🔍 Key Concepts

• Effect of turbine speed changes on condenser vacuum • Role of air removal (air ejector) versus pumps (circulating and condensate) in maintaining vacuum • How gland seal steam affects air leakage into the condenser

💭 Think About

• When you slow the turbine, what changes in steam flow and leakage paths could suddenly affect vacuum? • Which device’s main job is to remove non‑condensable gases/air from the condenser, and which devices mainly handle water flow? • How would too much or too little cooling water versus too much or too little air removal affect the condenser pressure?

✅ Before You Answer

• Identify which component is primarily responsible for removing air and maintaining vacuum, not just moving water • Check which option actually relates to preventing air from entering the condenser (through seals) versus removing air that has already entered • Eliminate any option where a change would more likely improve vacuum (lower condenser pressure) rather than cause it to decrease (lose vacuum)
