🔍 Key Concepts

• How steam turbine blading is designed for ahead vs. astern operation • What happens to steam flow and efficiency when a turbine is run for long periods in the astern direction • Which components are primarily used/loaded in prolonged astern operation

💭 Think About

• Ask yourself: In normal service, is a marine steam turbine expected to run ahead or astern most of the time? Which set of stages is optimized for continuous operation? • Consider which choice describes a problem that would most logically result from running steam through the "wrong" or less efficient set of stages for too long. • Think about which components (glands, stages, ejectors, condensate pump) are most directly exposed to abnormal steam conditions when operating astern.

✅ Before You Answer

• Identify which turbine stages (ahead or astern) are normally designed for continuous, efficient duty and which are for short-duration maneuvering only. • Check which option involves heat buildup in the blading or casings that are not meant to carry full-load steam flow for long periods. • Eliminate options that mainly relate to condenser-side problems (ejectors, condensate pump) rather than blading exposure to prolonged astern steam flow.
