modo que aunque la turbulencia no se haya disipado cuando el flujo de aire alcanza las bocas de descarga del combustible,las zonas derecirculación ubicadas corriente abajo de las aletas no se prolonga a las bocas de descarga de combustible. Esto asegura que las barras de pulverización noactuarán como contenedores de llama ni hará que la combustión se produzcaprematuramente dentro del con ducto de pasaje de premezclado.
