🔍 Key Concepts

• Moisture erosion in the low-pressure (LP) turbine last stages • How steam quality and superheat affect blade condition • What effect open valves (LP bleed steam and gland exhaust) have on steam conditions entering the LP turbine

💭 Think About

• Which choices would tend to reduce superheat or increase moisture content in the steam reaching the last stages of the LP turbine? • Does opening each of the listed valves make the steam drier or wetter at the LP turbine exhaust end? • Is there any option that clearly would NOT contribute to more moisture in the last stages?

✅ Before You Answer

• For each valve mentioned, consider whether it adds or removes energy/heat from the steam path. • Think about whether the action would increase condensation in the LP stages or help keep the steam dry. • Verify which condition directly leads to droplets impacting blades at high velocity in the last stages, causing erosion.
