🔍 Key Concepts

• Difference between a rotary cup type atomizer and a pressure/straight mechanical atomizer (look for rotating parts vs a fixed swirl chamber) • How a return flow burner system routes excess fuel back from the nozzle (look for an obvious return passage or second connection) • Typical features of steam-atomizing nozzles (separate passages for steam and fuel, mixing at or near the tip)

💭 Think About

• Examine the internal passages marked A, B, and C: do they form a swirl chamber and single outlet, or do they suggest a rotating cup or multiple circuits? • Ask yourself whether you can see any path for fuel to return, or any second line for steam, or if all flow is forced through one small orifice. • Consider what part of the assembly would actually move during operation—does the sketch show any rotating cup or only fixed components with tangential ports?

✅ Before You Answer

• Verify whether there is any rotating element or cup shown in the section view. • Check if there is more than one distinct flow path (e.g., separate steam and fuel passages, or a supply and a return passage). • Confirm whether the design shows tangential slots feeding a central swirl chamber and single discharge orifice, which is characteristic of one specific type of mechanical atomizer.
