Q

In which type of turbine does the steam pass through reversing chambers machined on the inner surface of the casing, causing the steam to be redirected back to the turbine wheel rim?

🔍 Key Concepts

• Steam flow paths in turbines (axial, radial, helical, reversing/return flow) • How casing shape and passages can redirect steam flow • Difference between flow direction at inlet vs outlet of the turbine wheel

💭 Think About

• Think about which turbine design uses shaped passages or chambers in the casing rather than on the blades themselves to turn the steam back toward the wheel. • Ask yourself: in which arrangement does steam leave the wheel, then get redirected and sent back toward the rim of the same wheel rather than continuing straight through? • Consider how the terms axial, radial, helical, and cross compound describe the direction(s) of flow or shaft arrangement.

✅ Before You Answer

• Check which turbine type is known for reversing or return-flow steam paths built into the casing. • Verify which option describes flow that changes direction and comes back toward the wheel rim, not just straight along the shaft. • Eliminate any option that mainly refers to shaft arrangements (multiple shafts/casings) rather than to the shape of the steam flow path inside one casing.
