🔍 Key Concepts

• Flow direction shown by INLET and OUTLET arrows in the illustration • How a boiler steam drum feed inlet is designed to prevent thermal shock (sleeves, diffusers, mixing with drum water) • Typical shapes/connections of a safety valve nozzle versus normal steam or feed nozzles on a drum

💭 Think About

• Look at where the INLET arrow is located and think about what medium would be entering the steam drum there – is it superheated steam, saturated steam, or relatively cold water? • Notice the long inner sleeve/tube and the annular space around it. What boiler-drum connection usually needs this kind of internal sleeve to protect the drum metal? • Ask yourself which of the choices would normally require a simple short stub nozzle, and which would require a more elaborate internal arrangement like the one shown.

✅ Before You Answer

• Verify which connection to the steam drum must handle large temperature differences between incoming fluid and drum contents • Confirm which of the listed nozzles would most likely include a thermal sleeve or diffuser extending well inside the drum • Eliminate any choice that typically connects to the drum by a short, direct nozzle without an internal sleeve (consider how safety valves and steam outlets are usually mounted)
