Question 1 of 27070

Q

Which of the following methods is used to counter axial thrust in a single flow reaction turbine?

🔍 Key Concepts

• How axial thrust is created in a single-flow reaction turbine and why it must be balanced • Which components are specifically designed to oppose or balance thrust along the shaft, rather than seal leakage • The difference between thrust-balancing devices and sealing/packing arrangements

💭 Think About

• First, think: which option directly provides a force in the opposite direction of the axial thrust on the rotor, rather than just reducing leakage? • Ask yourself: which of these devices is usually placed so that pressure can act on an area to balance thrust, instead of simply acting as a seal? • Consider: in a single-flow turbine, steam flows one way, producing thrust in one direction. Which method uses steam pressure in a controlled space to push back on the rotor and counter that thrust?

✅ Before You Answer

• Identify which listed device is specifically known as a thrust-balancing arrangement in turbines • Separate in your mind which items are mainly sealing devices (to control leakage) versus those that develop counterthrust • Verify in turbine diagrams which component is located where axial thrust is highest (inlet end) and is shaped to present an effective area for pressure to act on
