🔍 Key Concepts

• Location of component J in relation to the furnace walls and tube banks • Difference between a water drum and a header in a water-tube boiler • How screen tubes and side water wall tubes are arranged and what they connect to

💭 Think About

• Look at where the tubes connected to J are positioned: do they form a wall of the furnace or a bank in the gas path? • Compare the size and orientation of J with the main lower drum in the illustration—does J look like a drum or a smaller header? • Ask yourself which component would logically be placed along the side of the furnace to collect or distribute water/steam to vertical wall tubes.

✅ Before You Answer

• Identify whether the tubes attached to J are part of the side wall of the furnace or a central screen bank. • Verify if J is drawn with the same scale and shape as the main water drum shown elsewhere in the figure. • Confirm that a support beam would not normally have multiple boiler tubes entering/exiting it like the component at J does.
