🔍 Key Concepts

• Boiler furnace layout and gas flow path • Function and location of superheater vs. parts placed in front of it • Purpose of screen tubes in a boiler

💭 Think About

• Think about which component is placed between the furnace and the superheater elements to reduce direct radiant heat exposure. • Ask yourself which choice is specifically intended as a "shield" or "curtain" for the superheater, not for controlling steam temperature chemically or by water injection. • Consider which parts mainly generate steam, which support structure, and which act as a protective barrier in the gas path.

✅ Before You Answer

• Identify which option is physically located in front of (upstream of) the superheater in the gas flow path. • Confirm which component’s primary job is to shield the superheater from intense furnace radiation, not just make steam. • Eliminate any option whose main function is steam temperature control rather than protection from radiant heat.
