🔍 Key Concepts

• single-element vs multi-element feedwater control in boiler operations • how load changes affect steam flow, drum level, and feedwater flow • the purpose of adding a second measured variable in a two-element controller

💭 Think About

• Ask yourself: in a one-element regulator, what single variable is measured and controlled, and what problem does this have during rapid load changes? • For a two-element regulator, which extra measurement helps the controller respond faster to changes in steam demand before the drum level actually shifts? • Which pair of variables together best represents both the cause (load change) and the effect (water inventory change) in the boiler drum?

✅ Before You Answer

• Identify what a one-element (single-element) system measures; the two-element system must add something to this, not replace it. • Decide which variable changes immediately with load (steam demand) and which variable represents the stored water in the drum. • Eliminate any option where the two variables do not clearly represent both the load change and the drum water level behavior.
