🔍 Key Concepts

• Steam drum internal components: distinguish between steam outlets, downcomers, internal feed pipe, and baffles. • Feedwater distribution: where incoming feedwater is usually discharged to avoid thermal shock and to promote good circulation and separation. • Look at the external feed line entering the drum shell and trace where it connects inside the drum.

💭 Think About

• On the illustration, find the pipe that brings water from outside the drum into the shell, then follow that pipe to see which labeled internal part it feeds. • Compare the positions of labels B, E, J, and L: which one is clearly part of a horizontal distribution pipe with holes or fittings meant to spread incoming water? • Ask yourself which labeled items are clearly NOT in the water space (for example, fittings on the top of the drum or baffles) and eliminate those from consideration.

✅ Before You Answer

• Verify which label is attached directly to the internal feed pipe or nozzle that runs near the bottom of the steam drum water space. • Confirm that the chosen label is connected, directly or via a short section, to the external feedwater line entering the drum from outside. • Make sure the item you pick is not a baffle, dry pipe, or steam outlet, but specifically the component that introduces cooler feedwater into the drum water space.
