🔍 Key Concepts

• Function of a steam separator in a whistle line • Why whistle steam must be kept dry and clean • Purpose of different drain systems: main turbine, low-pressure, contaminated, high-pressure

💭 Think About

• Ask yourself what kind of impurities or conditions might be in the steam whistle line and where those should safely be discharged. • Consider which drain system is designed to handle oily, dirty, or potentially contaminated condensate versus clean condensate. • Think about whether you would ever want whistle-line drainage to flow back toward machinery like the main turbine, and why or why not.

✅ Before You Answer

• Identify which drain system is intended for potentially dirty/contaminated condensate. • Verify which system would never be appropriate for returning whistle-line drainage (e.g., directly to the main turbine). • Match the whistle’s purpose (safety/ signaling, not power) with the most suitable and safest drain system.
