Question 1 of 27070

The internal feed pipe in a D-type marine boiler provides __________. distribution of feed water evenly throughout the water drum guidance and distribution of chemicals throughout the steam drum

🔍 Key Concepts

• Function of the internal feed pipe in a D-type marine boiler • Normal path of feedwater into the steam/water drum system • How chemical treatment is usually introduced and mixed in marine boilers

💭 Think About

• Think about where the internal feed pipe is located inside a D-type boiler and what component it discharges into. • Consider how engineers usually ensure uniform distribution of feedwater inside a large drum—what design feature helps prevent thermal shock and uneven heating? • Ask yourself whether chemical treatment is usually injected through the same internal feed pipe, or if it is more often introduced by a different arrangement or location.

✅ Before You Answer

• Verify which drum (water drum vs. steam drum) the internal feed pipe actually serves in a typical D-type marine boiler. • Confirm whether the internal feed pipe’s primary purpose is thermal and flow distribution of feedwater, not chemical handling. • Check from your engineering texts or drawings how boiler water treatment chemicals are normally introduced and circulated.
