🔍 Key Concepts

• steam-assist atomizer construction and flow path • where primary mixing of fuel and atomizing steam must occur for good combustion • difference between swirl/whirl components and an actual mixing area

💭 Think About

• Visualize the internal path: where does fuel enter, where does steam enter, and at what point do they first fully blend together? • Which component’s main job is to combine two fluids, and which components mainly give rotation or direction to an already mixed stream? • Think about which part must provide enough volume and residence time for proper mixing before the spray exits the nozzle.

✅ Before You Answer

• Identify which option names a place where two fluids can actually combine in volume, not just change direction. • Ask: which part’s primary function is to create stable, uniform mixing, not simply to spin or guide the flow? • Confirm which term is commonly used in burner/atomizer design for the internal area where fluids are thoroughly mixed before discharge.
