Rows of tubes installed along the walls, floor, and roof of the furnace are called __________.

🔍 Key Concepts

• Boiler construction and where different tubes are located in a furnace • The function of water wall tubes versus screen tubes • How downcomers and headers are arranged in a water-tube boiler

💭 Think About

• Think about which components are placed directly along the inner furnace surfaces (walls, floor, roof) to absorb radiant heat. • Ask yourself: which item in the choices is typically a vertical or membrane wall structure, rather than a pipe that just carries water from one drum/header to another? • Consider the purpose: are these tubes mainly for structural enclosure of the furnace, circulation between drums, or just for separating parts of the gas path?

✅ Before You Answer

• Verify which choice is specifically defined as forming the enclosure of the furnace (walls, floor, roof). • Check which items (downcomers, headers) mainly serve as circulation/collection parts rather than surface linings. • Make sure the term you pick is commonly used to describe a continuous tube surface forming the furnace boundaries.
