A system 10 includes a turbine 32 configured to expand a gas flow. The turbine includes a turbine rotor, such that the heated gas flow rotates the turbine rotor about an axis and a turbine casing 58 is disposed around the turbine rotor. A cooling manifold 76 directs a low pressure cooling fluid toward the turbine casing such that the low pressure cooling fluid cools the turbine casing 58 and controls the clearance between the turbine rotor and the turbine casing. Corresponding method for controling the clearance between the turbine rotor and the turbine casing. |
