A system includes a turbine (20). The turbine (20) includes a rotor, a stator, and a cooling insert (38). The rotor includes multiple turbine blades. The stator surrounds the rotor (56) and includes an inner wall surrounding the multiple turbine blades, an outer wall (70) surrounding the inner wall, and a cooling chamber (40) between the inner wall and the outer wall (70). The cooling insert (38) extends through an opening in the outer wall (70) into the cooling chamber (40). The insert (38) includes a side wall extending around an axis (80), an end wall (84) crosswise to the axis (80), a set of lateral ports extending through the side wall, and end ports (90) extending through the end wall (84). The cooling insert (38) is configured to direct a cooling fluid (78) through the set of lateral ports and end ports (90) into the cooling chamber (40). |
