Q

The primary purpose of the boiler internal dry pipe is to __________.

🔍 Key Concepts

• Function of a dry pipe inside a fire-tube or water-tube boiler steam drum • Difference between priming/foaming control and steam collection devices in a drum • Meaning of saturated steam vs "all moisture removed" (superheated or perfectly dry)

💭 Think About

• Ask yourself: Where is the dry pipe located in the boiler, and what is flowing around it and through it? • Which device or system in a boiler is mainly responsible for preventing priming and foaming—internal piping, water chemistry, separators, or operating practices? • Does any single internal pipe typically remove all moisture from steam, or does it mainly help improve steam quality leaving the drum?

✅ Before You Answer

• Be clear on what saturated steam is and whether it can still contain a small amount of moisture. • Distinguish between improving dryness of steam versus completely eliminating all moisture. • Consider the specific job of the dry pipe holes or slots in relation to the water level in the steam drum.
