Turbine casing with false flange

1. A turbine casing, comprising:

an outer surface;

the outer surface comprising a solid false flange; and

an inner surface;

the inner surface comprising a heat sink positioned adjacent to the solid false flange for heat exchange between the heat sink and the solid false flange.

2. The turbine casing of claim 1 , wherein the heat sink comprises one or more fins.

3. The turbine casing of claim 2 , wherein the one or more fins are separated.

4. The turbine casing of claim 2 , wherein the one or more fins comprise a uniform shape.

5. The turbine casing of claim 2 , wherein the one or more fins comprise a plurality of shapes.

6. The turbine casing of claim 1 , wherein the heat sink projects within the casing.

7. The turbine casing of claim 1 , wherein the turbine casing comprises a plurality of sections meeting at a plurality of joints and wherein one or more of the plurality of joints comprises a joint heat sink.

8. A turbine casing, comprising;

a plurality of sections;

the plurality of sections comprising a plurality of flange joints;

each of the plurality of sections comprising an outer surface;

a solid false flange positioned on the outer surface of one or more of the plurality of sections; and

each of the plurality of sections comprising an inner surface;

a false flange heat sink positioned about the solid false flange on the inner surface of one or more of the plurality of sections.

9. The turbine casing of claim 8 , wherein one or more of the plurality of sections comprises a joint heat sink positioned about one or more of the plurality of flange joints.

10. The turbine casing of claim 8 , wherein the false flange heat sink and/or the joint heat sink comprise one or more fins.

11. The turbine casing of claim 10 , wherein the one or more fins are separated.

12. The turbine casing of claim 10 , wherein the one or more fins comprise a uniform shape.

13. The turbine casing of claim 10 , wherein the one or more fins comprise a plurality of shapes.

14. The turbine casing of claim 10 , wherein the one or more fins project within the casing.

15. A method of stabilizing a turbine casing having a number of sections with one or more false flanges positioned thereon, comprising:

determining the average radial deflection of each section;

subtracting the minimum radial deflection of each section; and

adding a heat sink to one or more of the false flanges to reduce the average radial deflection of each section.

16. The method of claim 15 , further comprising absorbing heat by the heat sink during turbine start up.

17. The method of claim 15 , further comprising maintaining heat by the heat sink during turbine shut down.

18. The method of claim 15 , wherein the number of sections meet at flange joints and wherein the method further comprises adding a flange joint heat sink to one or more of the flange joints.
