Which of the listed boiler components is used to equalize the distribution of water to the generating tubes and provide an area for the accumulation of loose scale and other solid matter present in the boiler water?
• Function of water drum and headers in a water-tube boiler • Difference between downcomers and generating tubes • Where sludge, scale, and solids tend to collect in a boiler
• Think about which boiler parts are primarily for circulation versus which are used for collection and distribution of water to the generating tubes. • Ask yourself: where would it be easiest to remove sludge and scale during blowdowns or inspections? • Consider which component(s) are located at the lower part of the boiler where heavier solids naturally settle.
• Identify which component is specifically designed to collect loose scale and solids rather than just move water. • Confirm which parts actually distribute water to the generating tubes (not steam). • Verify which option(s) are found at the bottom of the boiler, where gravity will cause solids to accumulate.
